Abstract:
Deposition of O-succinimidyl 4-(p-azido-phenyl)butanoate (4) onto inorganic device (FTIR-ATR crystal) or polymer material (filtration membrane) followed by irradiation at 254nm led to surface functionalisation with NHS esters. Further reaction with biomolecules allowed their covalent grafting. The reactivity of the photoactivated surfaces was assayed by two methods: (i) the coupling with 3,5-bis(trifluoromethyl)benzylamine (7) and subsequent XPS analysis; (ii) the coupling with 4,5-bis-tritiated lysine (10) and subsequent LSC measurement of the radioactivity.
