Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer compound made from the monomer N-vinylpyrrolidone. [1] PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties.
Percoll itself specifically consists of polydisperse silica nanoparticles 15–30 nm diameter (23% w/w in water) which have been coated with polyvinylpyrrolidone (PVP). Percoll is well suited for density gradient experiments because it possesses a low viscosity compared to alternatives, a low osmolarity , and no toxicity towards cells and their ...
Povidone-iodine is a chemical complex of the polymer povidone (polyvinylpyrrolidone, PVP) and triiodide (I − 3). [24] It is synthesized by mixing the PVP polymer with iodine (I 2), allowing the two to react. [25] It is soluble in cold and mild-warm water, ethyl alcohol, isopropyl alcohol, polyethylene glycol, and glycerol.
Commonly referred to as bird flu, it’s a highly contagious viral disease affecting domestic poultry, wild birds, and, in some cases, mammals … including humans. The recent rise in Avian ...
A fatal virus has been discovered in shrews in Alabama, sparking concerns about potential contagion to humans. The Camp Hill virus was discovered by researchers at The University of Queensland.
N-Vinylpyrrolidone (NVP) is an organic compound consisting of a 5-membered lactam ring linked to a (2 carbon) vinyl group.It is a colorless liquid although commercial samples can appear yellowish.
Chrissy Teigen is indulging in some skincare self-care.. On Thursday, Jan. 30, the model and cookbook author, 39, shared an Instagram Stories clip of herself looking unrecognizable as she sported ...
Polyvinylpolypyrrolidone (polyvinyl polypyrrolidone, PVPP, crospovidone, crospolividone, or E1202) is a highly cross-linked modification of polyvinylpyrrolidone (PVP).. The cross-linked form of PVP is used as a disintegrant (see also excipients) in pharmaceutical tablets. [1]
