Figure 1. C1s narrow scan XPS spectra of the surface of PLGA films before and after laser irradiation.

Figure 1

Black, red and blue lines indicate before laser irradiation, after laser irradiation with 800 nm at 1.0 J/cm2, and after laser irradiation with 400 nm at 0.15 J/cm2, respectively. The scanning speed was 30 μm/s.
