Divalent Cation Dependence Enhances Dopamine Aptamer Biosensing

Nako Nakatsuka

Oligonucleotide receptors (aptamers), which change conformation upon target recognition, enable electronic biosensing under high ionic-strength conditions when coupled to field-effect transistors (FETs). Because highly negatively charged aptamer backbones ...
