Start-to-end simulation of single-particle imaging using ultra-short pulses at the European X-ray Free-Electron Laser [PDF]

open access: yesIUCrJ, 2017
Single-particle imaging with X-ray free-electron lasers (XFELs) has the potential to provide structural information at atomic resolution for non-crystalline biomolecules.

Is radiation damage the limiting factor in high-resolution single particle imaging with X-ray free-electron lasers? [PDF]

open access: yesStructural Dynamics, 2019
The prospect of single particle imaging with atomic resolution is one of the scientific drivers for the development of X-ray free-electron lasers. The assumption since the beginning has been that damage to the sample caused by intense X-ray pulses is one

Single-particle imaging of nanomedicine entering the brain. [PDF]

open access: yesProc Natl Acad Sci U S A
Nanomedicine has emerged as a revolutionary strategy of drug delivery. However, fundamentals of the nano–neuro interaction are elusive. In particular, whether nanocarriers can cross the blood–brain barrier (BBB) and release the drug cargo inside the brain, a basic process depicted in numerous books and reviews, remains controversial.

Single Particle X-ray Diffractive Imaging [PDF]

open access: yesNano Letters, 2007
In nanotechnology, strategies for the creation and manipulation of nanoparticles in the gas phase are critically important for surface modification and substrate-free characterization. Recent coherent diffractive imaging with intense femtosecond X-ray pulses has verified the capability of single-shot imaging of nanoscale objects at suboptical ...

MRI detection of single particles for cellular imaging [PDF]

open access: yesProceedings of the National Academy of Sciences, 2004
There is rapid growth in the use of MRI for molecular and cellular imaging. Much of this work relies on the high relaxivity of nanometer-sized, ultrasmall dextran-coated iron oxide particles. Typically, millions of dextran-coated ultrasmall iron oxide particles must be loaded into cells for efficient detection.

The role of transient resonances for ultra-fast imaging of single sucrose nanoclusters

open access: yesNature Communications, 2020
X-ray free electron lasers provide high photon flux to explore single particle diffraction imaging of biological samples. Here the authors present dynamic electronic structure calculations and benchmark them to single-particle XFEL diffraction data of ...

Isotropic resolution in fluorescence imaging by single particle reconstruction [PDF]

open access: yes2016 IEEE 13th International Symposium on Biomedical Imaging (ISBI), 2016
Low axial resolution is a major limitation of fluorescence imaging modalities. We propose a methodology to achieve high isotropic resolution by reconstructing fluorescence volumes from observations of multiple particle replicates with different orientations.
