摘要

本研究阐明了在太赫兹频谱内设计的超材料（MM）生物传感器，以识别皮肤恶性肿瘤。该生物传感器设计包括一个聚酰亚胺（PI）介电层，放置在金属衬底和上表面的金（Au）贴片之间。这种结构安排在3.257太赫兹频率下达到了98.84%的极端吸收效率，伴随着值得注意的质量因子（Q-factor）为325.7和平均质量系数（FOM）为89.7 RIU毒毒学(1)。此外，与早期生物传感器的性能相比，它提供了897 GHz/RIU的平均灵敏度，使其在生物医学应用中非常有利。

Skin Cancer Detection Using a High-Performance Metamaterial Biosensor

This research elucidates a metamaterial (MM) biosensor designed within the terahertz frequency spectrum to identify cutaneous malignancies. The biosensor design includes a polyimide (PI) dielectric layer placed between a metallic substrate and gold (Au) patches on the upper surface. This structural arrangement culminates in an extreme absorption efficiency of 98.84% at a frequency of 3.257 THz, accompanied by a noteworthy quality factor (Q-factor) of 325.7 and an average figure of merit (FOM) of 89.7 RIU⁻¹. Furthermore, compared to the performance of earlier biosensors, it offers an average sensitivity of 897 GHz/RIU, making it highly advantageous for biomedical applications.

期刊介绍： Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons. Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
