Programming synthetic DNA molecules for building and breaking heterostructures between TiO2 nanomaterials for photoelectrochemical bacterial detection

There is a need for rapid and field-based bacterial detection and identification platforms that do not rely on lengthy growth cultures and lab-based techniques such as mass spectroscopy and polymerase chain reaction. Electrochemical techniques have been developed for culture-free bacterial detection; however, biosensors that deliver a low enough limit-of-detection for direct water pathogen sensing remain elusive. Herein, we report a …
