Photonic and Plasmonic Metasensors

Abstract

Biosensors have been designed and developed for detecting biomarkers, biomolecules, proteins, enzymes, organisms, and various types of bacterial and viral diseases since the turn of the century. Initially marred by poor sensitivity, specificity, and selectivity, the advent of the notion of photonic biosensors has successfully addressed such drawbacks. One of the hallmarks of modern pharmaceutical industries is the miniaturization of photonic platforms via continuous scaling down of their sizes, which was accomplished by leveraging the concept of artificial media. Numerous forms of photonic and plasmonic devices have been configured for next-generation technologies since the emergence of metamaterials. Among diverse applications, the development of cost-effective, label-free, selective, precise, and on-chip immunobiosensors with rapid sample-to-result feature has received copious interest, recently. This focused Review brings clarity to the rapidly growing body of available and in-development metamaterials-enabled diagnostic instruments based on inventive and promising approaches. Through centering on the operating principles of plasmonic, photonic, and hybrid metasensors, we mechanistically characterize and describe the properties of such tools and summarize the most recent achievements in devising metasensors and bioimaging tools with high precision. This insightful understanding serves as a comprehensive source for scientists, physicians, and students to construct ultradense and high-throughput clinical screening metadevices.

Stokes Dynamic Polarimeter for Non-Organic and Organic Samples Characterization

“…The design of biosensors has recently shown a considerable advance in human diagnosis through proteins and enzymes detection that characterize bacteria and virus diseases [ 1 ]. In detecting specific viruses such as SARS-CoV 2 [ 2 ] and more biomedical and clinical diagnoses [ 3 ], some of these biosensors use the polarization of light as a detection technique.…”

Polarization-Independent Multi-Resonance With High Q-Factor for Highly Sensitive Terahertz Sensors Based on All-Dielectric Metasurface

“…This unique property enables metasurfaces to provide an excellent platform for biosensing, from microwave to visible frequencies [12][13][14]. Therefore, the research of THz metasurface biosensor has been widely used in biological solution, microbial detection, tumor cell screening and other biomedical directions [15][16][17]. In order to obtain better detection performance, a highquality factor and ultra-narrow band is particularly crucial for resonance metasurface [18][19].…”

Wafer‐Scale 200 mm Metal Oxide Infrared Metasurface with Tailored Differential Emissivity Response in the Atmospheric Windows

“…Materials with responses tailored to this range have broad applications. In particular, lightweight, low volume, and large-area treatments that are able to control the spectral emissivity profile of surfaces, have been shown to be of interest for thermal management through radiative cooling, [23][24][25] spectrally selective detectors and emitters, [8,[26][27][28][29][30][31][32] infrared imaging, [28,33,34] polarization control, [35][36][37] sensing, [38][39][40][41][42] and defense. [43][44][45][46][47][48][49][50][51][52] Engineering of the electromagnetic properties of materials over the different bands in mid-IR is therefore of considerable interest for controlling the reflectivity, absorption, and emissivity spectral response.…”
