Excitation of mitochondria-Endoplasmic reticulum Ca2+ coupling by femtosecond-Laser photostimulation
Publikováno v:
IEEE Photonics Journal, Vol 12, Iss 4, Pp 1-8 (2020)
Mitochondria locate close to endoplasmic reticulum (ER) and cooperate with ER to encode intracellular calcium signaling for cell processes and functions. However, the calcium coupling between mitochondria and ER (mito-ER) remains elusive due to the d

We present a detailed characterization of noise sources in multiple reference optical coherence tomography (MR-OCT) compared to time-domain OCT (TD-OCT). The noise characteristics were modeled based on the TD-OCT noise model and modified for MR-OCT a

A novel method of pixel reassignment (PRA) is proposed to achieve transverse superresolution in the confocal microscopy. Inspired by it, for the first time, we report a pixel-reassigned spectral-domain optical coherence tomography (OCT) with ~1.5 tim

Nondiffracting beams maintain their intensity profiles over a large propagation distance without substantial diffraction and exhibit unique propagation trajectories, leading to scientific impacts in various fields. However, the nonlocalized intensity

The mucosal microanatomy of the large intestine is characterized by the presence of crypts of Lieberkühn, which is associated predominantly with goblet cells. Such cellular-level intestinal microstructures undergo morphological changes during the p

We examine and demonstrate a biosensor using single-mode tapered fiber that has been immobilized with biorecognition molecules to sense targeted proteins. Interaction of evanescent waves with the external medium surrounding the tapered region produce

We analytically calculate the forces generated on the near field by a focused azimuthally polarized Hermite-Gauss beam after passing a complex mask formed by two annular pupils. The resultant optical tractor beam shows two transport channels that mov
