Abstract:
In this contribution, we demonstrate a simple carbon nanotube device to electrically detect the presence of bacteria (Escherichai coli) with high sensitivity (<100 cfu/mL) and the glucose triggered metabolic activities of bacteria in real-time. As proof-of-concept demonstration, we also show that this nanoelectronic approach can be employed for high-throughput screening of anti-bacterial drugs.
