Enhancement of fast scan cyclic voltammetry detection of dopamine with tryptophan-modified electrodes. [PDF]

PLoS ONE, 2020
Fast scan cyclic voltammetry (FSCV) allows for real -time analysis of phasic neurotransmitter levels. Tryptophan (TRP) is an aromatic amino acid responsible for facilitating electron transfer kinetics in oxidoreductase enzymes.

Multiplexed DNA-Modified Electrodes [PDF]

Journal of the American Chemical Society, 2010
We report the use of silicon chips with 16 DNA-modified electrodes (DME chips) utilizing DNA-mediated charge transport for multiplexed detection of DNA and DNA-binding protein targets. Four DNA sequences were simultaneously distinguished on a single DME chip with 4-fold redundancy, including one incorporating a single base mismatch.
