Glucose meters aren't just for diabetics anymore. Thanks to a team of chemists, they can be partnered with functional DNA sensors as simple, portable, inexpensive meters for a number of target molecules in blood, serum, water or food. The researchers demonstrated using functional DNA with glucose meters to detect cocaine, the disease marker interferon, adenosine and uranium. The two-step method could be used to detect any kind of molecule that a functional DNA or RNA can bind.
