Photosensitizer–AgNP composite with an ability to selectively recognize pathogen and enhanced photodynamic efficiency.

BODIPY-functionalized glycopolymer-modified AgNPs were prepared as a PDT agent. The agent was “smart”, i.e., it could distinguish pathogens from normal cells, and showed a photodynamic efficiency three times greater than that of free photosensitizer under the same light intensity. The work is a good attempt to make a new generation of PDT agents for antibacterial applications. [ABSTRACT FROM AUTHOR]
