Description
A study from The University of Sydney details the in vitro characterization of a plasma-activated coating (PAC) applied to Cobalt Chromium alloy L605, a key biomaterial for drug-eluting and bare metal stents. Surface hydrophilicity, chemistry, roughness, and stiffness were measured using water contact angle, energy dispersive x-ray spectroscopy, white light interferometry, and nanoindentation. The research demonstrates improved biocompatibility for the modified PAC-L605 material, which showed robust adhesion and a non-delaminating character under compression.
Use Cases
Compare surface hydrophilicity based on water contact angle and plasma kinetics measurements
Analyze surface chemistry differences based on carbon and nitrogen weight percentages from energy dispersive x-ray spectroscopy
Evaluate microscale surface roughness based on white light interferometry data
Assess material stiffness and coating adhesion based on nanoindentation results from 0.19 mN to 50 mN loads
Strengths
Surface properties were characterized using multiple established techniques, including water contact angle, EDS, WLI, and nanoindentation.
The study provides a direct comparison between the modified PAC-L605 surface and the base L605 alloy.
