Advanced Healthcare Materials, EarlyView.TOC represents the synthesis of theory‐guided novel near‐infrared (NIR) light‐absorbing organic photosensitizers (OPS) enabling redox‐induced tumor phototherapy and single‐cell organelle tracking. ABSTRACT The design of organic photosensitizers that operate efficiently in the near‐infrared (NIR) region remains challenging due to the need to balance ...

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy
Advanced Materials, EarlyView.Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Reactivation of Serratia marcescens Endonuclease NucSma(H89G) by Hydroxilamine [PDF]
Учёные записки Казанского университета: Серия Естественные науки, 2017 Serratia marcescens endonuclease is the most nonspecific nuclease known. This nuclease refers to enzymes that can cleave both DNA and RNA. The active site of this enzyme is characterized by the H–N–H motif, but more important functions have been shown ...

Advanced Materials, EarlyView.Controlling the protein corona formation onto carbon nanomaterials (CNMs) enhances their functionalities as platforms for cancer theranostics. Here, we reviewed the effects of the intrinsic and acquired properties of CNMs on protein corona formation, the consequent biological and toxicological outcomes, and the strategies to reshape corona formation ...
