Fundamental limits of accuracy and precision in single molecule biosensors [PDF]
arXiv, 2021 Physical limit of molecular sensing has been extensively studied in biological systems. Biosensors are engineered equivalents of molecular sensors in living systems and play critical role in disease diagnosis and management. Investigation into the physical limits of biosensors could have major beneficial impact on early disease diagnosis.

Quantitative Diffractometric Biosensing [PDF]
Phys. Rev. Applied 15, 034023 (2021), 2020 Diffractometric biosensing is a promising technology to overcome critical limitations of refractometric biosensors, the dominant class of label-free optical transducers. These limitations manifest themselves by higher noise and drifts due to insufficient rejection of refractive index fluctuations caused by variation in temperature, solvent ...

Segmentation-free Direct Iris Localization Networks [PDF]
arXiv, 2022 This paper proposes an efficient iris localization method without using iris segmentation and circle fitting. Conventional iris localization methods first extract iris regions by using semantic segmentation methods such as U-Net. Afterward, the inner and outer iris circles are localized using the traditional circle fitting algorithm.

Design of an optimized $\text{MoS}_2$-based highly sensitive near-infrared surface plasmon resonance imaging biosensor [PDF]
IEEE Journal of Selected Topics in Quantum Electronics 2019, 2017 A surface plasmon resonance imaging biosensor based on $\text{MoS}_2$ deposited on Aluminium substrate is designed for high imaging sensitivity and detection accuracy. The proposed biosensor exhibits better performance than graphene-based biosensor in the near-infrared regime. A high imaging sensitivity of more than 970 $\text{RIU}^{-1}$ is obtained at
