Representative XP survey spectrum of MOI-modified silk with neat PFDT under 365Â nm UV illumination for 60Â min (a), representative XP survey spectrum of MOI-modified silk with neat PTOH under 365Â nm UV illumination for 60Â min (b), representative XP survey spectrum of original silk with neat PFDT under 365Â nm UV illumination for 60Â min (c), and representative XP survey spectrum of MOI-modified silk with neat PFDT without UV illumination (d). Binding energy assignments are as follows: O KLL: 990Â eV; F1s: 686Â eV; O1s: 532Â eV; N1s: 400Â eV; C1s: 285Â eV
