How do you make paper microfluidics?
Overview. Wax printing microfluidics uses a printer to deposit a layer of wax onto paper. This wax is then impregnated into the paper by laminating the printed paper between two sheets of plastic that act as a protective barrier for the wax.
How does paper based microfluidics work?
Paper-based microfluidics are microfluidic devices that consist of a series of hydrophilic cellulose or nitrocellulose fibers that transport fluid from an inlet through the porous medium to a desired outlet or region of the device, by means of capillary action.
What is the role of paper patterning with wax barrier boundary?
(a) Wax patterning on a paper substrate, followed by heating step, to create hydrophobic borders across the substrate. (b) A typical example of a μPAD device for the minimum hydrophobic barrier test. Black boundaries show printed wax which prevents liquid to flow out of channel.
What is a MicroPad?
µPad (MicroPad) is an open digital note taking app. Taking notes is a fundamentally important task, especially for students. However, most powerful note-taking apps lock you into their platform. µPad is open source and free. It uses the Open Notepad XML (NPX) file format and can export to Markdown-formatted plain text.
What is continuous flow microfluidics?
Continuous flow microfluidics is the manipulation of liquid flow through fabricated microchannels without breaking continuity. Fluid flow is established by external sources such as micropumps (e.g., peristaltic or syringe pumps) or internal mechanisms such as electric, magnetic or capillary forces.
What is microfluidic paper-based analytical devices?
Microfluidic paper-based analytical devices (μPADs) are a new class of point-of-care diagnostic devices that are inexpensive, easy to use, and designed specifically for use in developing countries.
What is microfluidic paper based analytical devices?
What is the advantage of microfluidics?
The advantages of microfluidic cell culture include the ability to more closely mimic a cell’s natural microenvironment, for example by continuous perfusion culture or by creating chemical gradients, and to study low numbers of cells or single cells in high temporal and/or spatial resolution via automation.
Why is microfluidics useful?
Microfluidics allow the analysis and use of less volume of samples, chemicals and reagents reducing the global fees of applications. Many operations can be executed at the same time thanks to their compact size, shortening the time of experiment.
Which of the following process will be used to cut the paper sheets for microfluidic applications?
3.1. Paper cutting is one of the simplest and oldest techniques for fabricating channels out of paper. In this fabrication process, paper is cut into a network of channels and zones using a programmable knife cutter (cutting plotter) or a laser cutter (CO2 laser).
What are the advantages of Microfluidics?
The reduced turnaround time and increased productivity with a small device footprint allows for ease of integration into a variety of experimental setups. The increased portability makes it ideal for point-of-care devices. The ease of use and low production cost also make microfluidic devices attractive.
What is paper analytical device?
Paper-based analytical devices are being utilized as biosensors and immunoassays for detecting biological analytes associated with disease. The technology is also being employed for testing contaminated food in order to reduce rates of infections caused by foodborne pathogens.
What is the future of Microfluidics?
As well as laboratory-based research, the future of microfluidic devices is likely to involve their direct integration with the human body. This poses several challenges, not least the basic incompatibility between solid electrical components, and the flexible, dynamic nature of tissue.
What is microfluidic paper-based analytical device?
What is microfluidics technology?
Microfluidics is the science and technology of systems that process or manipulate small amounts of fluidics (10−9 to 10−18L), using channels measuring from tens to hundreds of micrometers.

Is it possible to fabricate paper-based microfluidics?
In this study, fabrication of paper-based microfluidics was demonstrated by spray on the printed paper. Different from the normally used filter papers, printing paper, which is much more accessible and cheaper, was utilized as the substrate material.
