NapC is a tetra-haem member of a family of bacterial membrane-anchored multi-haem c -type cytochromes implicated in electron transfer between membrane quinols and periplasmic enzymes. The(More)
Binary polymer brush patterns were fabricated via photodeprotection of an aminosilane with a photo-cleavable nitrophenyl protecting group. UV exposure of the silane film through a mask yields(More)
