OR FULLERENES USING MOLECULAR MODELING SOFTWARE WOULD MAKE FOR A COOL SCIENCE
PROJECT. THEY ARE IN THE FOREFRONT NOW IN DRUG DELIVERY AND NANOTECHNOLOGY.
Small Times, Big Times News
17, 2003 - Buckyballs, the soccer ball-shaped molecules that helped kick-start
interest in nanoscale science and technology in the 1990s, finally made the big
time. The biotech startup C Sixty announced Thursday that it is partnering with
the pharmaceutical company Merck & Co. to develop drugs based on buckyballs,
formally known as buckminsterfullerenes. " for full article
web defines nanotechnology as any technology related to features of nanometer
scale: thin films, fine particles, chemical synthesis, advanced microlithography,
and so forth. Nanotechnology is therefore more of a 'catch-all' description of
activities at the level of atoms and molecules that have applications in the real
world. Although nanotechnology stocks are in a frenzy, and the media talks of
nanotechnology as being the "new technology", research in the field has actually
been ongoing for many years. In the last 15 years over a dozen Nobel prizes have
been awarded in nanotechnology, including the development of the scanning probe
microscope (SPM), and the discovery of fullerenes. It was perhaps the discovery
and potential applications of the fullerene molecule (also called a buckyball)
and a related structure, the buckytube (or nanotube), that has sparked the current
interest in the field.
ARE THE APPLICATIONS FOR NANOTUBES AND FULLERENES?
nanotubes (CNTs) have caught the imagination of scientists for everything from
superconductors to transistors and diodes, material strengtheners, ion storage
for batteries and more. One of the most promising applications is a thin panel
called a field emitter display (FED). Both Motorola and DuPont are presently investigating
on the charge, the flexible nanotube can bend upward, away from the electrode,
or downward, into contact with the electrode. The resulting signals form the building
blocks of a digital device. "The best thing is, these switches are working," Norm
Armour from LSI said. "We built some test devices, and we fired them up the other
day, and they worked." The nanotube-based memory can act like "flash" memory,
a reprogrammable type of memory that can retain data even when power is switched
(C60) are being investigated for their potential use as a drug-delivery system
for cancer, AIDS and other diseases.
long term objective of nanotechnology is to build nano-sized machines which can
be inserted into the human body in order to detect and repair diseased cells is
a real possibility. Current research however, is only at the primitive levels
designing simple components e.g., a carbon nanotube based gears.
