Research demonstrates improved antimicrobial efficacy of gold nanoparticles in Escherichia coli and Candida albicans, highlighting the role of cysteine in surface modification.
Key Points
L-cysteine functionalized gold nanoparticles exhibited the highest antimicrobial efficacy against multiple pathogens, including Candida albicans.
The minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) values were lowest for L-Cys-AuNPs, indicating strong antimicrobial action.
Green synthesis techniques using Schinus molle contributed to the eco-friendly production of gold nanoparticles with desirable properties.
Chirality induced by cysteine improved the size uniformity and biological performance of gold nanoparticles.
