Researchers at Jamia Millia Islamia, New Delhi, have developed an ultrasensitive quantum thermometer using graphene quantum dots. Features
- The quantum thermometer can precisely measure a wide range of temperature: 27 degrees C to –196 degree C. It can also be used for measuring high temperatures up to 100 degrees C.
- It has high sensitivity when measuring different temperatures.
- It can measure micro Kelvin changes in temperature and has a quick response time.
- It can be made to any shape and dimension.
About Graphene quantum dots (GQDs)
- It will be useful in the pharmaceutical industry, healthcare to measure the incubation temperature of biological cells and molecules.
- Automobile industry to measure the ignition temperature within the engine.
- It can also find widespread applications in cryogenic temperature sensing.
