Near-infrared photoresponsive drug delivery nanosystems for cancer photo-chemotherapy

Journal of Nanobiotechnology, 2020
Drug delivery systems (DDSs) based on nanomaterials have shown a promise for cancer chemotherapy; however, it remains a great challenge to localize on-demand release of anticancer drugs in tumor tissues to improve therapeutic effects and minimize the ...

A photoresponsive glycosidase mimic

Chemical Communications, 2014
Azobenzene-3,3'-dicarboxylic acid exists in photoisomerizable (E) and (Z)-forms. Deprotonation of the carboxylic acid groups from the (E)-form occurs simultaneously, whereas in the (Z)-form it occurs in a stepwise fashion. The mono anionic form of the (Z)-isomer acts as a glycosidase mimic that proceeds through a general acid-general base catalytic ...

Amino-terminated polydimethylsiloxane modified porphyrin for efficiently biphasic photosynthesis of H2O2

Nano Research
Hydrogen peroxide (H2O2) attracts widespread attention as a clean and sustainable oxidant. Nevertheless, porphyrin-based photocatalysts generally exhibit low H2O2 concentration in aqueous systems because the generated H2O2 does not accumulate effectively
