Scientists at Far Eastern Federal University (FEFU) with colleagues from Russia, Japan, and Australia have developed a multi-purpose sensor based on a specially designed gold film, the surface of which contains millions of parabolic nanoantennas produced by femtosecond laser printing. The sensor identifies molecules at trace concentrations, detecting them in liquid and gas environments. It can be easily adjusted to provide different modalities, including biological studies, medical and security tasks. The related research is published in Nanomaterials.
