Optical confinement of a laser radiation in the 3.8–4.2 μm range in a composite material containing silver nanoparticles

In this paper studies of the changes of the morphology of silver colloidal nanoparticles under laser irradiation at different fluences and wavelengths have been presented. Silver nanoparticles of size 10-30 nm were prepared in a gelatin stabilized AgNO3 solution under reduction with K-Na-tartrate. They were then exposed to pulsed laser radiation at 532 nm, 400 nm and 266 nm. In addition to the fragmented particles, relatively larger-size (1400-1500 nm) rightangled structures were found to be formed in the solution. The experimental conditions favouring laser-induced transformation of the morphology of nanoparticles have been determined.

Chitin, as one of nature’s most abundant structural polysaccharides, possesses worldwide, high industrial potential and a functionality that is topically pertinent. Nowadays, the metallization of naturally predesigned, 3D chitinous scaffolds originating from marine sponges is drawing focused attention. These invertebrates represent a unique, renewable source of specialized chitin due to their ability to grow under marine farming conditions. In this study, the development of composite material in the form of 3D chitin-based skeletal scaffolds covered with silver nanoparticles (AgNPs) and Ag-bromide is described for the first time. Additionally, the antibacterial properties of the obtained materials and their possible applications as a water filtration system are also investigated.
