Abstract
The present study was aimed to carry out a green synthesis of Silver Nano Particless by using marine micro algae and its characterization by SEM, EDAX, Particle analyzer and Zeta potential. Microalgae samples (Isochrysis galbana and Nannochloropsis sp.) were collected from phytoplankton laboratory, Tuticorin Research Centre of ICAR-Central Marine Fisheries Research Institute. The culture media of I. galbana and Nannochloropsis sp. were taken for the preliminary synthesis of SNPs. Hence, Nannochloropsis sp. was not synthesized for its SNPs, I. galbana was selected for further study. Culture media, cell filtrate and supernatant of I. galbana were subjected to the SNPs synthesis in order to find out the maximum yield of silver with low chloride content. Among these, the supernatant of I. galbana showed maximum yield with low chloride content. It was confirmed by colorimetric reading at 450 nm. Synthesized SNPs from I. galbana contained 80.68% of silver and 15.25% of chloride as detected by EDAX analysis. Size of the SNPs was analyzed by particle analyzer and ranged from 16.6 to 205.3 nm and average size was 40.6 nm. Zeta potential of SNPs from I. galbana was -44.0 mV, which reveals the high stability of SNPs. This is the first authenticated work of I. galbana with respect to complete characterization of its SNPs.
