Fluorescent RNA sensor gets 10 times more sensitive for water safety

Phys · · 489 words · By Fannie; John Hertz Foundation

Researchers at Northwestern University have developed ROSALIND, a cell-free RNA sensor platform that detects water contaminants. The latest version features a signal amplification circuit that increases sensitivity tenfold and is currently being tested in field trials in Chicago and East Africa.
