Fingerprint spectrum matching-empowered terahertz metamaterial sensor for the ultrasensitive detection of sorbic acid.

Excessive intake of sorbic acid (SA), a widely used food and beverage preservative that acts as a weakly absorbing small molecule in the terahertz band, poses potential hazards to human health. Here, we develop an asymmetric split-square metamaterial sensor and propose an ultrasensitive quantitative detection method ba...
