In this study, a light-activated cap was developed, envisaging a biomedical application. The cap was composed of an optical source that illuminates an optical waveguide coated with graphene oxide (GO). Interaction of the light with GO boosts its properties through photothermal and photodynamic effects. A laser diode and polymethyl methacrylate (PMMA) filaments were explored as optical source and optical waveguide, respectively. The deposition of GO on the surface of the filaments was performed by dip-coating method. The optical and thermal properties of the cap, composed of the laser coupled to the PMMA optical waveguide, were evaluated using an IR viewer and a thermal camera. Herein, the obtained experimental results are reported. [ABSTRACT FROM AUTHOR]
