DNA nanoreactor-programmed interface modulation of Schottky junctions via etching for ultrasensitive dual-modal biosensing.
The sensitivity and accuracy of photoelectrochemical (PEC) biosensors are often constrained by high electron-hole recombination rates and reliance on a single detection mode. To address this limitation, an ultrasensitive PEC-colorimetric (CM) dual-mode biosensor has been designed based on DNA nanoreactor-programmed mod...
