Colorful rendering shows a lattice of black and grey balls making a honeycomb - shaped molecule, the MOF. Snaking around it is the polymer, represented as a translucent string of teal balls. Brown molecules, representing toxic gas, also float around (IMAGE)

Researchers at MIT have developed a detector that could provide continuous monitoring for the presence of toxic gases, at low cost. The team used a material called a metal-organic framework, or MOF (pictured as the black lattice), which is highly sensitive to tiny traces of gas but whose performance quickly degrades.
