Available in PDF, EPUB and Kindle. Book excerpt: Microfluidics is a quickly expanding field with numerous applications. The advent of rapid-prototyping and soft-lithography allow for easy and inexpensive fabrication of microfluidic devices. Fluid manipulation on the microscale allows for new functionalities of devices and components not available on the macroscale. Fluid flows on the microscale are laminar with chemical mixing defined strictly by diffusion allowing us to design microfluidic devices with precise control of fluid flow and chemical concentration. New microfluidic technologies can provide new functionalities for micro-total analysis systems for greater device integration and portability. To expand the utilization of microfluidics, this dissertation discusses new microfluidic techniques and devices. Chapter 2 examines microfluidics for quantitative cell biology. New techniques discussed in this dissertation allow us to use microfluidics to study cellular response on a cell-by-cell basis in stable environments. Part of this chapter includes new architectures for creating chemical concentration gradients in microfluidic devices and their applications cell biology. The rest of Chapter 2 introduces a device which allows for cells to grow to high densities in chemostatic conditions. Chapter 3 introduces the merger of optics and microfluidics named "optofluidics". This subset of microfluidics uses the techniques and materials of microfluidics for optical applications. This dissertation describes optofluidic projects involving light manipulation such as a switch, actuator and lens.

This book was released on 2020-05-31 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: A microfluidic biochip is an engineered fluidic device that controls the flow of analytes, thereby enabling a variety of useful applications. According to recent studies, the fields that are best set to benefit from the microfluidics technology, also known as lab-on-chip technology, include forensic identification, clinical chemistry, point-of-care (PoC) diagnostics, and drug discovery. The growth in such fields has significantly amplified the impact of microfluidics technology, whose market value is forecast to grow from $4 billion in 2017 to $13.2 billion by 2023. The rapid evolution of lab-on-chip technologies opens up opportunities for new biological or chemical science areas that can be directly facilitated by sensor-based microfluidics control. For example, the digital microfluidics-based ePlex system from GenMarkDx enables automated disease diagnosis and can bring syndromic testing near patients everywhere. However, as the applications of molecular biology grow, the adoption of microfluidics in many applications has not grown at the same pace, despite the concerted effort of microfluidic systems engineers. Recent studies suggest that state-of-the-art design techniques for microfluidics have two major drawbacks that need to be addressed appropriately: (1) current lab-on-chip systems were only optimized as auxiliary components and are only suitable for sample-limited analyses; therefore, their capabilities may not cope with the requirements of contemporary molecular biology applications; (2) the integrity of these automated lab-on-chip systems and their biochemical operations are still an open question since no protection schemes were developed against adversarial contamination or result-manipulation attacks. Optimization of Trustworthy Biomolecular Quantitative Analysis Using Cyber-Physical Microfluidic Platforms provides solutions to these challenges by introducing a new design flow based on the realistic modeling of contemporary molecular biology protocols. It also presents a microfluidic security flow that provides a high-level of confidence in the integrity of such protocols. In summary, this book creates a new research field as it bridges the technical skills gap between microfluidic systems and molecular biology protocols but it is viewed from the perspective of an electronic/systems engineer.

This book was released on 2012-10-17 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes a new approach for cell analysis by the rapid developing microfluidic technology. The nominee has made great contributions to develop a new analysis platform which combined microfluidic devices with mass spectrometry to determine the trace compounds secreted by cells. Based on this analysis platform, she studied the specific cell secreting behaviors under controlled microenvironment, of which the secretion compounds were qualified and semi-quantified by mass spectrometry. A novel cell sorting device integrated homogenous porous PDMS membrane was invented to classify cells from real samples based on the size difference. The nominee further studied the signal transmission between different cells, and the signal chemicals were qualitative and quantitative monitored by the analysis platform. This indicates the potential significant application of the new cell analysis platform in medicine screening and early diagnosis.

Download or read book Microfluidic Technologies for Investigating Dynamics based Regulation in S Cerevisiae written by Richard O'Laughlin and published by . This book was released on 2020 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technological advances in molecular biology over the last several decades have enabled researchers to probe the inner workings of living systems at unprecedented scale and resolution. These new capabilities have resulted in the emergence of the field of quantitative biology, which seeks to utilize mathematical modeling along with techniques from systems biology and synthetic biology in order to ascertain the design principles that underlie the structure and function of biological regulatory networks. In pursuit of this goal, it has become clear that heterogeneity at the single-cell level and the dynamics, or time-dependent behavior, of these networks are critical features of a multitude of biological processes. Much of the foundational work establishing the importance of these themes began from the study of microbes such as the budding yeast Saccharomyces cerevisiae. However, even in unicellular organisms such as S. cerevisiae, significant challenges remain in tracking and analyzing single cells over long periods of time, as well as monitoring gene expression dynamics at scale. Development of these capabilities is critical, not only for understanding the cell biology of S. cerevisiae, but also for being able to apply the mechanistic insights obtained from yeast to evolutionarily conserved pathways in higher eukaryotes. In this thesis, I describe the design and application of microfluidic technologies for S. cerevisiae that address these limitations. In Chapter 1, I detail the utility of microfluidic devices and time-lapse fluorescence microscopy for analyzing single cells and recording biological dynamics. In Chapter 2, I describe the development of novel microfluidic devices that enable long-term isolation and tracking of single yeast cells, culminating in a design that can monitor cells over the course of their entire replicative lifespans. In Chapters 3 and 4, I discuss applications of the microfluidic technologies described in Chapter 2. Chapter 3 concerns the discovery of metabolic cycles in flavin fluorescence at the single-cell level, which can oscillate along with and independently of the cell division cycle, persisting even when cellular respiration is blocked. Chapter 4 describes the uncovering of two divergent paths taken by single yeast cells during replicative aging, in which distinct dynamics of heterochromatin silencing at the rDNA region that modulate cellular lifespan can be detected in each group. In Chapter 5, I apply the design principles validated in the construction of microfluidic devices for tracking single cells in order to develop a high-throughput microfluidic platform for recording gene expression dynamics of thousands of yeast strains simultaneously. I demonstrate a proof-of-principle of this technology by monitoring changes in gene expression across more than 4000 yeast strains in real-time during the diauxic shift. The microfluidic devices developed and described herein underscore the importance of single-cell analysis and dynamics-based regulation by elucidating novel sources of heterogeneity at the single-cell level and demonstrating how metabolic, chromatin silencing and gene expression dynamics contribute to the regulation of complex processes such as cell division, replicative aging and growth in changing environments. Further, these technologies establish a foundation upon which future studies can continue to pursue quantitative biology work in yeast, from the single-cell level to the genome scale.

Download or read book Microfluidics for Quantitative Analysis of Cellular and Intercellular Interactions written by Timothy Kwa and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of microfluidics has grown steadily over the last decade and a half, due in part to the large variety of applications for manipulating fluids in nanoliter volumes. Specifically for biomedical engineering, microfluidics has been employed for creating small, well-controlled microenvironments for reliable analysis of small populations of cells. Thus, a thoughtfully designed microfluidic device can be extremely powerful toward assaying various cell functions, including the analysis of the cellular secretome. The focus of this thesis involves creating precisely engineered microfluidic devices to analyze small cell populations contained within carefully considered geometries. By integrating biosensors (electrochemical and optical) with these cellular microenvironments, we can achieve near real-time quantitative analysis of cell-secreted products in response to external stimuli. Combined with computational modeling techniques, we can calculate secretion rates for these products. Moreover, these microenvironments can also serve protective functions and toggle cellular communication, yielding novel information and insights into cellular responses. Through series of experiments such as these, we can develop novel methods for addressing and manipulating cell performance, especially in the context of disease or cellular dysfunction. My work involved microfluidic device design, prototyping, fabrication, and testing to obtain meaningful, quantitative results based on cellular function. Chapter 2 describes a microfluidic device capable of detecting two pro-inflammatory cytokines from cells. In Chapter 3, a reconfigurable microfluidic device was designed to protect cells while regenerating a sensor surface. Chapter 4 describes a microfluidic co-culture of liver cells, monitoring the paracrine interactions between hepatocytes and stellate cells. Chapter 5 reports on the detection of cell-secreted cytokines, analyzed in a reconfigurable device facilitating intercellular communication. In chapter 6, a microfluidic device with integrated valves was designed to assay cellular response to a predictably evolving chemical gradient. These devices with their disparate applications have produced a variety of interesting results pertaining to cellular function and intercellular communication. To this end, future work may be useful for shedding insights into disease pathogenesis and treatment, especially in terms of quantifying dose-dependent responses.
