Microfluidic Paper-Based Analytical Device for Histidine Determination

Applied Biochemistry and Biotechnology, 2020
A laminated paper-based analytical device (LPAD) for histidine detection was fabricated from a chromatography filtration paper and laminate films. Histidine recognition was effected by histidyl-tRNA synthetase (HisRS), and its detection was signaled colorimetrically based on the molybdenum blue reaction.

USB powered microfluidic paper‐based analytical devices

ELECTROPHORESIS, 2019
AbstractMicrofluidic paper‐based analytical devices (μPADs) allow user‐friendly and portable chemical determinations, although they provide limited applicability due to insufficient sensitivity. Several approaches have been proposed to address poor sensitivity in μPADs, but they frequently require bulky equipment for power and/or read‐outs.

Blood separation on microfluidic paper-based analytical devices

Lab on a Chip, 2012
A 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 ...

Microfluidic Paper-Based Analytical Device for Particulate Metals

Analytical Chemistry, 2012
A 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
