Abstract
  • Electrochemical DNA detection systems are an attractive approach to the development of multiplexed, high-throughput DNA analysis systems for clinical and research applications. We have engineered a new class of nanoelectrode ensembles (NEEs) that constitute a useful platform for biomolecular electrochemical sensing. High-sensitivity DNA detection was achieved at oligonucleotide-functionalized NEEs using a label-free electrocatalytic assay. Attomole levels of DNA were detected using the NEEs, validating the promise of nanoarchitectures for ultrasensitive biosensing.
