Before functionalization, poly (methyl methacrylate) (PMMA) slides of dimensions 25mm x 29mm, were hand-washed with soap and DI water, carefully sprayed with 100% ethanol, and blow dried with nitrogen gas to remove any streaks or impurities. Then the PMMA slides were CO2plasma treated for 15mins for the deposition of activated carboxyl groups using a PlasmaEtch PE-100. After functionalization, contact angle measurements using the Kruss Drop Shape Analyzer DSA30S were performed to assess the hydrophilicity of the functionalized PMMA.
