MIT Engineers Create Game-Changing Lead Detection Device

SciTechDaily by David L. Chandler, Massachusetts Institute of Technology

A new chip-scale device could provide sensitive detection of lead levels in drinking water, whose toxicity affects 240 million people worldwide.

Engineers at MIT and collaborators have developed a compact, inexpensive technology to detect and measure lead in water. This new system uses a photonic chip and crown ethers to capture lead ions, providing accurate, near-instant results with just a droplet of water.

Engineers at MIT, Nanyang Technological University, and several companies have developed a compact and inexpensive technology for detecting and measuring lead concentrations in water, potentially enabling a significant advance in tackling this persistent global health issue.
