Quantitative phase imaging (QPI) is a label-free microscopy approach using the phase shift of light as it passes through transparent objects, like mammalian cells, to quantify biomass distribution and changes in biomass over time and space. QPI has seen immense interest and advances in hardware and software leading to numerous applications in biology and expansions in utility within the last decades. This dissertation presents a subset of those studies applied to questions of cellular biology and biophysics along with an overview of the QPI field as whole. The initial proportion of this thesis is devoted to modeling and dissecting various biomechanical properties of cellular mechanics including cellular viscoelasticity and work across varying cell types and biological perturbations using purely QPI. This is followed by an in-depth review of the field of QPI including the development and lineages of the various QPI approaches along with the advances in QPI made in the field of cellular biology, biophysics, and diagnostics. Finally, we conclude this thesis with a review of the ongoing technical and biological advances made in QPI along with perspectives on the directions that QPI field maybe proceeding towards. Demonstrating that QPI is not only a robust tool in probing cellular biology and biophysics already but is also expanding its' capabilities towards more applications in and interrogating fundamental questions about biology.

This book deals with the latest achievements in the field of optical coherent microscopy. While many other books exist on microscopy and imaging, this book provides a unique resource dedicated solely to this subject. Similarly, many books describe applications of holography, interferometry and speckle to metrology but do not focus on their use for microscopy. The coherent light microscopy reference provided here does not focus on the experimental mechanics of such techniques but instead is meant to provide a users manual to illustrate the strengths and capabilities of developing techniques. The areas of application of this technique are in biomedicine, medicine, life sciences, nanotechnology and materials sciences.

This book introduces time-stretch quantitative phase imaging (TS-QPI), a high-throughput label-free imaging flow cytometer developed for big data acquisition and analysis in phenotypic screening. TS-QPI is able to capture quantitative optical phase and intensity images simultaneously, enabling high-content cell analysis, cancer diagnostics, personalized genomics, and drug development. The authors also demonstrate a complete machine learning pipeline that performs optical phase measurement, image processing, feature extraction, and classification, enabling high-throughput quantitative imaging that achieves record high accuracy in label -free cellular phenotypic screening and opens up a new path to data-driven diagnosis.

In this thesis, quantitative phase imaging (QPI) techniques including 2D and 3D versions are investigated and presented. With QPI, biophysical and biochemical information of transparent biological micro-specimens can be measured and quantified. 2D quantitative phase maps of cell samples on the one hand can retrieve morphological shapes, and on the other hand can be converted to dry mass values, which are important bio-markers for cell growth studies. By adapting QPI system into an image cytometer, termed Quantitative phase cytometer (QPC), a large population of ~ 104 HeLa cells were characterized with single-cell level morphology information and dry mass histogram. Next, in order to gain more accurate information such as nuclear shape, nuclear dry mass, and nuclear-to-cytoplasm volume ratio, 3D tomographic versions of QPI, i.e., tomographic phase microscopy (TPM), was introduced, which extended the QPI technique from 2D to 3D in imaging capability. To augment the throughput of TPM system, a digital micro-mirror device (DMD) was used to provide the angle scanning illumination, which significantly boosts the angle scanning speed to the magnitude of kHz. However, this angle scanning method suffers from the diffraction noise caused by the binary grating pattern, which significantly deteriorates the imaging quality. To solve this problem, a novel dynamic spatial filtering method was proposed to perfectly eliminate the diffraction noise for DMD based high-speed angle-scanning TPM systems. In summary, the QPI techniques in 2D and 3D modalities provide a promising quantitative tool for label-free characterization of biological samples.

Quantitative bioimaging is a broad interdisciplinary field that exploits tools from biology, chemistry, optics, and statistical data analysis for the design and implementation of investigations of biological processes. Instead of adopting the traditional approach of focusing on just one of the component disciplines, this textbook provides a unique introduction to quantitative bioimaging that presents all of the disciplines in an integrated manner. The wide range of topics covered include basic concepts in molecular and cellular biology, relevant aspects of antibody technology, instrumentation and experimental design in fluorescence microscopy, introductory geometrical optics and diffraction theory, and parameter estimation and information theory for the analysis of stochastic data. Key Features: Comprises four parts, the first of which provides an overview of the topics that are developed from fundamental principles to more advanced levels in the other parts. Presents in the second part an in-depth introduction to the relevant background in molecular and cellular biology and in physical chemistry, which should be particularly useful for students without a formal background in these subjects. Provides in the third part a detailed treatment of microscopy techniques and optics, again starting from basic principles. Introduces in the fourth part modern statistical approaches to the determination of parameters of interest from microscopy data, in particular data generated by single molecule microscopy experiments. Uses two topics related to protein trafficking (transferrin trafficking and FcRn-mediated antibody trafficking) throughout the text to motivate and illustrate microscopy techniques. An online appendix providing the background and derivations for various mathematical results presented or used in the text is available at http://www.routledge.com/9781138598980.
