Winnipeg scientists in Canada are working on a portable, low-cost instrument called a biochip sensor. The device is able to quickly detect if someone is carrying or infecting the H1N1 virus.
Recently, the study won a local creative contest and a $5,000 bonus. According to the researchers, biochip sensors allow non-medical personnel to detect the flu virus within an hour, and only $10 per test. With current technology, such testing can cost hundreds of dollars.
The scientists also said that through certain calibrations, the portable devices they developed could detect certain pathogen antibodies and diagnose some infectious diseases such as SARS, HIV and hepatitis B.
Michael Zhang, the project leader, Winnipeg biomedical engineer and assistant professor at the University of Winnipeg, said, "This instrument can be used in cancer testing, and anyone can use it at home or in their family doctor's office. Detection."
Zhang Gong and his colleagues won the Canadian Biomedical Development Association's annual competition by defeating the other four groups of participants. Zhang Gong’s team members include Simon Liao, a computer professor at Winnipeg University, Bin Huang, an electronics engineer, and Francis Lin, a biophysicist at the University of Manitoba.
Researchers will use the bonus and some of their own funding to complete the modeling of the handheld device. The model will be able to detect a particular disease through a saliva test. Once the model construction work is completed, they will need more funds to conduct clinical tests to prove that the instrument is working properly. Only through clinical testing will the device be approved by professional departments such as the Canadian Department of Health and the US Food and Drug Administration.
Joel Kettner, chief executive of public health in Manitoba, said that such diagnostic equipment has potential benefits as long as it is used properly.
“As a monitoring tool, this device is very useful,†Kettner said. “If the test results are accurate enough, the instrument is a boon to those who are not worried about the disease and who are worried about their illness.â€
But using this instrument to provide medical decisions for a confirmed patient is another matter. He said, "People don't want to worry about things that happen because of misdiagnosis of the instruments."
