Reveo, Inc. announces at NanoTech 2006
that it has teamed with the University of Washington to develop a
breakthrough invention for rapid sequencing of DNA using novel nano-scale
electronic and photonic effects that allow for bypassing many biochemical
steps necessary in conventional DNA sequencing methods. The team will
demonstrate proof of concept. The ultimate goal of this effort is to
produce affordable and easy- to-use commercial products. Access to a rapid,
accurate, simple to use, and portable DNA sequencer has enormous potentials
for impacting a number of areas:
- Allowing for on-site sequencing for field-biology. Such a revolutionary
capability will change the way field-biology is conducted today. The
portable sequencer can aid in cataloguing the biodiversity of the
planet and in preservation efforts.
- Allowing for cost-effective sequencing of a large number of genomes
hence producing sizable libraries. Forming such libraries is the
critical step for developing personalized medicine by establishing the
connection between genotypes and phenotypes. The sequencer can
potentially aid in fundamentally changing the way medicine is practiced
today.
The human genome consists of 23 pairs of chromosomes. Each chromosome
is made of long double helix strands; in total the human genome contains
the codes for approximately 30,000 genes. The codes are in the form of
sequencers of four base molecules called nucleotides (A,T,C,G). These
molecules have important properties of Watson-Crick pairing which allow A
to only hybridize with T to form base-pair A-T, and C to only hybridize
with G to form base-pair C-G. It is these pairing properties that enable
the DNA to have its double helix conformation. The genes, through their
unique sequence of base-pairs contain the blueprint or the architecture of
how humans and, indeed, all species are built and how their life functions
are controlled. Different genes control different functions. The life
functions can be disrupted or disturbed by diseases when the proper
sequence is altered. Known as mutation, these alterations are caused by
many external influences, including the environmental conditions, and may
be passed on to the future generations.
Sequencing the entire genome of an individual (measuring approximately
three billion base pairs) using the state-of-the-art tools predominantly
based on the Sanger method requires months and costs tens of millions of
dollars. Realizing the enormous significance and the potential for
benefiting humanity by lowering the cost from millions of dollars to a few
dollars and reducing the sequencing time from months to hours, substantial
world-wide efforts are underway to find alternative sequencing tools.
"Our invention, which is covered by several issued and pending patents,
has the potential of achieving the result for microbial genome in minutes
and for pennies in a portable device," declared Dr. Sadeg Faris, an
inventor of the novel method, and the founder and CEO of Reveo, Inc. Dr.
Faris added, "I have confidence that this new sequencing tool is
realizable, since it is analogous to a tool I had previously invented and
commercialized, the world's fastest oscilloscope, the Pico-second Signal
Processor (PSP-1000), that continues to hold the speed record to this date.
The analogy between the oscilloscope and the new DNA sequencing tool can
simply be understood by replacing the ultra high resolution in time with
one in space." Armed with this analogy, the inventor differentiates his new
tool from all other sequencing tools, which are based on cumbersome
multiple biochemical steps.
The University of Washington (http://www.washington.edu) brings to the
collaboration a tradition of excellence and world-renown pioneering
contributions in genomic sciences. Professor Babak Parviz, director of the
Nanosystems Laboratory and a faculty member in the Department of Electrical
Engineering at the University of Washington, will lead the effort. His team
studies the interaction of DNA and other biomolecules with nanostructures
and investigates molecular signatures. He expresses his enthusiasm
regarding the recently announced partnership by commenting: "We are very
excited about this opportunity. The substantial financial support provided
to the University by the Gordon and Betty Moore Foundation allows us to
move very aggressively and significantly shorten the time between a
laboratory demonstration and a prototype. We have investigated a number of
methods to acquire electronic signatures from DNA strands, proteins, and
other molecules. We are confident that the unique combination of the
multi-disciplinary expertise in our research teams, and the invaluable
knowledge provided by Reveo Inc. will transition ideas to the market."
This breakthrough invention is presented at NanoTech 2006, which is
focusing on nanotechnology and novel applications. Since the key enabling
technology of the sequencer involves making nano probe arrays, Reveo's
announcement of this project is intended to attract other strategic
partners.
