Optical density measurements of 24 h biofilm growth on pluronic coated TCPS surface in the presence of different concentrations (0.01 mg/mL, 0.05 mg/mL, 0.10 mg/mL, and 0.15 mg/mL) of iron-oxide nanoparticles. ∗Significant difference at P < 0.05 compared to control (absence of iron-oxide nanoparticles). # denotes significant difference at P < 0.05 compared to control (absence of iron-oxide nanoparticles) and + denotes significant difference at P < 0.05 compared to control (absence of iron-oxide nanoparticles).
