Terahertz cancer cell sensor based on plasmonic toroidal metasurface
This paper investigates a plasmonic toroidal metasurface cancer cell sensor capable of highly sensitive, cost-effective, and label-free detection. Utilizing titanium and gold split ring resonators, the metasurface unit are formed. Numerical findings indicate a significant resonance frequency shift of the metasurface upon changes in the measured substance, enabling accurate detection of various cancer cell types, such as blood cancer cell and cervical cancer cell in the 2.5 THz-4.5 THz band, with sensitivity reaching 1.075 THz/RIU. Moreover, the metasurface sensor demonstrates superior angular stability and high sensitivity in detecting cyanide and heavy metal-contaminated water. These research outcomes lay a theoretical foundation for the development and application of highly sensitive cancer cell sensors.
期刊介绍：
Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
