Photonics.com published research about a tiny, reusable sensor chip create by a UB team led by Peter Liu, assistant professor of electrical engineering.
The sensor uses surface-enhanced infrared absorption (SEIRA) spectroscopy, with technology that is based on nanostructures that are nearly as small as the biological and chemical molecules they aim to detect. Though these nanostructures improve a sensor’s ability to detect molecules, their tiny dimensions make it hard to guide the molecules to the correct area of the sensor. It’s kind of like building a new racing car that is more streamlined and therefore runs faster, but its door is made too small for the driver to enter the car,” said Liu.
