⚡ Terahertz Materials are metamaterials that can interact with light at terahertz frequencies, penetrate fabrics and plastics, and use remote surveillance to uncover weapons and drugs that a person may carry.

🛡️ Terahertz metamaterials can fool these security systems by cloaking the target when they surround it. They also can enhance the quality of the terahertz signal source used for surveillance and even be used as a terahertz source themselves.

🍄 Moreover, terahertz metamaterials are also used to detect bacteria, fungi, viruses and single molecules in microfluidic platforms.
