In what ways do one-dimensional nanostructures aid in bioelectronic sensing?
Importance of one-dimensional nanostructures like CNTs for bioelectronic
detection stems from their electronic transport properties besides their high
surface-to-volume ratio and the capacity to bunch a tremendous density of
sensing elements on the footprint of a small array device. Carbon nanotubes
work as efcient substrates or modiers for promoting ET reactions. They
exhibit excellent electron transfer supporting ability when used as electrode
modier in electrochemical reaction electrodes. This ...
