A phencyclone derivative is used to achieve light-controlled immobilization of peptides possessing only natural amino acids. The photoactive precursor (blue in picture) is formed in a Diels–Alder reaction and can undergo light-triggered ring-opening reactions with amines. Successful surface patterning with a genuine c(RGDfK) peptide (green) is evidenced by imaging time-of-flight secondary-ion mass spectrometry (ToF-SIMS).
