“…It was shown by Miyamaru et al 8 and Yoshida et al 9,10 that the transmittance property of an MMD changes with substance adsorption. They investigated the optical property change in view of dielectric property change.…”

Biosensing of protein adsorption with metal mesh device (MMD) was investigated by computational calculations and experiments. Electromagnetic field computation was carried out with a single unit cell of MMD. Equivalent circuit model of MMD on the single unit cell was assumed, and the biosensing with MMD was analyzed in detail by computational calculation and experimental measurements. The dip frequency of MMD was shifted by adsorption of protein on MMD. The shift of dip frequency of MMD was proportional to the amount of protein adsorption. The sensitivity of MMD biosensing was dependent on the microstructure of MMD, and proportional to the square of the dip frequency. The refinement of MMD structure can improve the sensitivity of protein detection.

“…Based on this phenomenon, MMD sensors, which detect the quantity of substance from the shift in the spectrum, have been developed. [4][5][6][7][8][9][10][11][12] Metal species for manufacturing are not limited, because MMDs made from various metals have extraordinary transmittance. MMDs offer high-throughput, compared with QCM and SPR, and can be used in screening and initial diagnosis.…”

A biosensor for protein detection was developed using antibody-immobilized metal mesh devices. Antihemoglobin antibodies were covalently immobilized on a metal mesh device. Extraordinary transmission with a dipped structure was observed for a metal mesh device immobilized with antihemoglobin antibodies as well as for the original metal mesh device. Hemoglobin in the mixture solution containing albumin at a hundred-fold concentration was detectable using antihemoglobin-immobilized MMDs. The detectability using the antihemoglobin-immobilized metal mesh device was similar to that of a commercially-available kit for the qualitative determination of hemoglobin.

“…At terahertz (THz) frequencies, refractive index sensing is less well developed. Many of the sensors such as dielectric-coated fibers, metallic meshes, and split-ring resonators have been implemented to sense thin dielectric layers, but the independent variable is the layer thickness rather than the index [5][6][7][8]. In contrast, other sensors in the THz range exist that are not sensitive to the layer thickness [9][10][11].…”
