OPTIMASI KONSENTRASI L-Cysteine PADA MODIFIKASI SINTESIS NANOPARTIKEL PERAK (AgNPs) DENGAN L-Cysteine

Abstract

Modification of Synthesis of Nanoparticles with L-Cysteine ​​functions as a capping agent/stabilizer, so that the nanoparticles can last longer. Modification of nanoparticle synthesis by adding L-Cysteine ​​to AgNPs and homogenizing it using a magnetic stirrer. Modification of nanoparticles (silverAgNPs) was monitored by observing the visible uptake. The results showed that the absorbance value increased by indicating the concentration of L-cysteine ​​5x10­^-5; 6x10^-5; 7x10^-5; 8x10^-5; 9x10^-5; 1x10^-4 and the volume of L-cysteine ​​is 4 mL.
