The invention creates composite microparticles by combining platelet lysate proteins with controlled assembly mechanisms, achieving both biocompatibility inherent in biological materials and the desired surface topography through structured organization of protein components
2Reliability
If conventional protein-based microparticle production methods are used, then biocompatibility is maintained, but production time and cost increase
Solution Approach 1:
The invention extracts and utilizes platelet lysate proteins as the core material, eliminating the need for complex synthetic polymer processing and time-consuming conventional protein microparticle production methods. This extraction approach maintains biocompatibility while significantly reducing production time and cost
Solution Approach 2:
The platelet lysate proteins self-assemble into microparticle structures through controlled oxidative environments, eliminating the need for complex external processing steps.
