Exploring Neurotransmitter Dynamics Optical investigation of molecular dynamics occurring within the biomimetic human biosensor system, especially under water environment, has been regarded as a challenging area of study. Based on the great advantage of spectral capabilities of terahertz spectroscopic tools, a unique biosensing platform has been proposed assisted by nanodisc-hybridized nanoscale metasurfaces. The sensing capability was determined to enable the receptor-ligand interactions occurring at optical hotspots, where the terahertz field was strongly localized and greatly enhanced, and controlled by targeting specific frequency of the metasurface.
