Microwave-assisted synthesis of bioabsorbable nanoparticles to be used as reinforcement of plga in biomedical applications

Biocomposite materials can be designed to obtain a wide range of mechanical and biological properties. The present work seeks to show the effect of bioabsorbable nanoparticles such as hydroxyapatite and amorphous magnesium phosphates on the mechanical properties of a bioabsorbable polymer in order to develop a biocomposite material 100% bioabsorbable but with mechanical properties superior to those available in the market, which can be used in the manufacture of different biomedical devices. For this work, hydrothermal synthesis assisted by microwave was used to obtain different bioabsorbable nanoparticles which were incorporated into the polymer Poly (L-lactide-co-glycolide) 85:15 (RESOMER LG 857 S, Evonik). The mechanical properties of the biocomposite material were studied using the technique of indentation by AFM and the calculation of the microhardness finding a significant increase of these properties.
