Current Status of Single Particle Imaging with X-ray Lasers

Applied Sciences, 2018
The advent of ultrafast X-ray free-electron lasers (XFELs) opens the tantalizing possibility of the atomic-resolution imaging of reproducible objects such as viruses, nanoparticles, single molecules, clusters, and perhaps biological cells, achieving a ...

Single-particle-sensitive imaging of freely propagating ultracold atoms [PDF]

, 2009
We present a novel imaging system for ultracold quantum gases in expansion. After release from a confining potential, atoms fall through a sheet of resonant excitation laser light and the emitted fluorescence photons are imaged onto an amplified CCD ...

Single Particle Imaging with FEL Using Photon Correlations [PDF]

, 2020
AbstractScattering experiments with femtosecond high-intensity free-electron laser pulses provide a new route to macromolecular structure determination without the need for crystallization at low material usage. In these experiments, the X-ray pulses are scattered with high repetition on a stream of identical single biomolecules and the scattered ...

Hyperspectral darkfield microscopy of single hollow gold nanoparticles for biomedical applications [PDF]

, 2013
Hyperspectral microscopy is a versatile method for simultaneous spatial and spectroscopic characterization of nonfluorescent samples. Here we present a hyperspectral darkfield imaging system for spectral imaging of single nanoparticles over an area of ...

Stripe sensor tomography [PDF]

, 2008
We introduce a general concept of tomographic imaging for the case of an imaging sensor that has a stripelike shape. We first show that there is no difference, in principle, between two-dimensional tomography using conventional electromagnetic or ...

Surface chemistry and morphology in single particle optical imaging

Nanophotonics, 2017
Biological nanoparticles such as viruses and exosomes are important biomarkers for a range of medical conditions, from infectious diseases to cancer. Biological sensors that detect whole viruses and exosomes with high specificity, yet without additional ...

Prospects for single-particle imaging at XFELs [PDF]

Digest of the LEOS Summer Topical Meetings Biophotonics/Optical Interconnects and VLSI Photonics/WBM Microcavities, 2004., 2004
X-ray free-electron lasers will produce pulses of X-rays that are 10 orders of magnitude brighter than today's undulator sources at synchrotrons. This may enable atomic resolution imaging of single macromolecules.

Solution of the phase problem for coherent scattering from a disordered system of identical particles

New Journal of Physics, 2013
While the implementation of single-particle coherent diffraction imaging for non-crystalline particles is complicated by current limitations on photon flux, hit rate and sample delivery, the concept of many-particle coherent diffraction imaging offers an
