The non-biodegradable polymer occupying the world leads to many issues concerning global warming and other related problems. Due these issues, there is a need for biodegradable polymers overcome issues. This paper focussed on processing polyvinylalcohol (PVA) crosslinked with glutaraldehyde(GA) studying harness of polymer. from 0 40 volume percent glutaraldehyde than post cured immersed in 2 mo...

Background: Infection control is a major issue in medicine and dentistry because of concern over communicable diseases transmitted health care settings. The present study was conducted for comparatively evaluating various Cold Sterilization Techniques on Carbide Burs Diamond Points. Materials & methods: Two disinfectant solutions were used: 2% glutaraldehyde 5.2% sodium hypochlorite. group ...

BACKGROUND AND AIM: Proper disinfection of impression is probably the most important procedure for dental lab to render it safe further handling without affecting accuracy fine details. In light these intermingling facts, author aimed 1) investigate antimicrobial effect Cymbopogon citratus on selected microorganism colony and 2) disinfectant solution dimensional resultant gypsum casts. MATERIAL...

Abstract In the work, possibility of using nanoparticles gold (AuNPs) to upgrade bioselective elements biosensors in order improve their analytical characteristics is considered. The based on acetylcholinesterase (AChE), butyryl cholinesterase (BuChE) and glucose oxidase (GOD) were used as an experimental model. Immobilization enzymes surfaces conductometric transducers was performed by crossli...

Cryogelation has become an advantageous method to obtain macro-porous materials with well-defined, interconnected pores for tissue engineering applications. Herein, polyvinyl alcohol and chitosan polymers (PVA-CHI) were used produce cryogel scaffolds via cryogelation. Glutaraldehyde was as a crosslinking agent the effect of amount on properties investigated. divided into 5, 10, 15% total polyme...

entrapment of permeabilized whole cells within a matrix is a common method for immobilization. chitosan possesses distinct chemical and biological properties, which make it a suitable matrix for entrapment and immobilization of penicillin g acylase (pga). in the first step, escherichia coli (atcc 11105) cells were permeabilized using n-cetyl-n,n,n-trimethyl ammonium bromide (ctab) (0.1% w/v, 45...
