Quantitative protein adsorption from DMEM cell culture medium supplemented with 10% FBS on pEHPA-b-BP and pEHPMA-b-BP brush coatings and TCPS controls via QCM-D measurements. (a) Representative frequency curves of the protein adsorption at 37 °C. (b) Areal mass of adsorbed proteins derived from the frequency changes Δf via the Sauerbrey equation, measured at the start and end of the experiment, following protein exposure for 20 min and a 5 min PBS flush. Bars indicate mean values along with standard deviation (n ≥ 3).
