Design and Analysis of a Novel Nanoscale 2D Photonic Crystal Structure for Enhanced Multi-Disorder Biosensing
A 2D nano-scale multipurpose diamond-shaped ring resonator photonic crystal (PhC) biosensor with 15 × 11 circular silicon (Si) rods in a triangular lattice arrangement is proposed in this article. The distinct feature of the suggested biosensor is the design of a nano-cavity with two different rod radii. The designed biosensor is intended for identifying diabetic blood samples, malaria, and chikungunya virus. The proposed biosensor achieves a high quality factor (QF) of 8080, a high sensitivity (S) of 1108 nm/RIU with a low detection limit (DL) of 9.02 × 10−6 RIU, towards breast cancer analysis. The QF, S, and DL of the biosensor for the diabetic blood sample are 6963, 1087 nm/RIU, and 1.01 × 10−5 RIU respectively. The highest QF and sensitivity of the biosensor are 8561 and 1121.6 nm/RIU respectively, towards malarial detection. A high QF of 9129.4 and a high sensitivity of 1166.9 is achieved for infected plasma towards chikungunya virus detection.
期刊介绍：
The first international journal dedicated to publishing reviews and original articles from this exciting field, the Journal of Biophotonics covers the broad range of research on interactions between light and biological material. The journal offers a platform where the physicist communicates with the biologist and where the clinical practitioner learns about the latest tools for the diagnosis of diseases. As such, the journal is highly interdisciplinary, publishing cutting edge research in the fields of life sciences, medicine, physics, chemistry, and engineering. The coverage extends from fundamental research to specific developments, while also including the latest applications.
