Biosensors are next biggest thing in disease detection

Shared by:

 
In the 20th century, coal miners kept canaries in cages with them when they worked in the mines. These canaries die if the amount of toxic gases such as methane exceeds the normal level, thereby serving as a warning signal to the coal miners so they have sufficient time to escape. The unfortunate canaries served as a primitive form of the biosensors nowadays. Thankfully, medical biosensors have come a long way since then.
