Carbon nanotubes have a variety of potential applications due to their extraordinary physical properties. They can be used as scanning probe microscope tips for high resolution imaging, magnetic sensors with high sensitivity and spatial resolution, transistors for high frequency circuits, and resonators for force, gas, and biosensing. Carbon nanotubes show promise in drug delivery for cancer therapy, blood testing through microfluidic chips, and tissue engineering as scaffolding. Overall, carbon nanotubes have many potential applications, especially in medicine, due to their strength, thermal conductivity, electrical properties, and ability to be functionalized for targeted delivery.
