In-vivo fast non-linear microscopy reveals intraneuronal transport impairment induced by slight molecular motor imbalances in the brain of zebrafish larvae

Intracellular transport is a vital process, especially in neurons. Axonal transport deficit is found in neurodegenerative diseases. Conventional methods used to measure intraneuronal transport are limited by moderate spatiotemporal resolutions. We…

Identification of NV Centers in Synthetic Fluorescent Nanodiamonds and Control of Defectiveness of Crystallites Using Electron Paramagnetic Resonance

A 100 nm synthetic diamond particle with a large (> 4 ppm) amount of nitrogen vacancy (NV) centers has been studied. The latter exhibit lines associated with forbidden Delta m_s = 2 and allowed Delta m_s = 1 transitions in the electron…

Optical properties of SiV and GeV color centers in nanodiamonds under hydrostatic pressures up to 180 GPa

We investigate the optical properties of silicon-vacancy (SiV) and germanium-vacancy (GeV) color centers in nanodiamonds under hydrostatic pressure up to 180 GPa. The nanodiamonds were synthetized by Si or Ge-doped plasma assisted chemical vapor…

Direct Synthesis of Gold Nanoparticles in Polymer Matrix

We report an original method for directly fabricating gold nanoparticles (Au NPs) in a polymer matrix using a thermal treatment technique and theoretically and experimentally investigate their plasmonic properties. The polymeric-metallic…
