3D Printed Paper-Based Microfluidic Analytical Devices
As a pump-free and lightweight analytical tool, paper-based microfluidic analytical devices (μPADs) attract more and more interest. If the flow speed of μPAD can be programmed, the analytical sequences could be designed and they will be more popular. This reports presents a novel μPAD, driven by the capillary force of cellulose powder, printed by a desktop three-dimensional (3D) printer, which ...
متن کاملHollow-channel paper analytical devices.
We present a microfluidic paper analytical device (μPAD) that relies on flow in hollow channels, rather than through a cellulose network, to transport fluids. The flow rate in hollow channels is 7 times higher than in regular paper channels and can be conveniently controlled from 0 to several mm/s by balancing capillary and pressure forces. More importantly, the pressure of a single drop of liq...
متن کاملAdvances on paper - based analytical devices ( μ PADs ) – literature review
Microfluidic paper-based analytical devices (μPADs) are relatively new group of analytical tools. Work principles of such devices partially evolved from chromatographic techniques, particularly planar chromatography. Recently, analytical devices based on paper are subject of extensive research, mostly focused on fast and non-expensive biochemical analysis but also for screening of medical and e...
متن کاملAnalytical Devices Based on Direct Synthesis of DNA on Paper.
This paper addresses a growing need in clinical diagnostics for parallel, multiplex analysis of biomarkers from small biological samples. It describes a new procedure for assembling arrays of ssDNA and proteins on paper. This method starts with the synthesis of DNA oligonucleotides covalently linked to paper and proceeds to assemble microzones of DNA-conjugated paper into arrays capable of simu...
متن کاملDiagnostics for the developing world: microfluidic paper-based analytical devices.
Microfluidic paper-based analytical devices (microPADs) are a new class of point-of-care diagnostic devices that are inexpensive, easy to use, and designed specifically for use in developing countries.
