The aggregation of silver nanoparticles (AgNPs) in colloidal solution and the oxidative cytotoxicity towards human cells are two major hindrances for their thriving medicinal applications. Their incorporation natural polymers such as cellulose, chitosan, alginate, collagen, gelatin, silk fibroin, carrageenan, curdlan, hyaluronic acid, keratin starch may be an alluring alternative strategy to si...

in this study, the effect of gelatin-chitosan edible coating on the quality of chicken breast during 9 days of refrigerated storage (4 was investigated. three concentrations of gelatin (3, 6 and 8% w/v) and two concentrations of chitosan (1 and 2% w/v) were used to prepare the coating materials. samples was divided in 7 group, no coating (control), gelatin 3% and chitosan 1% (sample 2), gelatin...

Pseudomonas aeruginosa is an opportunistic pathogen that causes a variety of infections in compromised patients. The ability of Pseudomonas aeruginosa to produce chronic infection is based in part on its ability to biosynthesis of biofilm, and alginate is the major polysaccharide in the synthesized biofilm. So alginate degradation is very essential in the dispersion of Pseudomonas aeruginosa bi...

Plant polyphenol compounds have been considered nutritionally important recently. However, achieving successful delivery of flavonoids and phytoestrogens via the oral route is particularly difficult, due to the formiable enzymatic and transport barriers in the gastrointestinal tract. Polymer-based delivery systems that trap molecules of interest within networks have been develpoed extensively f...

Biomaterials are being extensively used in regenerative medicine including tissue engineering applications, as these enhance development, repair, and help the process of angiogenesis. Wound healing is a crucial biological regeneration ruptured after getting injury to skin other soft humans animals. Besides, accumulation microbial biofilms around wound surface can increase risk physically obstru...

Tissue-adhesive materials are emerging biomaterials with potential applications in wound healing patches, tissue sealants, and haemostat materials. Tissue adhesives based on synthetic polymers generally have good adhesion but not biodegradable. However, the long-term presence of non-biodegradable body can cause secondary harm to patient. An ideal adhesive should meet following requirements: adh...

Background: Alginate is a linear polysaccharide consisting of guluronate (polyG) and mannuronate (polyM) subunits. Methods: In the initial screening of alginate-degrading bacteria from soil, 10 isolates were able to grow on minimal medium containing alginate. The optimization of cell growth and alginate lyase (algL) production was carried out by the addition of 0.8% alginate and 0.2-0.3 M NaCl ...

Background and Objective: The opportunistic pathogen Pseudomonas aeruginosa secrets a capsule-like polysaccharide called alginate which is important for evasion of host defenses, especially in patients with suppressed immunity. Method of alginate determination has an important role in the study of microb...

Gelatin was extracted from hydrolyses of collagen muscle bonds. Gelatin was of two types. Type A was obtained from acidic and type B from alkaline procedures. In the present study we used sturgeon fish skin to produce 25 samples of gelatin. Microbiological and chemical examinations were conducted on the gelatin samples. Based on the results obtained from the chemical examination, gelatin type A...

New catalytic materials, based on palladium immobilized in ionic liquid supported on alginate, were elaborated. Alginate was associated with gelatin for the immobilization of ionic liquids (ILs) and the binding of palladium. These catalytic materials were designed in the form of highly porous monoliths (HPMs), in order to be used in a column reactor. The catalytic materials were tested for the ...
