The efficient sensing of amino acids, especially the distinction their chiral enantiomers, is important for biological, chemical, and pharmaceutical research. In this work, a THz phase shift method was performed acid detection based on polarization-dependent electromagnetically induced transparency (EIT) metasurface. More importantly, binding specific acids to functional proteins modified metasurface developed isoelectric point theory so that recognition Arginine (Arg) achieved among four...
Metasurface (MS)-based terahertz (THz) biosensors have attracted significant attention in the biological field due to their nondestructive and harmless interaction with biochemical samples. However, it is still challenging for specific detection mixed samples via THz metasensors. In this work, we modified MS chips target biomolecules, respectively, utilized immune binding gold nanorods (GNRs), achieved high-sensitive Alzheimer's marker <inline-formula...
The recognition of chiral enantiomers by a metasurface was realized; both the detection sensitivity and precision were enhanced gold nanoparticles.
A terahertz (THz) all-dielectric metasurface with crescent cylinder arrays for chiral drug sensing has been demonstrated. Through the multipole expansion method, we theoretically found that breaking symmetry of can excite higher-order resonance modes and provide stronger anisotropy as well enhanced sensitivity surroundings, which gives a better performance than lower-order resonance. Based on frequency shift transmittance at resonance, carried out experiments (R)-(−)-ibuprofen...
Protein denaturation has very important research value in nutrition, biomedicine, and the food industry, which is caused by changes molecular structure of protein. Since collective vibrational torsional modes protein molecules are within terahertz (THz) frequency range, THz spectroscopy can characterize with several advantages non-contact, label-free, real-time, non-destructive. Therefore, we proposed a reflective time-domain polarization sensing method, use flexible twisted dual-layer...
Terahertz (THz) communication and sensing technology has recently gained increasing attention. Metallic parallel-plate waveguides (PPWG) have been researched since they were proven to be the carrier of lossless transmission THz waves. However, previous reports focused on phase properties single-polarized waves in PPWGs barely investigated polarization properties. To reconstruct output wave a PPWG, we study both TE TM modes detail. The difference can continuously adjusted by varying...
Abstract Multi-resonant metasurfaces are of great significance in the applications multi-band nanophotonics. Here, we propose a novel metasurface design scheme for simultaneously supporting quasi-bound states continuum (QBIC) and other resonant modes, which QBIC resonance is generated by mirror or rotational symmetry breaking oligomers while modes can be excited rationally designing shapes meta-atoms within oligomers. As an example, simultaneous excitation anapole demonstrated dimer composed...
Terahertz (THz) sensors have attracted significant attention in the biological field due to their non-destructive and harmless interaction with biochemical samples, but how achieve efficiently specific sensing for small molecular weight samples is still challenging. In this work, we incorporated an all-dielectric metasurface functionalized gold nanoparticles (Au NPs) realize immunosensing of target biomolecule at nanomole-level concentration. These Au NPs are modified by Anti-HA tag...
