DNA-Based Nanowires can Create, Detect Light

Facebook X LinkedIn Email
PROVIDENCE, R.I., July 21, 2006 -- For the first time, a research team has used the coding power of DNA to create nanowires on top of carbon nanotube tips. The tiny new structures can create and detect light, and, with mechanical pressure, generate electricity. The wires' optical and electrical properties would allow for a range of applications, the researchers said, from medical diagnostics and security sensors to fiber-optic networks and computer circuits. A small but growing number of engineers are using nature's engineer -- DNA -- to create nanomaterials that can be used in everything from medical devices to computer...Read full article

    nanotube
    A nanotube, also known as a nanotubule or simply a tube-like structure, is a nanoscale cylindrical structure composed of various materials, including carbon, boron nitride, or other compounds. Nanotubes have unique physical and chemical properties due to their small size and specific atomic arrangement, making them of significant interest in various scientific and technological fields. One of the most well-known types of nanotubes is the carbon nanotube (CNT), which is composed of carbon...
