Nano nod for lab-on-a-chip

By R&D Editors | April 25, 2012

Domino Technology

The Domino technology uses a plastic chip that can perform 20 genetic tests from a single drop of blood.

You wouldn’t know it from
appearances, but a metal cube the size of a toaster, created at the University
of Alberta (U of A), is capable of performing the same genetic tests as most
fully equipped modern laboratories—and in a fraction of the time.

At its core is a small plastic
chip developed with nanotechnology that holds the key to determining whether a
patient is resistant to cancer drugs or has viruses like malaria. The chip can
also pinpoint infectious diseases in a herd of cattle.

Talk about thinking outside the
box.

Dubbed the Domino, the
technology—developed by a U of A research team—has the potential to
revolutionize point-of-care medicine. The innovation has also earned Aquila
Diagnostic Systems, the Edmonton-based nano startup that licensed the
technology, a shot at $175,000 as a finalist for the TEC NanoVenturePrize
award.

“We’re basically replacing
millions of dollars of equipment that would be in a conventional, consolidated
lab with something that costs pennies to produce and is field portable so you
can take it where needed. That’s where this technology shines,” said Jason
Acker, an associate professor of laboratory medicine and pathology at the U of
A and chief technology officer with Aquila.

The Domino employs polymerase
chain reaction (PCR) technology used to amplify and detect targeted sequences
of DNA, but in a miniaturized form that fits on a plastic chip the size of two
postage stamps. The chip contains 20 gel posts—each the size of a
pinhead—capable of identifying sequences of DNA with a single drop of blood.

Each post performs its own
genetic test, meaning you can not only find out whether you have malaria, but
also determine the type of malaria and whether your DNA makes you resistant to
certain antimalarial drugs. It takes less than an hour to process one chip,
making it possible to screen large populations in a short time.

“That’s the real value
proposition—being able to do multiple tests at the same time,” Acker said,
adding that the Domino has been used in several recently published studies,
showing similar accuracy to centralized laboratories.

The Domino effect:
Personalized medicine

The Domino was developed by a team led by Linda Pilarski, an experimental
oncologist with the Faculty of Medicine & Dentistry and a former Tier 1
Canada Research Chair in biomedical nanotechnology.

In 2008, her team received $5
million over five years from Alberta Innovates Health Solutions to perfect and
commercialize the technology. As an oncologist, Pilarski is interested in its
pharmacogenomic testing capabilities, such as determining whether breast cancer
patients are genetically disposed to resist certain drugs.

“With most cancers you want to
treat the patient with the most effective therapeutic as possible,” she said. “That’s what this does: It really enables personalized medicine. It will be
able to test every patient at the right time, right in their doctor’s office.
That’s currently not feasible because it’s too expensive.”

Along with its versatility, two
key selling points are affordability and portability, with each portable box
expected to cost about $5,000 and each chip a few dollars, says Aquila president David Alton. It’s also designed to be
easy to use and rugged—important features for the livestock industry, the
company’s first target market. The Domino will be put through trials within a
year at one of the country’s largest feedlots in southern Alberta.

Alton credits Aquila’s
relationship with the U of A, not just for the research but for the business
relationship with TEC Edmonton that has helped the company license and patent
Domino. TEC Edmonton is a joint venture between the U of A and Edmonton
Economic Development Corporation with resources and expertise to help startups
in the early stages of operations.

“We see a huge potential market
for the technology and we’re looking at applying the technology developed here
at the U of A to markets first in Alberta
and then globally, to address important health issues here and throughout the
world.”
