Continuous in vivo monitoring of diverse chemicals, including ions, glucose, and neurotransmitters, is pivotal for elucidating complex physiological processes and identifying various diseases. Existing approaches predominantly rely on transdermal wires to transmit signals from implanted sensors to external devices, which substantially heightens the risk of infection, particularly in immunocompromised patients. To address this problem, we developed an interface-free implants-to-textile wireless system for multiplexed in vivo chemical monitoring. This system integrates fully implanted miniature wireless sensors, roughly the size of a grain of rice, with a conformal textile-based network of intermediate relay coils. These implanted sensors convert chemical signals into distinct resonance frequencies and wirelessly relay them through the textile–coil network to a readout coil. By obviating the need for transdermal wires, our system mitigates infection risk and achieves real-time and simultaneous monitoring of glucose, potassium and calcium ions in vivo. This minimally invasive platform offers safe, real-time, multiplexed chemical analysis, thereby contributing to advancing both disease diagnosis and understanding of intricate physiological dynamics.

In recent years, due to the development of flexible electronics, flexible sensors have been widely concerned and applied in intelligent robots, brain-computer interfaces, and wearable electronic devices. In this paper, we propose a low-cost and high-efficiency sensor component preparation method. The sensor component tetrathiafulvalene-tetracyanoquinodimethane/melamine sponge (TTMS) takes a melamine sponge as a flexible substrate. And the sponge is metallized with the tetrathiafulvalene-tetracyanoquinodimethane (TTF-TCNQ) which is an organic conducting molecule to construct a conductive pathway. The physical load approach is used to ensure the advantages of low cost and efficient manufacturing. TTMS can withstand 8000 compression cycles which exhibits its good mechanical stability. And 1000 cycles of cyclic voltammetry scanning proved it also had good electrical stability. TTMS can distinguish pressure changes of 100 Pa and respond quickly to pressure application and release. The TTMS can be assembled to form an array of sensors that can distinguish the position and intensity of pressure. Therefore, the excellent performance of the sensor is expected to promote the commercial application of the piezoresistive sensor.

Numerous efforts can improve reversible capacity and long cycling stability for lithium-sulfur (Li–S) batteries, however, challenges remain in achieving high sulfur utilization and suppressing the shuttle effect , especially for cells with a low electrolyte/sulfur (E/S) ratio. In this research, we utilize tetrathiafulvalene (TTF) as multifunctional catalyst for high-performance Li–S batteries through optimizing electrolyte chemistry for the first time. With TTF additive in electrolyte, it acts as π-electron donor molecule to improve the electron transport of Li 2 S x due to the van der Waals interaction , and promote LiNO 3 to Li 3 N to form highly conductive passivation layer on lithium anode (Li-anode). Furthermore, TTF functions as a catalyst to improve the redox kinetics of Li 2 S x thus slowing down the “shuttle effect”, improve the utilization of sulfur, and protect the Li-anode. As a result, the cell with TTF exhibits excellent performances with high discharge capacity (1359 mAh g −1 at 0.1C), long-term cycling stability (509 mAh g −1 after 500 cycles at 0.5C), and excellent cycling performance even at low E/S ratio (5.5 μL mg −1 ) (initial discharge capacity of 1129 mAh g −1 with a capacity decay rate of 0.20% per cycle at 0.1C for 200 cycles).

Advancement of wearable microelectronics demands their power source with continuous energy supply, skin-integration and miniaturization. In light of poly (vinyl alcohol) (PVA) hydrogel with nontoxicity, good biocompatibility and low cost, an advanced wearable PVA-based hybrid biofuel cells (HBFCs) with high self-adhesiveness was developed. Through the reaction between PVA molecules and succinic anhydride (SAA), the carboxylated PVA (PVA/SAA) was obtained, and by incorporation with PDA as crosslinker , the self-adhesive PVA/SAA-DA hydrogel electrolytes formed by dual covalent and hydrogen bonding . With increasing SAA and PDA content, the pore size decreased, and a uniform and dense network formed, endowing the hydrogel with a relatively high absorption capacity of PBS solution of lactate as cell fuel. Meanwhile the various functional groups of hydrogel, including catechol , quinone , amino and hydroxyl groups , contributed to impressive tissue adhesion strength against pigskin under dry and wet conditions. The PVA/SAA-DA hydrogel displayed high conductive property, and the integrated PVA-based HBFC generated open circuit voltage of 0.50 V and maximum power density of 128.76 μW/cm 2 in 20 mM lactate solution, which was optimized to be 0.57 V/224.85 μW/cm 2 when the pore size was enlarged. The power retention reached above 70% in one week, showing long-term stability of HBFC. The PVA-based HBFC was further adhered to human skin without extra adhesive tapes to scavenge human sweat as biofuel, and the maximum power density reached 85.34 μW/cm 2 , while by connected with a DC-DC converter, the HBFC could power watch, exhibiting promising application potentials as wearable electronic device to provide bioelectricity .

BACKGROUND The large-scale practical application of CO 2 capture using carbonate solutions is mainly limited by their low CO 2 absorption rate. In view of this, it is feasible to improve CO 2 capture performance of carbonate solution by adding additives. In this paper, low-cost sodium carbonate (Na 2 CO 3 ) solution was selected as the main CO 2 absorbent, and the effects of different organic additives on CO 2 capture performance of Na 2 CO 3 solutions were systematically investigated. RESULTS The results showed that 0.04 mol/L tetrabutylammonium bromide (TBAB) could achieve a better enhancement effect on CO 2 capture performance of Na 2 CO 3 solution. After addition of TBAB, the maximum CO 2 absorption rate of Na 2 CO 3 solution was improved to 2.52 × 10 −3 mol/min, which increased by 105%. And the maximum CO 2 desorption rate could also be improved by 45%. TBAB/Na 2 CO 3 system not only realized a high CO 2 absorption capacity of 0.769 mol/mol, but also maintained 82% of the initial CO 2 absorption capacity after three cyclic tests. The regeneration heat duty of TBAB/Na 2 CO 3 solution was calculated to be 1136.6 kJ/mol, which was significantly lower than that of single Na 2 CO 3 solution and conventional MEA aqueous solution. The promotion mechanism of TBAB in Na 2 CO 3 solution was explored using Fourier transform infrared spectra (FTIR) and 13 C nuclear magnetic resonance (NMR) analysis. CONCLUSION The introduction of TBAB additive could significantly improve CO 2 capture performance of Na 2 CO 3 solution and reduce regeneration heat duty, making it a possible option in the field of post-combustion CO 2 capture. © 2023 Society of Chemical Industry (SCI).

High-performance plasmonic substrates have recently attracted much research attention. Herein, a three-dimensional gold nanoparticles (AuNPs) spherical liquid array (SLA) with high “hot spots” and tunable nanometer gap by optimizing the proportion of AuNPs colloids over chloroform was synthesized based on a water–oil interfacial self-assembly strategy. The substrate demonstrated excellent surface-enhanced Raman scattering (SERS) performance using tetrathiafulvalene and rhodamine 6G (R6G) as probe molecules. With a simple extraction and soaking pretreatment process, the SLA exhibited high sensitivity for analysing triazophos on apple peels, with a limit of detection (LOD) of 0.005 µg/mL and recovery ranging from 96 to 110 %. Particularly, the chloroform produced an inherent characteristic peak at 665 cm −1 , which was used as the internal standard to correct SERS signal fluctuation, leading to an improvement of the corresponding coefficient R 2 from 0.97 to 0.99, thus improving the reproducibility. Therefore the SLA substrate possesses the potential for quantitative analysis of food contaminants.

Elemetal doping is an efficient strategy to adjust the microstructue and electronic property of a carbon material, as a result, shows great potential in the design of novel electromagnetic absorption (EMA) materials. In this work, we report an useful strategy to prepare a N,S co-doped carbon (NSC) using TTF-TCNQ as the precusor, and systematically explore its frequency-depedent dielectric and EMA properties. Different N/S ratios can be tuned by the regulation of pyrolitic temperature. The derived NSC exhibits wonderful EMA performance when the pyrolytic temperature is setted to 700 ℃ with loading ratio of 35 wt%. Efficient absorption can be achieved in the frequency range of 6.4–18 GHz. Moreover, it is determined that the efficient absorption bandwidth gets to 6.5 GHz, while the maximal absorption reaches −46 dB. The EMA mechanism of NSC is considered to be mainly contributed by improved impedance matching realized by macropores, enhanced conductance loss caused by well constructed condutive network, and polarization by N,S doping. This research provides a new idea for development of novel carbon materials for EMA applicaion.

In this work we report the catalytic effect of 5,10,15,20-tetraphenylporphyrin (H 2 TPP) on the reduction of oxygen (O 2 ) by a weak electron donor, namely tetrathiafulvalene (TTF), at the polarized water/1,2-dichloroethane (DCE) interface. TTF alone, as reported previously, can reduce O 2 slowly via a four-electron transfer pathway to produce water. Herein we show that H 2 TPP can catalyze the reduction of O 2 by TTF to form hydrogen peroxide (H 2 O 2 ) at the water/DCE interface, which was investigated by voltammetry and biphasic shake-flask experiments. The overall process was found to be essentially a proton-coupled electron transfer reaction. And the results also proved that the catalytic activity of H 2 TPP toward O 2 reduction under acid condition arises from the polarization activation of O 2 by H 2 TPP diacid, namely H 4 TPP 2+ .

Nitrogen doped carbon quantum dots (NCQDs) of about 10 nm in diameter have been obtained by hydrothermal reaction from collagen. Because of the superiority of water dispersion, low toxicity and ease of functionlization, the NCQDs were designed as a glucose sensor after covalent grafting by 3-aminophenylboronic (APBA) (APBA-NCQDs). The as-prepared APBA-NCQDs were imparted with glucose sensitivity and selectivity from other saccharides via fluorescence (FL) quenching effect at physiological pH and at room temperature, which show high sensitivity and specificity for glucose determination with a wide range from 1 mM to 14 mM. FL quenching mechanism of APBA-NCQDs was also investigated by adding an external quencher. The APBA-NCQDs-based platform is an environmentally friendly way to substitute inorganic quantum dots containing heavy metals which offer a facile and low cost detection method.

Wearable biochemical sensors enabling non-invasive monitoring of biomarkers in bodily fluids play a pivotal role in advancing personalized healthcare. The state-of-the-art wireless and wearable biochemical sensors still suffer from large form factors, poor detection accuracy due to sample-to-sample variation, short and weak wireless communication, and difficulty to integrate with data processing algorithm on a system level. To solve these problems, this work develops an all-range wireless and wearable biochemical sensing platform which can be integrated in a diaper for monitoring four urine biomarkers (dimethylamine, creatinine, glucose, and H + ) with two switchable wireless modes. To simplify the circuit design and reducing the form factor of the wearable sensing platform, this work develops flexible and passive potentiometric sensing interfaces for dimethylamine and creatinine detection by developing high-performance ion-selective electrode (ISE) with customized molecularly imprinted polymers (MIPs) as ionophores. The narrowband Internet of Things (NB-IoT) far-field wireless mode enables remote, and concurrent monitoring of urine biomarkers with a working range up to tens of kilometers, while the LC resonance near-field wireless mode is capable of battery-free and intermittent detection of urine biomarkers. The wearable sensor can be easily switched between the NB-IoT far-field wireless mode and the near-field wireless mode to fit different application scenarios. The wireless sensing platform enables system level integration of the wearable biochemical sensor with a multilayer perceptron data calibration system for data auto-calibration, which reduces the errors caused by varying pH and thus improves the detection accuracy, enabling deeper AI-wearable biochemical sensor fusion for next-generation healthcare applications.

In view of the importance of quantification of beta-amyloid (Aβ), an “aptamer -target- peptide” sandwich electrochemical biosensor to assay Aβ42 was fabricated by using gold–palladium bimetallic nanoparticles covalent organic framework-carbon cloth (Au–Pd@COF TTF-Thi -CC) and prion protein (PrP C ) labeled with horseradish peroxidase (HRP) nanocomposites. The concentration of Aβ42 showed a positive correlation with the peak current resulting from the oxidation of hydroquinone (HQ) by HRP. In contrast, the reference current signal from thionin (Thi), derived from covalent organic framework (COF), showed a negative correlation. The current response of the electrochemical biosensor was proportional to the Aβ concentrations ranging from 0.01 to 2.5 nM with a detection limit (LOD) of 2.17 fM ( S / N = 3). The sensitivity of the sandwich electrochemical biosensor could be primarily amplified based on the substrates of Au–Pd@COF TTF-Thi -CC. The AuNPs and PdNPs not only facilitated the bonding of the linker based on the Au–S bond but also improved the performance of COF TTF-Thi -CC. Secondary sensitivity amplification of the biosensor could be achieved by using PrP C -labeled HRP to catalyze hydroquinone in solution. Furthermore, the biosensor showed excellent selectivity, anti-interference performance, and stability. The Aβ concentrations in cerebrospinal fluid (CSF) were successfully evaluated using the constructed biosensor. This assay provides a potential tool for early-stage Alzheimer's disease diagnosis.
