Assessment of biocompatibility and surface topography of poly(ester urethane)–silica nanocomposites reveals multifunctional properties

A poly(ester-urethane) nanocomposite based on 1,6-hexamethylene diisocyanate-trimer, poly(3-hydroxybutyrate), and silica nanoparticles was prepared. The porosity model involved the sodium-acetate in situ particulate leaching technique. Also, the diversity of applications (multifunctionality) of these composite scaffolds is currently unknown. Herein, the scaffold surface topography, cell adhesion, viability, and the use of Azospirillum brasilense...
