چکیده
Bioactive materials of natural origin have great demand in industry and medicine due to their versatility useful properties. The main purpose this work is prepare biocomposites for the dual modified silk fibroin (Bombyx mori L.), which protects against destructive effects bioactive, antioxidant ultraviolet rays. For purpose, an aqueous extract autumn leaves anthocyanin-rich smoke tree plant (Cotinus coggygria L.) was applied. 2% thiourea solution used increase durability SF external influences use textiles. intensity free radicals fibroin-anthocyanin (SFA) fibroin-anthocyanin-thiourea (SFAT) by Electron Paramagnetic Resonance (EPR) method studied. Maximum adsorption time determined 20 minutes SFA bio-composite 80-85% SFAT biocomposite 50-55% relation untreated. biomedical SFA, radical scavenger activity kinetics were studied on a UV-2700 spectrophotometer capture calculated: RSA% (bioextract) = 73.52 ± 0.5, (SF) 6.42 0.4, 45.23 0.8

Silk Fibroin Based Porous Materials
Silk from the Bombyx mori silkworm is a protein-based fiber. Bombyx mori silk fibroin (SF) is one of the most important candidates for biomedical porous material based on its superior machinability, biocompatibility, biodegradation, bioresorbability, and so on. In this paper, we have reviewed the key features of SF. Moreover we have focused on the morphous, technical processing, and biocompatib...
متن کاملMicrowave Saturation of Complex EPR Spectra and Free Radicals of Burnt Skin Treated with Apitherapeutic Agent
The effect of microwave power on the complex electron paramagnetic resonance spectra of the burn matrix after the therapy with propolis was examined. The spectra were measured with microwaves in the range of 2.2-79 mW. Three groups of free radicals were found in the damaged skin samples. Their spectral lines evolve differently with the microwave power. In order to detect these free radical grou...
