Paper Microfluidics Goes Digital

Advanced Materials, 2014
The first example of so-called "digital microfluidics" (DMF) implemented on paper by inkjet printing is reported. A sandwich enzyme-linked immunosorbent assay (ELISA) is demonstrated as an example of a complex, multistep protocol that would be difficult to achieve with capillary-driven paper microfluidics.

Paper-microfluidic signal-enhanced immunoassays

2022
Over the past decade, paper-based microfluidic devices have become popular for their simplicity and ability to conduct diagnostic tests at a low cost. An important class of diagnostic assays that paper-based analytical devices have been used for is immunoassays. The lateral flow immunoassay (LFIA), of which the home pregnancy test is the most prominent

Synthetic microfluidic paper

2015 28th IEEE International Conference on Micro Electro Mechanical Systems (MEMS), 2015
We introduce a polymer synthetic microfluidic paper for lateral flow devices. The aim is to combine the high surface area of paper, or nitrocellulose, with the repeatability, controlled structure, and transparency of polymer micropillars. Our synthetic paper consists of a dense, high aspect ratio array of transparent pillars that are slanted and ...

Electrochemical paper‐based microfluidic devices

ELECTROPHORESIS, 2015
Self‐pumping porous microfluidic devices have attracted significant interest because of their low cost and broad applicability in point‐of‐care and low resource settings. One limitation of many of the devices is sensitivity and selectivity for detection.

Paper Microfluidics for Cell Analysis

Advanced Healthcare Materials, 2018
AbstractPaper microfluidics has attracted much attention since its first introduction around one decade ago due to the merits such as low cost, ease of fabrication and operation, portability, and facile integration with other devices. The dominant application for paper microfluidics still lies in point‐of‐care testing (POCT), which holds great promise ...

Single-Impact Electrochemistry in Paper-Based Microfluidics

ACS Sensors, 2022
Microfluidic paper-based analytical devices (μPADs) have experienced an unprecedented story of success. In particular, as of today, most people have likely come into contact with one of their two most famous examples─the pregnancy or the SARS-CoV-2 antigen test.

Paper-based digital microfluidics

Microfluidics and Nanofluidics, 2014
In this paper, a new fabrication method for digital microfluidics is proposed. In which, paper, graphite, and adhesive tape are used as substrate, electrodes, and dielectric layer, respectively. The graphite is sprayed over a template on the paper substrate.

Centrifugally enhanced paper microfluidics

2012 IEEE 25th International Conference on Micro Electro Mechanical Systems (MEMS), 2012
Fluid flow in paper is currently limited by capillary forces. Here we show how capillary flow control can be improved by integrating paper sectors in lab-on-a-disc platforms. To this end we combine the rotationally controlled centrifugal force with the capillary action to enable basic liquid handling steps such as blood separation, liquid recirculation,
