Stability and Biocompatibility Tests of Alginate as Cochlear Implant Coating Material [PDF]

Current Directions in Biomedical Engineering, 2021
Abstract Inner ear trauma caused by cochlear implantation is a severe clinical problem. It was shown that an electrode alginate coating can reduce the insertion forces in vitro. The grade of the alginate viscosity can be adjusted by using different metal ions for cross-linking the salts of the alginic acid. The aim was to investigate the

Biocompatible Carbon-Based Coating as Potential Endovascular Material for Stent Surface [PDF]

BioMed Research International, 2018
Stainless steel 316L is a material commonly used in cardiovascular medicine. Despite the various methods applied in stent production, the rates of in-stent restenosis and thrombosis remain high. In this study graphene was used to coat the surface of 316L substrate for enhanced bio- and hemocompatibility of the substrate. The presence of graphene layers
