Reusable Sensor Deploys Nanopatch Antenna for Diagnosis

A tiny, reusable sensing chip developed by University of Buffalo researchers could lead to new point-of-care medical tests. 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. The sensor device’s structure and function. The system features a nano antenna that absorbs infrared to enable analysis of biological and chemical samples.
