The device is the size of a BlackBerry, or an I-Phone and uses nanotechnology
“UofT researchers have used nanomaterials to develop a microchip sensitive enough to quickly determine the type and severity of a patient’s cancer so that the disease can be detected earlier for more effective treatment.
Their groundbreaking work, reported Sept. 27 in Nature Nanotechnology heralds an era when sophisticated molecular diagnostics will become commonplace.
“This remarkable innovation is an indication that the age of nanomedicine is dawning," says Professor David Naylor, president of the University of Toronto and a professor of medicine. “Thanks to the breadth of expertise here at U of T, cross-disciplinary collaborations of this nature make such landmark advances possible."
The researchers' new device can easily sense the signature biomarkers that indicate the presence of cancer at the cellular level, even though these biomolecules – genes that indicate aggressive or benign forms of the disease and differentiate subtypes of the cancer – are generally present only at low levels in biological samples.
Analysis can be completed in 30 minutes, a vast improvement over the existing diagnostic procedures that generally take days.”
