摘要

Rapid formation of silver nanoparticles in matcha tea solution was obtained. Four samples were synthesized at different temperatures (23 °C, 40 °C, 60 °C, and 80 °C) with a 10 mM of AgNO3 in dissolution with 2.5 mg/mL of matcha tea. The most rapid nanoparticle formation was obtained by using 80 °C on the synthesis. In fact, micrographs showed a huge number of nanoparticles with a mean size of 13.5 nm. Nanoparticles presented good activity bactericidal against Escherichia coli.
