Abstract

Chemical synthetic method in synthesizing silver nanoparticle was quite expensive, toxic and flammable. In order to enhance green technology, we develop a simple biological method for the green synthesis of silver nanoparticles using two lichens species, Parmotrema praesorediosum and Ramalina dumeticola. Silver nanoparticles were characterized using UV-Vis absorption spectroscopy and TEM. Within 72 hours reaction time, absorption spectra of silver nanoparticles formed in R. dumeticola and P. praesorediosum has absorbance peak at 407 nm and 423 nm, respectively. TEM analysis showed the average size of 20 nm of silver nanoparticles obtained in R. dumeticola and the average size of 42 nm of silver nanoparticles obtained in P. praesorediosum. These two lichens species are able to synthesize silver nanoparticles through green chemistry method, which are environmental friendly and cost effective. This is for the first time that any species of lichens was used for the synthesis of silver nanoparticles.
