Design and fabrication of a solid-state chemiresistive sensor for the detection of hexavalent chromium
The present work reports the use of a conjugated organic molecule for the detection of hexavalent chromium ions. The organic molecule designed herein is a guanidine-based moiety that has shown a limit of detection as low as 1ppm when used in the form of a chemiresistive sensor.
