Application examples include:
Electrical
IBM has built transistors that operate at room temperature and are capable of digital switching using single electrons. They have also shown how (CNT) transistors can be grown similar to silicon transistors in bulk. They have made wafers with 10 billion junction correctly aligned using (CNT) .
Unidym Inc. has been developing transparent electrically conductive CNT films which are substantially more mechanical robust than indium tin oxide (ITO) the main material used today. This can be used in computer screens, cell phones, ATMs, etc.
CNT has been developed into solar cells by NJIT. They took CNT and Carbon buckyballs to form snake like structures that when exposed to sunlight would make electrons flow.
CNT has been used to improve the performance of Ultracapacitors. This is accomplished by the ability of tailoring the CNT to have the correct spacing of holes where the electrons are stored. Current technology of Ultracapacitors has a lot of these spacing to large or to small to properly store electrons.
Nantero Inc has developed CNT nanoscale electric motors and Mechanical memory elements.
SENSORS
Nanomix has been patenting many sensors using CNT for detecting carbon dioxide, nitrous oxide, glucose, DNA etc.
Fuel cells
The platinum catalyst may be able to be replaced with Nitrogen-doped CNT used to reduce oxygen in fuel cells. In test Nitrogen-doped CNT can reduce oxygen in alkaline solution more efficiently than platinum.
MEDICAL
CNT unique structure allows for implementation of a variety of task around the body. One of them is to be able to target specific areas and thus reducing the dosage of medicine, but still getting the desired effect.
CNT has demonstrated a possible gene delivery vehicle for use in combination with radio frequency to destroy cancer cells.
Mechanical/Composites
CNT has been used in composites with many Polymers to improve thermal, electrical and mechanical performances at much higher strengths than most other materials
