Sensor Tracks Insulin Level

Facebook X LinkedIn Email
NASHVILLE, Tenn., April 16, 2008 -- A sensor built from multiwalled carbon nanotubes can rapidly and continuously measure tiny amounts of insulin in a microfluidic device. Used in conjunction with a new procedure for treating Type 1 diabetes through liver cell transplant, the device could help insulin-dependent diabetics go years between shots. The new insulin detection method also represents a major step toward developing the ability to assess the health of the body's insulin-producing cells in real time, its creators said. Close-up of the new sensor built at Vanderbilt University using carbon nanotubes. The sensor can...Read full article

    Glossary
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    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...
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
    sensor
    1. A generic term for detector. 2. A complete optical/mechanical/electronic system that contains some form of radiation detector.
