World's smallest thermometer created from DNA

Canada-based biochemists have developed the world's smallest thermometer from DNA, which is 20,000 times smaller than a human hair. The device is based on a property of DNA, which causes it to fold or unfold depending on the temperature changes. The property allowed the team to create programmable molecules which can aid in measuring temperatures between 30°C and 85°C.

World's tiniest thermometer made of DNA is 20,000 TIMES smaller than a human hair

Biochemists designed genetic strands that unfold at specific temperatures 

By combing these they can measure temperatures between 86°F and 185°F

It could provide new ways of monitoring temperatures at a cellular level

They could also provide precise measurements in electronic devices
