Andrew Hook – <strong>Patterned</strong> <strong>and</strong> <strong>switchable</strong> <strong>surfaces</strong> <strong>for</strong> <strong>biomaterial</strong> <strong>applications</strong>Figure 4.3. (A) Chemical schematic of an amine or carboxylic acid functionalpolymer [M] n functionalised with phenylazide functional groups byincubating with NSANB <strong>and</strong> its activation <strong>for</strong> surface immobilisation <strong>and</strong>inter- <strong>and</strong> intra-molecular crosslinking. For carboxylic functional polymerthe NSANB was initially amine functionalised by a reaction withethylenediamine. (B-E) structures of polymers used; (B) PAA, (C) PEI, (D)PLL, (E) PVP.4-141
