Composite polymer/wax coatings as a corrosion barrier of bioresorbable magnesium coronary stents.

Magnesium and its alloys are suitable materials for biodegradable biomedical implants such as cardiovascular stents. Here we introduce an innovative composite polyelectrolyte multilayer/wax coating applied to commercial coronary Mg-based stents serving as a barrier layer effectively retarding corrosion. This hydrophobic coating, build by layer-by-layer technology, appeared very thin, smooth, homogeneous, strongly adherent and completely covering the surface of the Mg-stent.

Data on mechanical properties of open-cell AlSi10Mg materials and open-cell AlSi10Mg-SiC composites with different pore sizes and strain rates.

This data article describes the stress-strain curves, energy absorption and energy absorption efficiency of open-cell AlSi10Mg materials and open-cell AlSi10Mg-SiC composites with different pore sizes and strain rates. The data were obtained by quasi-static compression loading up to 60% strain at strain rates of 0.01 and 0.

Suitability of Jellyfish-Collagen-Coated Well Plates for Cytocompatibility Analyses of Biomaterials.

Cytocompatibility analyses of new implant materials or biomaterials are not only prescribed by the Medical Device Regulation (MDR), as defined in the DIN ISO Norm 10993-5 and -12, but are also increasingly replacing animal testing. In this context, jellyfish collagen has already been established as an alternative to mammalian collagen in different cell culture conditions, but a lack of knowledge exists about its applicability for cytocompatibility analyses of biomaterials. Thus, the present study was conducted to compare well plates coated with collagen type 0 derived from with plates coated with bovine and porcine collagen.

Republication: and Analysis of Collagen Foams for Soft and Hard Tissue Regeneration.

Background/aim: The aim of this study was the conception, production, material analysis and cytocompatibility analysis of a new collagen foam for medical applications.

Materials And Methods: After the innovative production of various collagen sponges from bovine sources, the foams were analyzed ex vivo in terms of their structure (including pore size) and in vitro in terms of cytocompatibility according to EN ISO 10993-5/-12. In vitro, the collagen foams were compared with the established biomaterials cerabone and Jason membrane.
