Fast catalytic and electrocatalytic oxidation of sodium borohydride on palladium nanoparticles and its application to ultrasensitive DNA detection.
We report an ultrasensitive DNA sensor using the rapid enhancement of electrocatalytic activity of DNA-conjugated Pd nanoparticles (NPs); the rapid enhancement results from the fast catalytic hydrolysis of NaBH(4) on Pd NPs and subsequent fast hydrogen sorption into Pd NPs.
