New biodegradable network polymers containing siloxane-linked polymeric prodrugs of 5-ammino-2-hydroxybenzoic acid (5-ASA) in the main chain were prepared by ter polymerization of methacrylic acid (MA), 2-hydroxyethylmethacrylate (HEMA), and bis (trimethylsilyloxy) methylsilane (VBM) in the presence of some new cross-linking agents.The monomers and polymers were characterized by FT-IR and 1H-NM...

Composites based on waste products from the production of 5-hydroxymethylfurfural - "humins" and melamine or urea (as a cross-linking agent) with wood fl our filler, 70 % by weight) were obtained. Studies physical mechanical properties materials different contents have been carried out, which shown that composites humins: (2,5: 1) humins:urea (2:1) tensile strength 150 165 MPa, respectively, si...

Abstract Background Nanoparticulate drug delivery systems have attracted significant attention in the field of cancer nanotechnology. This study determines the effect of folate-based Fe2O3 nanoparticles. This study aimed to decorate nanoparticles with folate (FA), a molecular ligand for ‘active’ targeting of cancerous cells and the application of modified-nanoparticles in cancer treatment. ...

Collagen and elastin are the main structural proteins in mammal bodies. They provide mechanical support, strength, and elasticity to various organs and tissues, e.g. skin, tendons, arteries, and bones. They are readily available, biodegradable, biocompatible and they stimulate cell growth. The physicochemical properties of collagen and elastin-based materials can be modified by cross-linking. G...

The magnetic hydrogels were successfully fabricated by chemically cross-linking of gelatin hydrogels and Fe3O4 nanoparticles (ca. 40–60 nm) through genipin (GP) as cross-linking agent. The cross-sectional SEM observation demonstrates that the Fe3O4 nanoparticles were fairly uniformly distributed in the gelatin matrix. Moreover, in vitro release data reveal that drug release profile of the resul...
