Royal Society of Chemistry, the U of Alberta researchers have already made the
processor and unit smaller and have brought the cost of building <STRONG>a
portable unit for genetic testing</STRONG> <STRONG>down to about $100
Cdn</STRONG>.</FONT></A> In addition, these systems are also portable and even
faster (they take only minutes). Backhouse, Elliott and McMullin are <STRONG>now
demonstrating prototypes of a USB key-like system </STRONG>that may ultimately
be as inexpensive as standard USB memory keys that are in common use –
<STRONG>only tens of dollars</STRONG>. It could help with Pandemic disease
control and detecting and controlling tainted water supplies.<BR><BR>This
development fits in with my belief that there should be <A

<BLOCKQUOTE>Canadian scientists have <A
href="http://www.rsc.org/Publishing/ChemScience/Volume/2008/02/Genetic_testing_shoe-box.asp"
target=blank><FONT color=#5588aa>succeeded in building the least expensive
portable device for rapid genetic testing ever made</FONT></A>. The cost of
carrying out a single genetic test currently varies from hundreds to thousands
of pounds, and the wait for results can take weeks. Now a group led by <A
href="http://www.ece.ualberta.ca/~chrisb/" target=blank><FONT
color=#5588aa>Christopher Backhouse</FONT></A>, University of Alberta,
Edmonton, have developed a reusable microchip-based system that costs just 500
(pounds) to build, is small enough to be portable, and can be used for
point-of-care medical testing. <BR><BR>To keep costs down, 'instead of using
the very expensive confocal optics systems currently used in these types of
devices we used a consumer-grade digital camera', Backhouse explained.
<BR><BR>The device can be adapted for used in many different genetic tests.
'By making small changes to the system you could test for a person's
predisposition to cancer, carry out pharmacogenetic tests for adverse drug
reactions or even test for pathogens in a water supply,' said
Backhouse.</BLOCKQUOTE></DIV></DIV></FONT>
<DIV dir=ltr><FONT face=Arial color=#000000 size=2>
<BLOCKQUOTE>The heart of the unit, the ‘chip,’ looks like a standard
microscope slide etched with fine silver and gold lines. That microfabricated
chip applies nano-biotechnologies within tiny volumes, sometimes working with
only a few molecules of sample. Because of this highly integrated chip
(containing microfluidics and microscale devices), the remainder of the system
is inexpensive ($1,000) and fast.<BR><BR>There are many possible uses for such
a portable genetic testing unit: <BR><BR>Backhouse notes that adverse drug
reactions are a major problem in health care. By running a quick genetic test
on a cancer patient, for example, doctors might pinpoint the type of cancer
and determine the best drug and correct dosage for the individual. <BR><BR>Or
health-care professionals can easily look for the genetic signature for a
virus or E. coli – also making it useful for testing water quality.
<BR><BR>“From a public health point of view, it would be wonderful during an
epidemic to be able to do a quick test on a patient when they walk into an
emergency room and be able to say, ‘you have SARS, you need to go into that
(isolation) room immediately.’ ” <BR><BR>A family doctor might determine a
person’s genetic predisposition to an illness during an office visit and
advise the patient on preventative lifestyle
changes.</BLOCKQUOTE><BR></FONT></DIV></DIV>
