Synergistic bio-recognition/spatial-confinement for effective capture and sensitive photoelectrochemical detection of MCF-7 cells

In this communication, a synergistic strategy of bio-recognition/spatial-confinement has been proposed for the effective capture of cancer cells and sensitive photoelectrochemical detection with the lowest limit of detection of 2 cells per mL. The synergistic strategy opens up a new avenue for rational combination of bio-molecule recognition units and nanostructures for bio-detection.
