Hot and Spicy!

So how hot is hot? You can measure the heat of a chili pepper with your tongue, but how accurate is that? Everyone's definition of "hot" is different. Scientists are now using a new carbon nanotube-based sensor to quantify the "heat" of chili peppers.

Capsaicin is the chemical responsible to the hot taste of chili peppers and ban be detected using electrochemical methods. The carbon nanotubes are used as tiny electrodes to measure the amount of capsaicin in the sample. This biosensor makes testing how hot a chili pepper is easy, precise, and inexpensive.
