The Lazarus Vendetta
  • A special research center has been set up
  • Several of the groups are working on
    nanotechnology
  • One group was working on a nannite that would
    look for a specific enzyme to trigger it
  • Then it would go to the cancerous cell and remove
    it from the body
  • The rest would pass harmlessly out through normal
    means
  • A protest group masses outside when it is
    announced that the President of the USA is coming
    for a visit

4
The Lazarus Vendetta
  • The facility is infiltrated two days before the
    Presidents arrival
  • Canisters with bombs attached are planted
  • The bombs go off and millions of nannites are
    released
  • The protesters inhale the nannites
  • Instead of healing them, the protesters are
    slowly dissolved from the inside out

Nanomanufacturing
  • Scientists must be able to manipulate individual
    atoms. This means that they will have to develop
    a technique to grab single atoms and move them to
    desired positions. In 1990, IBM researchers
    showed that it is possible to manipulate single
    atoms. They positioned 35 xenon atoms on the
    surface of a nickel crystal, using an atomic
    force microscopy instrument.

19
Nanomanufacturing
  • The next step will be to develop nanoscopic
    machines, called assemblers, that can be
    programmed to manipulate atoms and molecules at
    will. Trillions of assemblers will be needed to
    develop products in a viable time frame.
  • In order to create enough assemblers to build
    consumer goods, some nanomachines, called
    replicators, will be programmed to build more
    assemblers.

20
Computer Industry
  • Moores Law reaching its physical limit
  • Molecular computers could contain storage devices
    capable of storing trillions of bytes of
    information in a structure the size of a sugar
    cube.
  • Meyya Meyyapan, manager of devices at NASA Ames
    Research Center in San Jose recently suggested
    that, "...the real applications of
    nanoelectronics are 15 years out." (July 2000 -
    Futurist.com)

Nanotechnology is Offering Exciting New
Possibilities for Treating Breast Tumors
  • Dec. 12, 2005, Nanotechwire Nanotechnology,
    using particles as small as 100 nanometers in
    size, is offering exciting new possibilities for
    finding and treating breast tumors, according to
    speakers at the 28th Annual San Antonio Breast
    Cancer Symposium being held this week. Two
    researchers from Rice University in Houston,
    Texas, offered enticing insights into how these
    minute particles can be manipulated to have
    different properties, and tagged with antibodies
    to target them specifically at cancer cells

27
Nano-sponges for Toxic Metals
  • Nov. 14, 2005, Physorg Microscopic particles
    honeycombed with holes only nanometers wide soon
    could help purify industrial runoff, coal plant
    smoke, crude oil and drinking water of toxic
    metals. The particles, made of glass or natural
    diatomaceous earth, are 5 millionths to 50
    millionths of a meter wide and filled with holes
    a thousand times smaller. The surfaces of these
    particles can bear a variety of flavors or
    coatings that soak up specific toxic metals --
    for instance, sulfurous organic coatings attract
    mercury, while coppery organic coatings bind to
    arsenic and radioactive metals known as
    actinides. The particles' spongy nature gives
    them an incredible 6,400 square feet to nearly
    11,000 square feet of surface area per gram of
    material with which to draw in toxins

Virginia Team Using Nano for Brain Cancer
Imaging, Treatment
  • Nov. 14, 2005, Small Times/Richmond Times -
    Dispatch Virginia researchers are loading tiny,
    hollow carbon balls with metals and medicine they
    say could improve the ability to detect and
    destroy brain-cancer cells. Brain cancers are
    rare but often deadly. Cancerous cells often
    stray from the main tumor, making them difficult
    to find. They're troublesome to treat, in part
    because many medicines can't get from the
    bloodstream into the brain, and tricky to remove

29
Quantum Dots Show White Light Promise
  • Oct. 28, 2005, Small Times/United Press
    International Vanderbilt University scientists
    in Nashville, Tenn., say quantum dots could
    become the successor to the light bulb. Until now
    quantum dots have been known primarily for their
    ability to produce a dozen different distinct
    colors of light simply by varying the size of the
    individual nanocrystals a capability
    particularly suited to fluorescent labeling in
    biomedical applications. But Vanderbilt chemists
    have discovered a way to make quantum dots
    spontaneously produce broad-spectrum white light.

Nanotubes Inspire New Technique For Healing
Broken Bones
  • Jul. 8, 2005, Science Daily Scientists have
    shown for the first time that carbon nanotubes
    make an ideal scaffold for the growth of bone
    tissue. The new technique could change the way
    doctors treat broken bones, allowing them to
    simply inject a solution of nanotubes into a
    fracture to promote healing

31
Quantum Dots Detect Viral Infections
  • Jun. 10, 2005, PhysOrg In what may be one of
    the first medical uses of nanotechnology, a
    chemist and a doctor who specializes in
    infectious childhood diseases have joined forces
    to create an early detection method for a
    respiratory virus that is the most common cause
    of hospitalization among children under five.
  • Respiratory syncytial virus (RSV) sends about
    120,000 children to the hospital in the United
    States each year. Although it is only
    life-threatening in one case out of every 100, it
    infects virtually all children by the time they
    are five. Few children in the U.S. die from RSV,
    but it also attacks the elderly, causing some
    17,000 to 18,000 deaths annually. Individuals
    with impaired immune systems are another highly
    susceptible group.
  • Vanderbilt researchers report that not only can a
    quantum dot system detect the presence of RSV
    particles in a matter of hours, rather than the
    two to five days required by current tests, but
    it is also more sensitive, allowing it to detect
    the virus earlier in the course of an infection

32
Nanoparticle Breast Cancer Drug Approved by FDA
  • Mar. 10, 2005, Science Blog Research at
    Northwestern University Feinberg School of
    Medicine played a significant role in Food and
    Drug Administration approval of Abraxane
    (paclitaxel protein-bound particles for
    injectable suspension), indicated for the
    treatment of metastatic breast cancer.
  • "The approval means that women with metastatic
    breast cancer no longer need to endure the
    toxicities associated with solvents and will no
    longer need steroid premedication when they
    receive this albumin-bound form of paclitaxel,"
    said principal clinical study investigator
    William J. Gradishar, M.D., associate professor
    of medicine at Feinberg and co-director, Lynn
    Sage Breast Cancer Program at Northwestern
    Memorial Hospital. Abraxane is engineered using a
    proprietary process (protein-bound nanoparticle
    technology) to create tiny particles
    (nanoparticles 100th the size of a red blood
    cell) in which the active chemotherapeutic drug,
    paclitaxel, is bound to a naturally occurring
    protein called albumin
