Descrição geral

PVP has biocompatibility, low toxicity, adhesive characteristics, complexing stability, relatively inert behavior, and is resistant to thermal degradation. It is readily prepared by the polymerization of N-vinyl-2-pyrrolidone or by the Reppe synthesis technique.

Aplicação

PVP is one of the constituents used in the synthesis and coating of silver nanocubes. It serves as a reducing agent and colloidal stabilizer in the synthesis of palladium nanobars and nanoplates. It is also used as a capping agent in the synthesis of silver nanospheres. General applications of PVP are: in pharmaceutical, food, beverage, cosmetic, toiletry and photographic industries.

New methods for materials fabrication at the micro- and nanoscale will drive scientific and technological advances in areas of materials science, chemistry, physics, and biology. The broad diversity of potentially relevant materials, length scales, and architectures underscores the need for flexible patterning approaches. One important example is the fabrication of 3D periodic structures composed of colloidal, polymeric, or semiconductor5 materials.

Noble-Metal Nanostructures with Controlled Morphologies

Developed in the last several years, fluorescence quenching microscopy (FQM) has enabled rapid, inexpensive, and high-fidelity visualization of two-dimensional (2D) materials such as graphene-based sheets and MoS2.
