Fast and Low-cost Tests
The proposal is entitled “SERS substrates for virus detection in exhaled droplets” and was submitted to the category “Cheap rapid tests”. It is based on an optical detection technique of molecules (such as virus proteins) using a laser, called SERS (Surface Enhanced Raman Scattering), which can be easily implemented, even with handheld devices and has a wide range of applications, e.g. drug detection in airports.
The basic idea is to adapt this technique for the detection of the coronavirus by collecting exhaled droplets in air filters, properly modified with nanoparticles. SERS is extremely sensitive and provides results in a few minutes. The utilization of this method will be especially useful in hospitals, schools, airports and other public meeting places.
