Lensless coherent imaging of proteins and supramolecular assemblies: Efficient phase retrieval by the charge flippingalgorithm
Result description
Diffractive imaging using the intense and coherent beam of X-ray free-electron lasers opens new perspectives for structural studies of single nanoparticles and biomolecules.Simulations were carried out to generate 3D oversampled diffraction patterns of non-crystalline biological samples,ranging from peptides and proteins to megadalton complex assemblies,and to recover their molecular structure from nanometer to near-atomic resolutions.Using these simulated data,we show here that iterative reconstructionmethods based on standard and variant forms of the charge flipping algorithm,can efficiently solve the phase retrieval problem and extract a unique and reliable molecular structure.
