Abstract
A method of detecting the presence of an ion includes contacting a nucleic acid enzyme with a sample suspected of containing the ion, where the enzyme contains a ribonucleotide and is dependent on the ion to produce a product from a substrate, and measuring an amount of the product produced. The ion is Pb2+, and is in the presence of other ions.
