An electrochemical aptasensor for detection of prostate-specific antigen using reduced graphene gold nanocomposite and Cu/carbon quantum dots
Abstract
An electrochemical aptasensor for the detection of prostate-specific antigen (PSA) is reported, based on a reduced graphene oxide-gold nanocomposite combined with Cu/carbon quantum dots to enhance the electroactive surface and signal transduction. The QCM measurements were performed on a Novaetech (Italy) instrument with AT-cut quartz crystals.
