The real-time temperature of Ag2S PTT was monitored through a non-contact upconversion thermometer in a composite structure

Sesame ball-like PTT nanoplatforms with fluorescence-background-free temperature sensing

“…7,[18][19][20] Among them, Ag 2 S nanoparticles are promising candidates for PTAs because of their low toxicity, low solubility constant (K sp = 6.3 Â 10 À50 ), high photothermal conversion efficiency, and good physical and chemical properties. [21][22][23] For example, Wu et al prepared graphene oxide/Ag 2 S (GO/Ag 2 S) heterostructures, which showed good bactericidal properties (against E. coli and S. aureus), and confirmed their PTT sterilization effect using a subcutaneous abscess model. 24 However, during the treatment of bacterial infections, there remain unsolved issues regarding real-time temperature monitoring, which is used to avoid excessively high temperature causing damage to healthy tissue.…”
