Using microorganisms to appraise water quality within minutes | Envirotec
Researchers from the Singapore University of Technology and Design (SUTD) say they have demonstrated a technology that rapidly detects pollutants in water by measuring their impacts on swimming microorganisms.
Their proof-of-concept, published in Scientific Reports, does not require any chemicals, reagents or laboratory equipment. Instead, it leverages the regular camera of a smartphone as well as microorganisms called Paramecia that are ubiquitous in water bodies–making it especially suitable for assessing water drinkability in underdeveloped regions.
