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.

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.

Quantitative phase imaging using Digital Holographic Microscopy (DHM) is emergine as a label-free and wide-field method of characterizing cells with high spatio-temporal resolution. In parallel, silicon based michromechanical and electronic devices are allowing both manipulation (e.g. electrical stimulation, mechanical actuation) as well as characterization (electrical and mechanical) of micro and nano-scopic samples. THis has revolutionized development of lab-on-a-chip devices for high throughput analysis of cells and molecules for diagnosis of disease and screening of drug-effects. However, very little progress has been made in optical (e.g. fluorescence, Raman etc) characterization of samples on these silicon-based devices. Especially, wide-field high-resolution optical imaging and characterization of samples under silicon environment has not been possible owing to the opacity of silicon to visible light. This thesis reports high resolution near-infrared quantitative phase imaging of cells through silicon, in isotonic as well as hypotonic environment using DHM. Further, several microscopic (AFM, laser manipulation) methods are being developed for characterization of mechanical properties (e.g. elasticity) of cells so as to determine changes during physiological stress. In particular, optical tweezers are used for transverse-stretching cells by actuating anchored-beads as handles and imaging using phase-contrast microscopy. While this method is constantly gaining more attention due to non-contact nature of actuation, it is very time consuming and has low working distance. The thesis describes development of a weakly-focused laser beam for axial-stretching. Application of DHM allowed cell imaging with nm-resolution when stretched axially. Development of an empirical formula for force exerted by defocused light beam on a cell surface led to measurement of elastic property of cell. In addition to this, the thesis aimed at evaluating changes in elastic properties of cell under over-expression of certain proteins (HOX-B9), which is believed to be involved in tumorigenesis. Significant reduction in elastic property of cells over-expressing HOXB9 was found as compared to the control cells. Thus, the thesis paves the way for development of a method for optical manipulation and imaging of cells for characterization of their elastic properties in different physiological states, and probe nanoscale interatctions with different physio-chemical agents in a non-invasis and label-free manner.

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.
