Nitric oxide (NO) is a ubiquitous, volatile, cellular signaling molecule that operates across a
wide physiological concentration range (pM–µM) in different tissues. It is a highly diffusible …

In this article, we provide a review of fabrication platforms and state of the art developments
in the area of silicon nitride photonic integrated circuits (PICs) for the visible wavelength …

Nanotechnology-based antioxidants and therapeutic agents are believed to be the next
generation tools to face the ever-increasing cancer mortality rates. Graphene stands as a …

Crystallography has been the routine technique for studying high-resolution structures of
proteins for over five decades. A major bottleneck in structure determination of …

Label‐free optical nano‐imaging of dendritic structures and intracellular granules in
biological cells is demonstrated using a bright and homogeneous nanometric light source …

Fluidic channels were employed to induce the self-assembly of poly (ethylene glycol)-b-
polystyrene into polymeric vesicles and nanotubes. The laminar flow in the device enables …

We present label-free and high spatial-resolution imaging for specific cellular structures
using an electron-beam excitation-assisted optical microscope (EXA microscope). Images of …

Electron microscopy studies have demonstrated that the diameter of a focused electron
beam is small enough to probe or manipulate subcellular domains of a single biological cell …

High-resolution imaging of the surfaces of samples can be performed using near-field
optical microscopes by scanning a small light spot; however, structures located deep …

We demonstrated that the high spatial resolution absorption contrast imaging of the crystal of
vitamin B9 has absorption at ultraviolet wavelengths. The absorption wavelength matches …
