This dissertation discusses advancements in open channel microfluidics, the design and fabrication of open channels and capillary pumps, and methods to manipulate open channels. An open droplet-based microfluidics platform is demonstrated with promising future applications. Additionally, an expression to measure the velocity of capillary flow in an open channel and design guidelines for an efficient capillary pump are presented.Chapter 1 discusses the field of microfluidics and the advantages of such platforms. The fundamentals of open microfluidics is presented along with the benefits of open channel systems. Capillary flow is discussed, and the necessary considerations for fabrication of channels to ensure that the fluid in the system is driven by capillary means is provided. Droplet-based microfluidics is a large subfield of microfluidics, which is briefly reviewed, and a need for further fundamental and applied work using droplet-based systems which are completely driven by capillary flow is discussed. Finally, capillary pumps provide a solution to the inherent decrease of velocity (and flow rate) observed in channels driven by capillary flow. Chapter 2 introduces droplet-based microfluidics where droplets are formed in an open channel that is completely driven by capillary means. Our work represents the first time that this phenomenon was observed and studied. The interaction that exists between a droplet and the surrounding phase is described in detail. Chapter 3 explores fundamental microfluidic features in open channels: droplet splitting, multiple droplets, and droplet merging. An example of an open platform that enables users to manipulate droplets on the same chip is presented. Chapter 4 investigates capillary flow in an open channel, and an expression to measure velocity derived from the Lucas-Washburn-Rideal law is presented. The capillary flow in bifurcations and networks of open channels are studied. Chapter 5 investigates the theory of open capillary pumps to alleviate the inherent decrease of velocity and flow rate during capillary flow. Design guidelines of an efficient open capillary pump are discussed. Chapter 6 concludes the thesis with an overall perspective of the field and other experimental proposals to improve the overall design of open channels and capillary pumps and to enable applications with the platform.

Open microfluidics, the study of microflows having a boundary with surrounding air, encompasses different aspects such as paper or thread-based microfluidics, droplet microfluidics and open-channel microfluidics. Open-channel microflow is a flow at the micro-scale, guided by solid structures, and having at least a free boundary (with air or vapor) other than the advancing meniscus. This book is devoted to the study of open-channel microfluidics which (contrary to paper or thread or droplet microfluidics) is still very sparsely documented, but bears many new applications in biology, biotechnology, medicine, material and space sciences. Capillarity being the principal force triggering an open microflow, the principles of capillarity are first recalled. The onset of open-channel microflow is next analyzed and the fundamental notion of generalized Cassie angle (the apparent contact angle which accounts for the presence of air) is presented. The theory of the dynamics of open-channel microflows is then developed, using the notion of averaged friction length which accounts for the presence of air along the boundaries of the flow domain. Different channel morphologies are studied and geometrical features such as valves and capillary pumps are examined. An introduction to two-phase open-channel microflows is also presented showing that immiscible plugs can be transported by an open-channel flow. Finally, a selection of interesting applications in the domains of space, materials, medicine and biology is presented, showing the potentialities of open-channel microfluidics.

Open microfluidics or open-surface is becoming fundamental in scientific domains such as biotechnology, biology and space. First, such systems and devices based on open microfluidics make use of capillary forces to move fluids, without any need for external energy. Second, the "openness" of the flow facilitates the accessibility to the liquid in biotechnology and biology, and reduces the weight in space applications. This book has been conceived to give the reader the fundamental basis of open microfluidics. It covers successively The theory of spontaneous capillary flow, with the general conditions for spontaneous capillary flow, and the dynamic aspects of such flows. The formation of capillary filaments which are associated to small contact angles and sharp grooves. The study of capillary flow in open rectangular, pseudo-rectangular and trapezoidal open microchannels. The dynamics of open capillary flows in grooves with a focus on capillary resistors. The case of very viscous liquids is analyzed. An analysis of suspended capillary flows: such flows move in suspended channels devoid of top cover and bottom plate. Their accessibility is reinforced, and such systems are becoming fundamental in biology. An analysis of “rails” microfluidics, which are flows that move in channels devoid of side walls. This geometry has the advantage to be compatible with capillary networks, which are now of great interest in biotechnology, for molecular detection for example. Paper-based microfluidics where liquids wick flat paper matrix. Applications concern bioassays such as point of care devices (POC). Thread-based microfluidics is a new domain of investigation. It is seeing presently many new developments in the domain of separation and filtration, and opens the way to smart bandages and tissue engineering. The book is intended to cover the theoretical aspects of open microfluidics, experimental approaches, and examples of application.

To counter lubricant shortage at a frictional contact (starvation), lubrication liquids, e.g. oils, are actively transported from a distant location towards the undersupplied tribocontact. This is done via small channels or generally via structures cut into a flat surface. In this way one can use capillary force as a cheap and reliable driver of the lubricant flow. Numerical modeling and experiments show that this method can be considered a promising new option to enhance tribocontact operation.
