Abstract

Poly(methyl methacrylate) thin films were prepared through solvent casting method followed by thermal treatment to completely remove the residual solvent. All three different tactic PMMAs were studied; the PMMA solution was made in chloroform at various concentrations, with 0.1wt% QDs added against the polymer mass in the polymer solution. PMMA-QDs thin films as well as the pristine PMMA thin film (as control sample) were characterized using a variety of analytical techniques to probe their structure, functionalities, and respective physicochemical properties including thickness, surface wettability, fluorescence emission, and biocompatibility using HeLa mammalian cell as a model cell line. The fluorescence emission steadily increased when the concentration of PMMA increases. The wettability test showed i-PMMA to be more hydrophilic with a smaller contact angle than the other tacticity, while a-PMMA showed to be more hydrophobic with a larger contact angle than the other tacticity. All PMMA-QDs thin films used in co-culturing with HeLa cells supported their growth and proliferation.
