Inhibition of Bacterial Adhesion using Calcium Phosphate Microspheres Loaded with Protamine : Figure 3

Figure 3: Morphological observation of protamine loaded-calcium phosphate microspheres. The various concentrations of protamine loaded-CPMs powders were observed by SEM. The concentration of protamine was (a) 0, (b) 125, (c) 250, (d) 500, (e) 1000, and (f) 2000 mg•dm^-3, respectively. Bar represents 500 nm.
