Maskless, rapid manufacturing of glass microfluidic devices using a picosecond pulsed laser.

Conventional manufacturing of glass microfluidic devices is a complex, multi-step process that involves a combination of different fabrication techniques, typically photolithography, chemical/dry etching and thermal/anodic bonding. As a result, the process is time-consuming and expensive, in particular when developing microfluidic prototypes or even manufacturing them in low quantity. This report describes a fabrication technique in which a picosecond pulsed laser system is the only tool required to manufac...

Methods for analysis of complex survey data: an application using the Tanzanian 2015 Demographic and Health Survey and Service Provision Assessment.

Low-income and middle-income countries (LMICs) seek to better utilize household and health facility survey data for monitoring and evaluation, as well as for health program planning. However, analysis of this complex survey data are complicated. In Tanzania, the National Evaluation Platform project sought to analyze Demographic and Health Survey (DHS) data and Service Provision Assessment (SPA) data as part of an evaluation of the national One Plan for Maternal and Child Health.

Real-time pressure monitoring system for microfluidic devices using deformable colloidal crystal membrane.

Understanding the hydrodynamic behavior in microfluidic devices is crucial for utilization of these systems in lab-on-a-chip applications. However, hydrodynamic capacitance in microfluidic devices causes a delay and mismatch between the applied pressure and actual pressure in the microchannel. Therefore, real-time monitoring of the site-specific internal pressure in microchannels is important for designing the operating conditions of the system. We introduce a deformable colloidal crystal membrane composed ...

Microfluidics: Innovations in Materials and Their Fabrication and Functionalization.

Microfluidics is a growing field of study because these devices offer novel and versatile approaches for addressing a range of scientific problems. Microfluidics have been used in separations, cell analysis, and microreactors, to illustrate a few applications. Microfluidics have been defined in terms of microliter volumes or micrometer dimensions of channels. For this review, we utilize the latter definition, where microfluidic channels range from 1-1000 µm in width or height. Microfluidic devices are fabr...

On-chip organic synthesis enabled using an engine-and-cargo system in an electrowetting-on-dielectric digital microfluidic device.

This paper presents a microfluidic chemical reaction using an electrowetting-on-dielectric (EWOD) digital microfluidic device. Despite a number of chemical/biological applications using EWOD digital microfluidic devices, their applications to organic reactions have been seriously limited because most of the common solvents used in synthetic organic chemistry are not compatible with EWOD devices. To address this unsolved issue, we first introduce a novel technique using an "engine-and-cargo" system that enab...

In this paper, we demonstrated the fabrication of wood-based microfluidic devices and their adaptability for single-use, point-of-care (POC) applications. These devices are made from easily sourced renewable materials for fabrication while exhibiting all the advantages of plastic devices without the problem of non-biodegradable waste and cost. To build these wood devices, we u...

Schistosomiasis - Assessing Progress toward the 2020 and 2025 Global Goals.

With the vision of "a world free of schistosomiasis," the World Health Organization (WHO) set ambitious goals of control of this debilitating disease and its elimination as a public health problem by 2020 and 2025, respectively. As these milestones become imminent, and if programs are to succeed, it is important to evaluate the WHO programmatic guidelines empirically.

Estimate of safety impact of lane keeping assistant system on fatalities and injuries reduction for China: Scenarios through 2030.

The objective of this research is to assess the number of casualties in China's road traffic accidents that can be reduced by lane keeping assistant (LKA) through 2030, based on the historical data on the number of fatalities and injuries in China and the proportion of LKA planed in China policy. The analysis was divided into 4 main parts: (1) Predict injuries and fatalities caused by traffic accident in China without LKA through 2030; (2) Apply the methodology to estimate the percentage reduction in injuri...

Parallelizable microfluidic dropmakers with multilayer geometry for the generation of double emulsions.

Microfluidic devices enable the production of uniform double emulsions with control over droplet size and shell thickness. However, the limited production rate of microfluidic devices precludes the use of monodisperse double emulsions for industrial-scale applications, which require large quantities of droplets. To increase throughput, devices can be parallelized to contain many dropmakers operating simultaneously in one chip, but this is challenging to do for double emulsion dropmakers. Production of doubl...

Microfluidic systems for cancer diagnostics.

Although not employed in the clinic as of yet, microfluidic systems are likely to become a key technology for cancer diagnostics and prognosis. Microfluidic devices have been developed for the analysis of various biomarkers including circulating tumor cells, cell-free DNA, exosomes, and proteins, primarily in liquid biopsies such as serum, plasma, and whole blood, avoiding the need for tumor tissue biopsies.

Manipulating and studying triglyceride droplets in microfluidic devices.

Triglyceride is the main lipid class in nature, found as droplets in both living systems and man-made products (such as manufactured foods and drugs). Characterizing triglyceride droplets in situ in these systems is complex due to many environmental interactions. To answer basic research questions about droplet formation, structuration, stability, or degradation, microfluidic strategies were developed, allowing well-controlled droplets to be formed, manipulated, and studied. In this review, these strategies...

Spatiotemporal pattern of glucose in a microfluidic device depend on the porosity and permeability of the medium: A finite element study.

Glucose plays an important role as a source of nutrients and influence cellular processes such as differentiation, proliferation and migration. In vitro models based on microfluidic devices represent an alternative to study several biological processes in a more reproducible and controllable method compared to in vivo models. Glucose concentration across a microfluidic chip and its behavior in experimental conditions is not completely understood.

Characterizing the impact of thermal gels on isotachophoresis in microfluidic devices.

Thermally reversible Pluronic gels have been employed as separation matrices in microfluidic devices in the analysis of biological macromolecules. The phase of these gels can be tuned between liquid and solid states using temperature to vary fluidic resistance and alter peak resolution. Although separations in thermal gels have been characterized, their effect on isotachophoresis has not. This study used fluorescein as a model analyte to evaluate isotachophoretic preconcentration as a function of thermal po...

Undernutrition among under-five children in Ethiopia is a prominent public health concern, and it lacked attention for decades. However, the government of Ethiopia, together with other stakeholders, committed to overcoming the impact of malnutrition through the transformational plan. Here we show the magnitude of undernutrition among under-five children and t...

Open-source, 3D-printed Peristaltic Pumps for Small Volume Point-of-Care Liquid Handling.

Microfluidic technologies are frequently employed as point-of-care diagnostic tools for improving time-to-diagnosis and improving patient outcomes in clinical settings. These microfluidic devices often are designed to operate with peripheral equipment for liquid handling that increases the cost and complexity of these systems and reduces their potential for widespread adoption in low resource healthcare applications. Here, we present a low-cost (~$120), open-source peristaltic pump constructed with a combin...
