Aptamer-Based Quartz Crystal Microbalance Biosensor for Histamine
Summary
A QCM biosensor for histamine, a marker of fish spoilage and allergic reactions, in which a thiol-modified aptamer is anchored to the gold electrode. After optimising pH, aptamer concentration and immobilisation time, it responded linearly from 0.01 to 1 mg/L with a 0.0071 mg/L detection limit, and recovered 99–109% of histamine spiked into fish sauce.
Summary written by the openQCM team. The original abstract is on the publisher’s page.
