Gold nanostructures were fabricated in porous SiO2/Si ion-track templates by the wet chemical deposition from a solution of Au(I) sulfite complex. Their morphological features were analyzed, and features of the deposition processes were determined. A mechanism describing the selective formation of gold nanostructures in the pores of SiO2 was proposed. The present approach allows us to control shape and size of Au nanostructures those which can be used as plasmonic active surfaces for SERS detecting of small amounts of biological and chemical substances.

Abstract Au@Ag nanoparticles decorated on cellulose paper could be worthful biomedical applications. Electrospinning technique is broadly employed for fabrication of nano and micro size fibers with a variety of biopolymers adding cellulose acetate nanofibers. Evolutions in cellulose research demonstrate that it is an anticipating material for the biomedical application. Nanofibers acquired by electrospinning technique were utilized in various biomedical applications. In this report, electrospinning of cellulose acetate, the solvent choice for cellulose acetate e-spun nanofabrication and decoration of AgNPs including shape and size for antimicrobial activity are argued.

Lanthanide-doped upconversion nanoparticles have emerged as attractive candidates for biomedical applications. This is due to their excitation and emission wavelengths, which lay the foundation for deeper penetration depth into biological tissue, higher resolution due to reduced scattering and improved imaging contrast as a result of a decrease in autofluorescence background. Usually, their encapsulation within a biocompatible silica shell is a requirement for their dispersion within complex media or for further functionalization of the upconversion nanoparticle surface. However, the creation of a silica shell around upconversion nanoparticles can be often challenging, many times resulting in partial silica coating or nanoparticle aggregation, as well as the production of a large number of silica particles as a side product. In this work we demonstrate a method to accurately predict the experimental conditions required to form a high yield of silica-coated upconversion nanoparticles, regardless of their shape and size.
