Abstract:
An innovative chemical strategy integrated in a miniaturized electrochemical device was developed for sensitive detection of a pathogen genome (HBV virus) without any amplification step. The results show a limit of detection comparable to the standard qRT-PCR method (20 copies per reaction), paving the way to future development of genetic PoC devices addressing automatized and low-cost molecular diagnostics.
