Single-Impact Electrochemistry in Paper-Based Microfluidics
ACS Sensors, 2022Microfluidic 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, 2014In 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), 2012Fluid 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,

Paper Microfluidics for Point-of-Care Blood-Based Analysis and Diagnostics.
Analytical Chemistry, 2018Blood is the most intensely studied human biofluid and is used as the main indicator (so-called "gold standard") of the health status of the individual. Blood is also a very complex fluid, containing a multiplicity of components, including cells and cell

Electrochemical Detection for Paper-Based Microfluidics
Analytical Chemistry, 2009We report the first demonstration of electrochemical detection for paper-based microfluidic devices. Photolithography was used to make microfluidic channels on filter paper, and screen-printing technology was used to fabricate electrodes on the paper-based microfluidic devices.

Patterned Photonic Nitrocellulose for Pseudo-Paper Microfluidics.
Analytical Chemistry, 2016We report a pseudo-paper microfluidic chip based on patterned photonic nitrocellulose. The photonic nitrocellulose is fabricated using self-assembled monodisperse SiO2 nanoparticles as template. The SiO2 nanoparticles form a photonic crystal having a close-packed hexagonal structure in the microchannels, so the resulting nitrocellulose has a ...

Smartphone quantifies Salmonella from paper microfluidics
Lab on a Chip, 2013Smartphone-based optical detection is a potentially easy-to-use, handheld, true point-of-care diagnostic tool for the early and rapid detection of pathogens. Paper microfluidics is a low-cost, field-deployable, and easy-to-use alternative to conventional microfluidic devices.
