Biomedical applications of shape memory polymers (SMPs) are limited by their biostability, degradability, and possible toxicity risks after implantation. Mesoporous silica nanoparticles (MSNs) were used to increase the oxidative biostability (increase time until degradation occurs) using antioxidants and to induce oxidative degradation through incorporation of hydrogen peroxide-containing MSNs with modified surfaces. The presented results confirm increased oxidative stability using antioxidants, [...]

Background:Diabetic patients suffer from chronic wounds partly due to altered function of fibroblasts. Fibroblasts of diabetic patients synthesize collagen I (COLI) at a much higher level than collagen III (COLIII), resulting in delayed tissue granulation and, consequently, a delay in the overall wound healing process. Methods:We aimed to revive the matrix protein productivity of diabetic [...]

Increasing interest in bacterial cellulose due to the huge potential which exists for the development of this new biomaterial for medical applications has been met with recent growth in research in engineering this unique microbial manufactured material. The mechanical properties, porosity, and biocompatibility of bacterial cellulose derived biomaterials are particularly attractive for use in wound healing, tissue engineering, and drug delivery applications. Advances in synthetic biology and sof [...]

Tin telluride (SnTe) ultrathin films were deposited electrochemically on polycrystalline and monocrystalline gold substrates using the electrochemical atomic layer epitaxy (ECALE) method. The electrochemical behaviors of Sn and Te were studied systematically by means of cyclic voltammetry. Cyclic voltammetry curves for Sn displayed a broad peak in the region between -0.15 V and -0.35 V, which was related to the under-potential deposition (UPD), while the curves for Te displayed a peak at 0.3 V f [...]

Background:Wound management is an important field in medical care, as annually, millions of wounds require treatment worldwide. Soy protein is highly biocompatible, easily processed, and a relatively cheap natural polymer, which can be used for wound dressing applications. Methods:In this study, solvent cast soy protein films, plasticized by glycerol and cross-linked by glyoxal, were therm [...]
