Due to their rare combination of high chemical stability, exceptional optical and electrical properties, high surface-to-volume ratio, and high aspect ratio, carbon nanotubes (CNTs) have made an enormous impact on materials science, molecular biology, biomedicine, and bioanalytical chemistry. Carbon Nanotubes: Methods and Protocols provides reliable, consistent protocols on the application of CNTs in molecular biology-related fields. These are of vital importance, as the commercially available CNTs differ in purity, agglomeration state, as well as length and diameter distribution, all of which have a profound influence on the dispersability and surface properties of the tubes.
