Moscow, 28 Dec – AIF-Moscow.
The staff of the physical faculty of Lomonosov Moscow state University has developed the basis for highly sensitive gas sensors that can determine the content of molecules of toxic and nontoxic gases in air at room temperature, said representatives of the University.
The development of new highly sensitive sensors that can accurately detect molecules in the gas phase that are relevant to the modern world, faced with high levels of environmental pollution. The majority of modern gas sensors only works at high temperatures.
Russian scientists have proposed to use for such sensors, porous arrays of nanoscale filaments of silicon. Get them using the method of metal-induced chemical etching. The advantages of this method is that it is inexpensive and is quite fast: in an hour you can get at least a hundred elements.
The study authors noted that the sensors operate at room temperatures and can be used many times. They are promising as to control the extent of environmental pollution and for monitoring the composition of air in enclosed spaces.
