VTT develops disposable optical test substrate for detecting harmful microbes

Mon, Nov 20, 2017 08:00 CET

PhD thesis 24.11.2017Harmful microbes and toxic micromolecules in food and drinking water can cause serious health problems around the world. For her PhD thesis, VTT researcher Sanna Uusitalo has developed a disposable optical test substrate for use in microbial detection. The aim is to enable cost-effective detection of harmful microbes and toxins.Uusitalo developed the optical detection of microbial cells using Raman spectroscopy to increase measurement sensitivity via SERS (surface-enhanced Raman scattering) amplification. SERS measurement is based on Raman scattering, whose intensity
