Download or read book Improving the Precision and Accuracy of Three dimensional Single molecule Localization Microscopy written by Petar Nikolov Petrov and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of the point spread function (PSF) of a microscope allows point sources of light such as single molecules and particles to be localized in space with a precision on the order of tens of nanometers or better. Single-molecule localization microscopy (SMLM) leverages this to enable both tracking of single molecules to study their dynamics as well as super-resolution imaging of static objects labeled with fluorescent molecules to reveal their structure. Since localization entails estimating parameters of the molecule from its PSF, the precision and accuracy with which those parameters can be determined are of fundamental importance to the quality of the results in a localization experiment. The work presented in this Dissertation seeks to improve the precision and accuracy of single-molecule localization through developments in computational tools, optical design, and calibration methods. Special attention is paid to the localization of engineered PSFs, in which the PSF shape is deliberately altered to encode information such as three-dimensional (3D) molecular position or orientation of the molecular dipole. The first two Chapters in this Dissertation serve as introductions. Chapter 1 presents general background on a variety of topics relevant to single-molecule localization microscopy. In Chapter 2, the theory underlying image formation in single-molecule fluorescence microscopy is presented, with a special focus on aberrations and engineered PSFs, which play a crucial role throughout the Dissertation. Chapter 3 of this Dissertation reviews the experimental methods employed in this Dissertation. This includes the optical designs employed for illuminating molecules and detecting their fluorescence, as well as descriptions of the instrument control procedures and a detailed walkthrough of the image analysis and localization procedures employed throughout the remaining Chapters. The primary results presented in this Dissertation are the subject of Chapters 4-7. The first two of these focus on the improvement of localization precision. In Chapter 4, it is shown that models of the tetrapod PSF derived from diffraction theory calculations are not sufficient to enable precise 3D localization of single emitters. A method of phase retrieval is demonstrated which enables the determination of a more realistic PSF model, informed by experimental measurements, and allows for recovery of the localization precision to nearly its theoretical limit. Chapter 5 presents a complementary approach to improving localization precision based on illumination with a tilted light sheet excitation beam instead of conventional wide-field illumination to achieve optical sectioning of samples several microns thick. Combination of this illumination strategy with the double helix PSF is shown to improve the signal-to-background ratio and enable 3D single-molecule super-resolution imaging of large structures within mammalian cells with superior localization precision. In the final two Chapters of this Dissertation, the theme shifts from localization precision to localization accuracy. Chapter 6 describes an experimental study of the PSF near the interface between an aqueous sample medium and a glass coverslip. Refraction of collected fluorescence through this interface gives the PSF a depth-dependent shape leading to a distortion of axial position estimates as well as an apparent rescaling of the focal position, both of which limit the accuracy of 3D localization microscopy. These effects are carefully characterized using a calibration standard I developed which provides ground truth. Finally, Chapter 7 addresses an orientation-dependent lateral bias in the PSF which is induced by the anisotropy of the dipole radiation patterns of single molecules. An experimental approach based on polarization filtering is shown to remove the bias by rejecting the component of emitted light which is radially-polarized in the Fourier plane of the microscope, producing a PSF which enables unbiased estimation of the lateral position and azimuthal orientation of the molecule.

Download or read book Fluorescence Imaging Microscopy Studies on Single Molecule Diffusion and Photophysical Dynamics written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the last years, e.g. by investigating the fluorescence of single molecules in biological cells, remarkable progress has been made in cell biology extending conventional ensemble techniques concerning temporal / spatial resolution and the detection of particle subpopulations [82]. In addition to employing single fluorophores as "molecular beacons" to determine the position of biomolecules, single molecule fluorescence studies allow to access the photophysical dynamics of genetically encoded fluorescent proteins itself. However, in order to gain statistically consistent results, e.g. on the mobility behavior or the photophysical properties, the fluorescence image sequences have to be analyzed in a preferentially automated and calibrated (non-biased) way. In this thesis, a single molecule fluorescence optical setup was developed and calibrated and experimental biological in-vitro systems were adapted to the needs of single molecule imaging. Based on the fluorescence image sequences obtained, an automated analysis algorithm was developed, characterized and its limits for reliable quantitative data analysis were determined. For lipid marker molecules diffusing in an artifcial lipid membrane, the optimum way of the single molecule trajectory analysis of the image sequences was explored. Furthermore, effects of all relevant artifacts (specifically low signal-to-noise ratio, finite acquisition time and high spot density, in combination with photobleaching) on the recovered diffusion coefficients were carefully studied. The performance of the method was demonstrated in two series of experiments. In one series, the diffusion of a fluorescent lipid probe in artificial lipid bilayer membranes of giant unilamellar vesicles was investigated. In another series of experiments, the photoconversion and photobleaching behavior of the fluorescent protein Kaede-GFP was characterized and protein subpopulations were identified.

Download or read book Time dependent Problems in Imaging and Parameter Identification written by Barbara Kaltenbacher and published by Springer Nature. This book was released on 2021-02-23 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inverse problems such as imaging or parameter identification deal with the recovery of unknown quantities from indirect observations, connected via a model describing the underlying context. While traditionally inverse problems are formulated and investigated in a static setting, we observe a significant increase of interest in time-dependence in a growing number of important applications over the last few years. Here, time-dependence affects a) the unknown function to be recovered and / or b) the observed data and / or c) the underlying process. Challenging applications in the field of imaging and parameter identification are techniques such as photoacoustic tomography, elastography, dynamic computerized or emission tomography, dynamic magnetic resonance imaging, super-resolution in image sequences and videos, health monitoring of elastic structures, optical flow problems or magnetic particle imaging to name only a few. Such problems demand for innovation concerning their mathematical description and analysis as well as computational approaches for their solution.
