A microfluidic passive pumping method relying on surface tension properties is investigated and a physical model developed. When small inlet drop placed the entrance of channel it creates more pressure than large output at exit, causing fluid flow. The behavior input occurs in two characteristic phases. An analytical solution proposed verified by experimental results. We find that during first phase flow rate stable this can be prolonged refilling to produce continuous microchannel.
Although the field of microfluidics has made significant progress in bringing new tools to address biological questions, accessibility and adoption within life sciences are still limited. Open microfluidic systems have potential lower barriers adoption, but absence robust design rules hindered their use. Here, we present an open platform, suspended microfluidics, that uses surface tension fill maintain a fluid microscale structures devoid ceiling floor. We developed simple ubiquitous model...
Microfluidic cell-based systems have enabled the study of cellular phenomena with improved spatiotemporal control microenvironment and at increased throughput. While poly(dimethylsiloxane) (PDMS) has emerged as most popular material in microfluidics research, it specific limitations that prevent microfluidic platforms from achieving their full potential. We present here a complete process, ranging mold design to embossing bonding, describes fabrication polystyrene (PS) devices similar cost...
The utilization of 3D, physiologically relevant in vitro cancer models to investigate complex interactions between tumor and stroma has been increasing. Prior work generally focused on the cells and, role fibroblast culture conditions tumor-stromal cell is still largely unknown. Here, we focus by comparing functional behaviors human mammary fibroblasts (HMFs) cultured 2D 3D their effects invasive progression breast (MCF10DCIS.com). We identified increased levels several paracrine factors...
Open microfluidic capillary systems are a rapidly evolving branch of microfluidics where fluids manipulated by forces in channels lacking physical walls on all sides. Typical channel geometries include grooves, rails, or beams and complex with multiple air–liquid interfaces. Removing allows access for retrieval (fluid sampling) addition (pipetting reagents adding objects like tissue scaffolds) at any point the channel; entire becomes "device-to-world" interface, whereas such interfaces...

Abstract Filamentous fungi differentiate along complex developmental programs directed by abiotic and biotic signals. Currently, intrinsic signals that govern fungal development remain largely unknown. Here we show an endogenously produced secreted oxylipin, 5,8-diHODE, induces cellular differentiation, including lateral branching in pathogenic Aspergillus fumigatus flavus , appressorium formation the rice blast pathogen Magnaporthe grisea . The response is specific to a subset of oxylipins...
Abstract Droplet microfluidics enables compartmentalized reactions in small scales and is utilized for a variety of applications across chemical analysis, material science, biology.
