Catch-and-Release Probes Applied to Semi-Intact Cells Reveal Ubiquitin-Specific Protease Expression in Chlamydia trachomatis Infection.
Protein ubiquitylation controls many cellular pathways, and timely removal of ubiquitin by deubiquitylating enzymes (DUBs) is essential to govern these different functions. To map endogenous expressio...Read More
Photothermally responsive supramolecular polymers containing azobenzene units have been synthesised and employed as dispersants for multi-walled carbon nanotubes (MWCNTs) in organic solvents. Upon tri...Read More
We show that diamagnetic particles can be remotely manipulated by a magnet by the reversible adsorption of dual-responsive, light-switchable/superparamagnetic nanoparticles down to their surface. Adso...Read More
Photoreversible switching of the lower critical solution temperature in a photoresponsive host-guest system of pillararene with triethylene oxide substituents and an azobenzene derivative.
A new water-soluble thermoresponsive pillararene with triethylene oxide groups was synthesized. The pillararene showed lower critical solution temperature behavior in aqueous solution. Its cloud...Read More
Fastest thermal isomerization of an azobenzene for nanosecond photoswitching applications under physiological conditions.
When speed is of the essence: After photoisomerization to its metastable cis form, an azo dye must undergo fast thermal isomerization back to the trans form to be suitable for real-time information tr...Read More
We report a precise control over the hierarchy levels in the outstanding self-organization process shown by chiral azobenzene dimer 1. This compound forms uniform toroidal nanostructures that can hier...Read More
