Characterization of PLGA-GO scaffolds. A) Pictures of 3D printed PLGA-GO scaffolds having different concentrations of GO. B) AFM representative images of PLGA and PLGA-GO 2% scaffolds. C) Surface roughness of 3D printed scaffolds. D-E) FTIR spectra of PLGA and PLGA-GO scaffolds. F) Characterization of the 808 nm laser. G) NIR radiation specifications for the 3D printed materials. H-I) Temperature increase in a timespan of 3 min (t3) and 9 min (NF) for PLGA-GO scaffolds. J-K) Production of ROS induced by irradiating scaffolds without cells for 3 or 9 min **p > 0.01 and ***p > 0.001 ANOVA and Turkey post-hoc test.
