The light interaction with the cell of any part or organ of the body gives useful information regarding the changes in optical properties for different cells. A photonic crystal fiber, selectively filled by the sample cell is proposed to detect the cancer cell based on the refractive index (RI). Upon considering the change of optical properties of the proposed fiber due to different RI of normal and cancer cell, sensitivities are attained of 11,428.57, 17,142.85, 31,428.57, and 34,285.71 nm/RIU for Jurkat, PC12, MCF-7, and MDA-MB-231 cell from the transmission spectrum obtained by the Sagnac interferometer phenomena.

使用基于 Sagnac 干涉仪的光子晶体光纤折射率传感器检测癌细胞

与身体任何部位或器官的细胞的光相互作用提供了有关不同细胞光学特性变化的有用信息。建议使用由样品细胞选择性填充的光子晶体光纤，以根据折射率 (RI) 检测癌细胞。考虑到由于正常细胞和癌细胞的不同 RI 引起的光纤光学特性的变化，Jurkat、PC12、MCF-7 和 MDA-MB 的灵敏度分别为 11,428.57、17,142.85、31,428.57 和 34,285.71 nm/RIU由萨格纳克干涉仪现象获得的透射光谱中的 231 像元。
