The Israelis have developed a chip that detects explosives in the air at a distance of up to five meters
The new chip with microscopic chemical sensors able to smell explosives in air at concentrations of the order of molecules per quadrillion, which is a million times more sensitive than today's sensors. The article about this development was опубликована in the journal Nature Communications.
During tests it has proved effective at a distance of up to five meters in the air, strongly polluted by cigarette smoke. Since we are talking about basic research in everyday life scanners based on this design will be more distant day, пишет Gizmodo.
Directly "nose" of the chip are clusters of nanoscale transistors, which are extremely sensitive to chemically induce changes in their electrical conductivity at surface contact ( phys.org ).
