Chitosan-silver nanoparticles (Ch-AgNPs) are hybrid nanostructures where silver nanoparticles are stabilized and functionalized by chitosan, a biodegradable and biocompatible polysaccharide. The Ch-AgNPs production service at CD BioGlyco offers advanced, eco-friendly solutions for synthesizing high-quality Ch-AgNPs. Chitosan acts as both a reducing and stabilizing agent, preventing aggregation and enhancing stability while maintaining biocompatibility. Based on our techniques like chemical reduction and green synthesis, our service ensures the high-quality and custom-amount production of nanoparticles.
Our GlycoNano™ Platform offers advanced Glyconanoparticle Development Services and several Techniques for Glyconanoparticle Development. We use methods such as chemical reduction, green synthesis, and sonication. These techniques are integrated into the development process to deliver stable, scalable, and highly effective glyconanoparticles for research and industrial use.
The production of Ch-AgNPs consists of two main steps: first, producing chitosan spheres (Chi-spheres), followed by incorporating silver nanoparticles to form composite structures (AgNPs-Chi-Spheres).

Results: This research investigated the production of AgNPs-Chi-Spheres, utilizing chitosan as a stabilizer and NaOH as a reducing agent, with NaOH concentrations varying between 20% and 50%. The resulting nanoparticles were characterized using various techniques, including UV-Vis spectroscopy, which confirmed surface plasmon resonance at 410 nm; FTIR and XRD analyses, which identified functional groups and crystalline structure; and SEM-EDX, which revealed smooth, spherical, and nonporous particles, with the smallest size of 46.91 nm at 20% NaOH. Zetasizer nano analysis showed good colloidal stability with high zeta potential values. At the same time, antimicrobial tests demonstrated broad-spectrum efficacy, with the highest inhibition zones observed at 50% NaOH against S. aureus (19.5 mm), E. coli (18.56 mm), and C. albicans (12.25 mm). The findings highlight AgNPs-Chi-Spheres as promising antimicrobial agents with stable and tunable properties.
