Gold-modified paper as microfluidic substrates with reduced biofouling in potentiometric ion sensing
Abstract
Paper gold modifications slow down the protein transport across the substrates. Diminished biofouling of the sensors surface was observed. Gold nanoparticles were the most effective in slowing down the protein transport. Substrates were validated in measurements done in clinically relevant samples.
