Terahertz aptasensor for dopamine neurochemical detection

Research output: Contribution to journalLetterpeer-review

Abstract

Measuring neurotransmitter levels in the body can identify imbalances and diagnose neurological and psychiatric disorders. Several advanced imaging technologies and electrochemical and optical sensors have been developed for a highly sensitive and selective detection of neurotransmitters. In this study, a terahertz chemical microscope (TCM) for measurement of dopamine levels is proposed. The TCM uses terahertz waves to obtain a label-free chemical reaction on a sensing plate. A DNA aptamer is investigated as a recognition element for detection of dopamine. The measurement mechanism and construction of the terahertz aptasensor are described, providing a potential alternative for neurotransmitter detection.
