Chitosan-based synthesis of magnetically-driven nanocomposites with biogenic magnetite core, controlled silver size, and high antimicrobial activity

Original language description

We report a new procedure, exploiting "green" chemistry, resulting in biocompatible magnetically-driven nanocomposites with high antibacterial and antifungal activities against ten tested bacterial strains and four Candida species. The nanocomposites consist of silver nanoparticles (NPs), biogenic magnetite NPs isolated from magnetotactic bacteria, and an environmentally friendly polymer - chitosan. These hybrids were prepared using an acidified chitosan suspension to cover biogenic magnetite NPs by a cross-linking method, followed by employing the NH2 groups of chitosan for the reduction of silver salt in an alkaline medium. Thus, in the procedure, chitosan acts as (i) a biocompatible matrix surrounding the magnetite NPs, (ii) a reducing agent for thesilver ions, and (iii) a linker between magnetic and silver NPs. The size of the resulting silver NPs and the total amount of silver involved in the nanocomposites can be simply controlled by the initial concentration of the silver salt
