Silver nanoparticles (AgNPs) are nanometric-scale structures widely applicable across numerous fields owing to their unique properties. Their synthesis typically has a bottom-up approach via chemical reduction reactions using agents such as sodium citrate and ascorbic acid to yield stable colloids. In this process, various factors affect the particle nucleation and growth which define their final characteristics. Sodium citrate also acts as a stabilizing agent, while ascorbic acid provides an eco-friendly and effective route for AgNP production. These nanoparticles exhibit pronounced antimicrobial activity against a wide spectrum of microorganisms, including bacteria, fungi, and viruses. This chapter presents the synthesis of AgNPs using sodium citrate and ascorbic acid, their characterization, and the results of antimicrobial assay of the nanoparticles both in solution and when incorporated into water-based paint.

摘要

Silver nanoparticles (AgNPs) are nanometric-scale structures widely applicable across numerous fields owing to their unique properties. Their synthesis typically has a bottom-up approach via chemical reduction reactions using agents such as sodium citrate and ascorbic acid to yield stable colloids. In this process, various factors affect the particle nucleation and growth which define their final characteristics. Sodium citrate also acts as a stabilizing agent, while ascorbic acid provides an eco-friendly and effective route for AgNP production. These nanoparticles exhibit pronounced antimicrobial activity against a wide spectrum of microorganisms, including bacteria, fungi, and viruses. This chapter presents the synthesis of AgNPs using sodium citrate and ascorbic acid, their characterization, and the results of antimicrobial assay of the nanoparticles both in solution and when incorporated into water-based paint.
