A metamaterial absorber developed by researchers from the Korea Institute of Machinery and Materials (KIMM) under the Ministry of Science and ICT and UNIST is able to significantly enhance the detection of harmful substances or biomolecules. The proposed metamaterial described in the research gathers and releases light energy simultaneously, inducing a greater intensity of light that can be absorbed by molecules. The amplified signals allow more distinct (precise) results, particularly when working with small traces of substances.
The material is able to enhance infrared absorption spectroscopy through hundredfold amplification of detection signals and features cross-shaped nano-antennas, formed in a metal-insulator-metal…READ MORE
