Tea extracts boost silver nanoparticles' antimicrobial power against pathogens

Researchers at the Institute of Physical Chemistry of the Polish Academy of Sciences have developed green tea-silver nanoparticles that exhibit powerful antimicrobial activity against bacteria and yeast. The hybrid nanoparticles, synthesized using tea extracts as a capping agent, showed higher antibacterial and antifungal properties compared to silver nanoparticles alone. The nanoparticles were effective against ESKAPE bacteria and problematic yeast pathogens, reducing the number of bacterial and fungal cells. The combination of tea extracts and silver nanoparticles could potentially be used as an alternative to antibiotics in combating infections, with lower dosages required. The researchers aim to further explore the applications of these nanoparticles in agriculture and biomedical fields.
