Classical and Quantum Surface Plasmon Resonance Biosensing

International Journal of Optics, 2023
Surface plasmon resonance is an optical phenomenon first discovered in 1902. The phenomenon has since had many applications, particularly in biosensing. In this paper, we review surface plasmon resonance-based biosensing, look at recent progress made in ...

Study of the Binding of Cuminaldehyde with Bovine Serum Albumin by Spectroscopic and Molecular Modeling Methods

Journal of Spectroscopy, 2023
Here, we investigated the interaction of cuminaldehyde with a model carrier protein, bovine serum albumin (BSA). The formation of the BSA–cuminaldehyde complex was confirmed through ultraviolet–visible (UV–Vis) spectroscopy and further proven by detailed

Vector diffraction based on 3D Huygens-Fresnel principle and vector decomposition in Cartesian coordinate

Results in Optics
We proposed vector diffraction equations based on 3D Huygens-Fresnel principle and vector decomposition in Cartesian coordinate. Our expression should more accurate than classical Richards-Wolf diffraction, because the deduction of Richards-Wolf ...
