Title:
RAPID COLORIMETRIC DETECTION OF BACTERIA IN WATER
Document Type and Number:
WIPO Patent Application WO/2015/038555
Kind Code:
A3
Abstract:
The invention provides a nanoparticle (NP)-based detection system for bacteria that is both rapid and sensitive for bacterial analytes in water. The system reports its results colorimetrically, in the form of an easily observable color change, allowing analysis to be done visually by non-scientifically trained personnel.
