New Detectors Developed At MIT Could Provide Easy Visual Identification Of Toxins Or Pathogens.

Researchers at MIT have developed a new way of revealing the presence of specific chemicals - whether toxins, disease markers, pathogens or explosives. The system visually signals the presence of a target chemical by emitting a fluorescent glow. The approach combines fluorescent molecules with an open scaffolding called a metal-organic framework (MOF). This structure provides lots of open space for target molecules to occupy, bringing them into close proximity with fluorescent molecules that react to their presence...
