Electrospun nanofibers for Sustained Delivery of Cetylpyridinium Chloride for Buccal Topical Application

Zanin M.H.A., Santos V.A., Oliveira A.M., Cerize N.N.P., Borsatti M.A., Institute for Technological Research of the State of São Paulo - IPT, BR

The aim of this study was to prepare electrospun polymeric nanofiber mat composed of polyvinylpyrrolidone (PVP-Kollidon® 90F), ammonio methacrylate copolymer type B (PMMA-Eudragit® RS100) and cetylpyridinium chloride (CPC), 10:10:1 (wt/wt%) and its characterization for buccal [...]

Synthesis of {111}-faceted Au Nanocrystals Mediated by Polyvinylpyrrolidone: Insights from Density-Functional Theory and Molecular Dynamics

Liu S.-H., Saidi W.A., Zhou Y., Fichthorn K.A., The Pennsylvania State University, US

We use dispersion-corrected density-functional theory (DFT) and classical molecular-dynamics (MD) to resolve the role of polyvinylpyrrolidone (PVP), a widely used structure-directing agent, in the shape-selective synthesis of {111}-faceted Au nanostructures. First by DFT, we consider [...]

Electrospun 5-fluorouracil loaded bovine serum albumin-polyvinylpyrrolidone nanofibers

Illangakoon U.E., Chatterton N.P., Williams G.R., Nazir T., London Metropolitan University, UK

5-FU loaded bovine serum albumin (BSA)/ polyvinylpyrrolidone (PVP) nanofibers prepared using an electrospinning process. The nanofibers were characterised by scanning electron microscopy (SEM) energy - dispersion spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction [...]
