Nanoscale Resonator to detect Dangerous Chemicals

Most insects have tiny hairs on their body but it is not clear what the hairs are for. Scientists are  trying to make sense of what these hairs may be capable of, so they designed experiment involving“forest” of tiny hairs on a thin vibrating crystal chip. They were thinking that this device can work like a smaller and cheaper spectrometer, measuring chemicals in the parts-per-million range.” Using resonators as sensors, because it’s highly undesirable most people want to get rid of dissipation or friction, it tends to obscure what you are trying to measure. Scientists have taken that undesirable thing and made it useful.”

“Without chemical receptors, sensing chemicals has been a challenge in normal conditions, scientists realized that in the frictional loss of a mechanical resonator in motion, there is a wealth of information contained and it is more pronounced at the nanoscale.”Any object moving rapidly through the air can probe the properties of the surrounding environment. We can imagine a wand in your hand and moving it back and forth, and even just by feeling the resistance and with our eyes closed we can feel whether the wand is moving through air, honey or water. When picturing this wand with billions of tiny hairs on it, moving back and forth several million times per second and just imagine the sensing possibilities. With the nanostructures, we can feel that tiny changes in the air surrounding the resonator. “This device will be useful for detecting a wide variety of chemicals by the sensitivity.”

For sensing by living organisms, similar mechanisms involving motions of nano-hairs may be used because the friction is changing dramatically with time changes with the environmental and It is easy to measure, it may be possible to designed to plug into a wall and eventually produce a gadget of the similar size or slightly larger than a Rubik’s cube and Presently to sensing chemical vapours in air, the group’s device is geared primarily. Versatility sets the device apart from larger and more expensive equipment, Apart from size and reasonable cost. “Because our sensor is not directed to detect any specific chemical and it doesn’t require that we actually attach the molecules to anything to create a mechanical response, it can interpret a broad range, meaning that it’s also reusable.
