Microfluidic Paper-Based Analytical Device for Histidine Determination
Applied Biochemistry and Biotechnology, 2020A 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, 2019AbstractMicrofluidic 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.

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
