摘要: Abstract Polydopamine can be formed and deposited on the surface of titanium substrates either by classical dip coating (d-pdopa) or electropolymerization (e-pdopa), which has been recently developed. In contrast to approach, dopamine leads formation continuous, smooth films substrate. We further studied applicability polydopamine examining their ability spontaneously reduce silver ions into metal nanoparticles. A simple bacterial inhibition test was conducted with Escherichia coli Staphylococcus aureus bacteria examine differences in antibacterial efficiency both e-pdopa d-pdopa coated The samples contained clearer zones than samples, is indicative nanoparticles being immobilized film a more efficient manner for antimicrobial functionalization implants.
