Heterogeneous Electrochemical Aptamer-Based Sensor Surfaces for Controlled Sensor Response.


Structure-switching sensors utilize recognition elements that undergo a conformation change upon target binding that is converted into a quantitative signal. Electrochemical, aptamer-based sensors achieve detection of analytes through a conformation change in an electrode-bound, oligonucleotide aptamer by measuring changes in electron transfer efficiencies… (More)
