Claim:
1. A microfluidic chip comprising a polymeric substrate that has been modified to have a first etched-glass-like surface having a roughness of >3 nm and a second substrate that is bonded to the first etched-glass like surface, wherein at least one of the first or second substrates has at least one channel, groove, recess or hole that forms a conduit at an interface between said substrates; wherein said modified surface consists essentially of a single surface layer of a SiO wherein said modified surface consists essentially of a surface layer of a sulfonated teterafluoroethylene based fluoropolymer-copolymer (“nafion”) or poly[1-(trimethylsilyl)-1-[propyne] (“PTMSP”).
