Abstract :
The article reports the use of a metal-cluster-decorated carbon nanotube biosensors for rapid and label-free algae cell detection. Sensitivities of the devices with or without the metal-cluster coating were subsequently compared using streptavidin (SA) as a model case. The sensing responses of device conductance (G) normalized by initial conductance (G0) plotted versus time for devices without and with metal clusters are shown.
