A near-infrared light-responsive multifunctional nanocomposite hydrogel for efficient and synergistic antibacterial wound therapy and healing promotion.

The development of new multi-functional dressing materials that effectively combine excellent antibacterial and wound healing promotion properties are highly desirable in modern biomedical research and clinical practice. In this study, a new near-infrared photo-responsive dressing material (HG1-CW) was fabricated based on a dodecyl-modified and Schiff base-linked chitosan hydrogel, a photothermal agent (WS2 nanosheets), and an antimicrobial drug (ciprofloxacin). This nanocomposite dressing possesses the advantages of being injectable, self-adapting, rapidly molding, and has good tissue adherence and excellent biocompatibility.

Metal coordination polymer induced perylene probe excimer fluorescence and its application in acetylcholinesterase sensing and alpha-fetoprotein immunoassay.

A novel sensing strategy for acetylcholinesterase (AChE) and alpha-fetoprotein (AFP) is developed, based on the perylene probe monomer to excimer fluorescence transformation induced by the in situ generation of a metal coordination polymer. In the presence of AChE, acetylthiocholine chloride was hydrolyzed to thiocholine. Ag and the produced thiocholine formed a positively charged metal coordination polymer, which induced the aggregation of a negatively charged perylene probe and the formation of probe excimer emission.

A smart perylene derived photosensitizer for lysosome-targeted and self-assessed photodynamic therapy.

A perylene probe PC4 is explored as a smart lysosome-targeted photosensitizer. It can efficiently kill cancer cells and also mark dead cells with bright fluorescence emission in nuclei for real-time monitoring and assessing of the photodynamic therapeutic efficiency.

Aggregation enhanced excimer emission (AEEE) of benzo[ghi]perylene and coronene: multimode probes for facile monitoring and direct visualization of micelle transition.

We report benzo[ghi]perylene (BzP) and coronene (Cron) as multimode fluorescent probes for accurate monitoring and direct visualization of monomer-micelle transitions in surfactants for the first time. The probe molecules formed self-assembled nanoparticles in an aqueous solution and displayed strong aggregation-enhanced excimer emission (AEEE). During the process of surfactant monomer-micelle transition, the probe nanoparticles dissolved, and the observation of excimer-monomer emission transition clearly indicated the formation of micelles.
