Preparation and properties of asymmetric porous antimicrobial nZnO/P34HB composite guided bone regeneration membrane
Published 2024-12-01“…Methods Ultrasonic dispersion technique, solvent displacement method and freeze-drying technique were used to prepare P34HB composite GBR membrane loaded with nZnO at different doses (0%, 0.5%, 1.0% and 1.5%).Scanning electron microscopy (SEM) and energy spectrometry (EDS) were conducted to determine the load of nZnO and observe the structure of the prepared membrane.Then MC3T3-E1 cells were implanted in a 24-well culture plate with the prepared GBR membrane pre-laid in the well.Thus the experiment included blank control group (no membrane) and groups with membranes composing 0%, 0.5%, 1.0% and 1.5% nZnO, respectively.CCK-8 and cell scratch assays were used to detect cell proliferation capacity and migration ability.The protein adsorption capacity of GBR membrane was detected by protein adsorption experiment.The in vitro degradation of GBR membrane was tested; the activity of alkaline phosphatase (ALP) was detected with chemical test.And calcified nodules were observed with alizzarin red staining; the antibacterial ability of GBR membranes was tested with in vitro antibacterial experiments. …”
