A team led by Wen Liaoyong at Westlake University has shrunk a refrigerator-sized cancer detection system into a handheld device, per a study in Nature Photonics. The nanophotonic biosensing device uses a single blood drop and is 10,000 times more accurate than traditional methods.
A single drop of blood may soon help detect early-stage cancer, according to Wen Liaoyong of Westlake University in Hangzhou. Wen and his team have transformed a cancer detection system that once required equipment the size of a refrigerator into something that fits in your hand while improving its accuracy nearly 10,000 times more than traditional methods.
“This work establishes a scalable and robust nanophotonic biosensing paradigm for miniaturised, high-performance diagnostics in clinical, remote and at-home settings,” Wen wrote in the introduction of the paper, which was published in the journal Nature Photonics on May 13.
Special 3D chip
To achieve this result, scientists have changed the method to measure the signal. Instead of measuring light's wavelength, scientists have used a special 3D chip to measure the intensity of light. It allows the device to detect very small changes in the blood sample.
In response, Wen Liaoyong stated that if the measurement range is connected to a 1-meter ruler, it can detect all small changes. In addition, the research team is also looking to find a way to drastically reduce the cost of manufacturing the chip.
Previously a researcher at the University of Connecticut, Wen joined Westlake University’s School of Engineering in 2019 as an assistant professor and independent principal investigator, before being promoted to associate professor last July. His research mainly explores innovative multi-component nanostructured materials and their wide-ranging multifunctional applications.
