Modification to surface texture of biomaterials, protein adsorption and interactions of biomaterials and cells have been studied in vitro for several decades in tissue engineering. However, few reports focus on the decoration of in vivo environment to implanted biomaterials and the effects of the decoration on cells proliferation and wound healing. In this study, we used porous silk fibroin materials...
A novel nano Fe3O4-Au modified amperometric immunosensor for rapid separation-free determination of human immunodeficiency virus (HIV) p24 antigen in acquired immunodeficiency syndrome (AEDs) patients' serum is proposed. Firstly, one novel sebacato-bridged Cu(II) phen complex Cu(phen)L2 (referred to as CuL, H2L=sebacic acid; phen=1,10phenanthroline) was absorbed on the surface of glassy carbon electrode...
Novel membranes were prepared through covalently coupling of chitosan (CS) to activate nylon membrane after the reaction of the microporous nylon membrane with formaldehyde. Non-specific adsorption on the CS-coated nylon membrane decreased greatly. Yellow 3G-P/Reactive Red 120 were then covalently immobilized onto composite membrane as dye ligands. These Red 120/Yellow 3G-P-CS-membranes were used...
Natural zeolites are bioactive materials. They have different applications; they are used as additives in animal feeds to support biomass production and used to treat stomach ulcers incisions in humans as they act as buffers to reduce stomach acidity. Based on different health applications, structural stability of zeolite during digestion is important to understand possible interactions, positive...
Electrospun poly (L-lactic acid) (PLLA) and poly (L-lactide -co -glycolide) (PLGA) mats were fabricated as wound dressings. The in vitro degradation behavior was studied in phosphate buffer solution (PBS, pH 7.4) at 37degC for 6 days. Structural and morphological changes during degradation were investigated with gel permeation chromatography (GPC) and scanning electron microscopy (SEM). Both of the...
