Memristive biosensors have demonstrated excellent capabilities for ultrasensitive bio-detection. In the present work, memristive biosensing chips are designed, fabricated and implemented in a for the first time presented multi-panel on-chip detection for discrete sensing of a target molecule through separate functionalization of individual devices on the same chip. The biosensing scheme is validated by means of labeled (i.e. fluorescence) and label-free (i.e. electrical) characterization methods. This novel memristive multi-panel sensing paradigm paves the way for fast and ultrasensitive PoC (point-of-care) devices allowing the detection of specific targets in complex matrixes where non-specific molecules are present as well, and opening great potential for the application of memristive phenomena in multiplexed ultrasensitive bio-detection and theranostics.
