Blood separation on microfluidic paper-based analytical devices
Lab on a Chip, 2012A microfluidic paper-based analytical device (μPAD) for the separation of blood plasma from whole blood is described. The device can separate plasma from whole blood and quantify plasma proteins in a single step. The μPAD was fabricated using the wax dipping method, and the final device was composed of a blood separation membrane combined with ...

Polysaccharides as protectants for paper-based analytical devices with antibody
Talanta, 2017Paper with immobilized protein can provide a low-cost platform for diagnostics, but evidence is emerging that the instability of protein on paper during shipping and storage severely limits its commercial development. Of these, paper-immobilized antibody, though widely used, is in urgent need of improvement in the shelf life.

Microfluidic Paper-Based Analytical Device for Particulate Metals
Analytical Chemistry, 2012A microfluidic paper-based analytical device (μPAD) fabricated by wax printing was designed to assess occupational exposure to metal-containing aerosols. This method employs rapid digestion of particulate metals using microliters of acid added directly to a punch taken from an air sampling filter. Punches were then placed on a μPAD, and digested metals
