Scientists from the Laboratory of Two-Dimensional Materials for Microelectronics at the Ioffe Institute, in collaboration with a Russian company, have developed a rapid analyzer known as the "electronic nose." The device can automatically recognize odors and will find applications in medicine, the oil and gas industry, the food industry, and environmental projects. It is aimed at recognizing strong and "harsh" smells. Odor analysis has long been used in medicine and the food industry, as certain smells can indicate signs of illness or food spoilage. This technology has become particularly relevant following the COVID-19 pandemic, as many recovering individuals experienced a diminished sense of smell. Odors are carried by gases, and in industry, gas analyzers—high-precision devices that measure gas concentrations in the air—are traditionally used to detect them. However, smell is not just an objective characteristic of a gas but also a reaction of human olfactory receptors to it, which complicates the task. The "electronic nose" developed by Russian scientists works on the same principle as natural human smell recognition mechanisms. The graphene modifications used in the device, thanks to their physical and chemical properties, form the necessary response to gas molecules. Artificial intelligence analyzes this response, comparing it to its database. “If we draw an analogy with the human nose, the graphene coating acts as receptors, and the signal is transmitted to a control board where the sensitive element is located. This board processes the signal and sends it to a computer or specialized microchips, which compare it to the odor database,” explain the developers. They acknowledge that their device is currently aimed primarily at recognizing strong and "harsh" odors within acceptable concentration limits. The main task of the "electronic nose" is to detect unpleasant odors such as oxides, sulfur-containing compounds, mercaptans (thiols), carbon monoxide, propane, and butane. The device is also targeted at volatile alcohol compounds, ammonia, formaldehyde, and acetone—all crucial for industrial safety.
