Biocompatible hydroxyapatite nanocomposites are biocompatible, biodegradable and nontoxic have been paid many attentions as one of the most suitable vehicle for drug delivery use. Our objective in this work was to prepare and characterize caseins based HA nanocomposite in a colloidal form for drug delivery purposes. Casein biopolymer was firstly extracted from skimmed milk by adding acetic acid...

BACKGROUND: Biotechnology applications of magnetic gels include biosensors, targeted drug delivery, artificial muscles and magnetic buckles. These gels are produced by incorporating magnetic materials in the polymer composites. METHODS: A biocompatible magnetic gel film has been synthesized using polyvinyl alcohol. The magnetic gel was dried to generate a biocompatible magnetic film. Nanosized ...

An aqueous sol-gel route has been developed for electrochemically controlled deposition onto micro and nanofabricated electrodes. TEOS and MeTEOS were hydrolyzed under acidic conditions, and alcohol products were removed by distillation. The resulting clear sol has a hydrolysis ratio between 40 and 45. Following hydrolysis, pH was raised to 5.0 with addition of potassium hydroxide. At room temp...

A microelectromechanical systems (MEMS) thermal flow sensing array constructed of biocompatible materials has been designed, fabricated, nd tested. In addition to the construction, the electronic biasing conditions were selected such that sensor operation was compatible with biological uids. The device comprises several thin film platinum sensing elements sandwiched in a Parylene C membrane. Th...
