Functionalized collagen-silver nanocomposites for evaluation of the biocompatibility and vascular differentiation capacity of mesenchymal stem cells

In this report, a novel nanocomposite based on type I collagen (Col) was prepared, which contained varying amounts (15.1, 30.2, and 75.5 ppm) of silver nanoparticles (AgNPs). The surface morphology and chemical composition pure Col and Col-AgNP nanocomposites (Col-Ag) was characterized by UV–Vis spectroscopy (UV–Vis), atomic force microscope (AFM) and Fourier transform IR spectrometer (FTIR). The biocompatibility effect and biological activity...
