Characterization of the thermostability using IRRAS for the modified surfaces on (a) bare benzoyl-PPX, (b) bare maleimide-PPX, (c) CHX-immobilized surface, (d) BMP-2-immobilized surface, and (e) RGDACC-immobilized surface. The spectra were recorded on the same samples for the selected surfaces with elevated temperatures from 25 °C to 200 °C.
