Electrochemical sensors for food safety, optical sensors for the detection of heavy metals, and field-effect devices for the detection of viruses are just a few of the many applications for nanotube-based sensors that have been developed.
Among the more recent sensors, CNTs are exceptional because of their inherent lightweight and compact size, extreme strength, great conductivity for both heat and electrical energy, and high specific surface area ratio of surface to mass.
CNTs are cylindrical tubes made from layers of rolled-up graphite.Particularly in terms of their mechanical and electrical properties, nanotubes are highly innovative. In addition to having an astounding tensile strength, they are excellent heat and electricity conductors.
The potential uses for these characteristics in electronics, structural materials, and medicine are exciting. They are actually tiny “tubes” made from graphene “sheets,” which are so small that the name nano is entirely correct.
According to nanoScience Instruments, a carbon nanotube is a substance that is tube-shaped and formed of carbon with a diameter that is measured in nanometers.
The Global nanotube based sensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Engineers at MIT have created a unique sensor that can detect SARS-CoV-2 without the use of antibodies and provides a response in a matter of minutes using specialised carbon nanotubes.
Their novel sensor is built on a platform that can swiftly produce reliable tests, not just for Covid-19 but for upcoming pandemics as well. The diagnostic is based on previously created carbon nanotube sensor technology from Strano’s lab.
After starting to develop a Covid-19 sensor, the researchers needed just 10 days to find a modified carbon nanotube that could detect the viral proteins they were after, test it, and put it into a functioning prototype.
Their strategy, called Corona Phase Molecular Recognition CoPhMoRe, makes use of an effect that happens when particular kinds of polymers bind to a nanoparticle.
These molecules, known as amphiphilic polymers, have hydrophobic areas that act as anchors and hydrophilic regions that create a network of loops extending from the tubes.
