(182)Crystallinity of Polyvinylalcohol. II.

Photo-reactive polyvinylalcohol for photo-immobilized microarray.

A new photo-reactive polymer, polyvinylalcohol modified with phenylazido groups, was synthesized as a microarray matrix. The polymer is soluble in water and spin-coated onto glass plate. Aqueous solutions of proteins were micro-spotted onto the coated glass and were fixed by ultraviolet light irradiation. Subsequently, cell adhesion on the photo-immobilized protein microarray was investigated. ...

Investigation on the Effect of Microwave Field on the Rheological Behavior of Polyaniline: Polyvinylalcohol Blends

Direct Electrochemistry of Hemoglobin Immobilized in Polyvinylalcohol and Clay Composite Film Modified Carbon Ionic Liquid Electrode

Neste trabalho, líquido iônico hexaflúor-fosfato de 1-butil-3-metilimidazólio (BMIMPF6), em temperatura ambiente, foi usado como ligante na fabricação de um eletrodo líquido iônico de carbono (CILE). Hemoglobina (Hb) foi imobilizada na superfície de CILE com argila e um filme composto por polivinil álcool (PVA) pelo método camada por camada. Espectros de UV-Vis e FT-IR mostraram que Hb no filme...

Removal of low density lipoprotein from blood plasma using cross-linked, sulfated polyvinylalcohol.

The properties of a new synthetic LDL binding material, consisting of fragments of loosely crosslinked hydrogel, based on sulfated polyvinylalcohol are described. When incubated with 20 times its volume of plasma, this material binds up to 95% of the LDL, even from plasma with severely elevated LDL cholesterol levels (up to 20 mM). In addition a cholesterol-rich subfraction of VLDL is bound but...

A Novel Vitreous Substitute of Using a Foldable Capsular Vitreous Body Injected with Polyvinylalcohol Hydrogel

Hydrogels may be the ideal vitreous substitutes due to their wonderful physical features and biocompatibility. However, their drawbacks, short residence time, and biodegradation in vivo, have led to the fact that none of them have been approved for clinical use. In this study, we developed a novel approach of using a foldable capsular vitreous body (FCVB) injected with polyvinylalcohol (PVA) hy...
