Carbon nanotubes-based electrochemical biosensors

For rapid screening nano size biomolecules, a device must be designed in nano sizes, compact and ultra-high sensitive. The most interesting function of the devices is to transduce the binding of biomolecules and devices into electrical signals for further analysis. Over the past few years, nanostructures have emerged as an excellent material to be applied in electrical biosensor. It is because nanostructure-based biosensors have improved much better in rapid detection, sensitivity and selectivity for biosensing compared to conventional biosensing technologies. Here, we highlight the latest developments of carbon nanotubes-biosensors for medical application and their performance for the detection of biomolecules.
