Journal ArticleDOI
Rational selection of substrates to improve color intensity and uniformity on microfluidic paper-based analytical devices
TL;DR: In this paper, the effect of paper type on the analytical performance of a series of microfluidic paper-based analytical devices (μPADs) fabricated using a CO2 laser engraver was investigated.
Journal ArticleDOI
Highly sensitive colorimetric detection of glucose and uric acid in biological fluids using chitosan-modified paper microfluidic devices
Ellen Flávia Moreira Gabriel,Paulo T. Garcia,Thiago M. G. Cardoso,Flavio Marques Lopes,Felipe T. Martins,Wendell K. T. Coltro +5 more
TL;DR: The modification of microfluidic paper-based analytical devices with chitosan is described to improve the analytical performance of colorimetric measurements associated with enzymatic bioassays and can be a powerful alternative tool for non-invasive glucose analysis.
Journal ArticleDOI
Modification of microfluidic paper-based devices with silica nanoparticles
Elizabeth Evans,Ellen Flávia Moreira Gabriel,Ellen Flávia Moreira Gabriel,Tomás Enrique Benavidez,Wendell K. T. Coltro,Carlos D. Garcia +5 more
TL;DR: The potential of silica nanoparticles to avoid the washing away effect and improve the color uniformity and intensity in colorimetric bioassays performed on μPADs is demonstrated.
Rational selection of substrates to improve color intensity and uniformity on microfluidic paper-based analytical devices
TL;DR: The type of paper and the volume of reagents dispensed in each detection zone can determine the color intensity and uniformity of microfluidic paper-based analytical devices fabricated using a CO2 laser engraver.
Journal ArticleDOI
Paper-Based Colorimetric Biosensor for Tear Glucose Measurements
TL;DR: In this article, a paper-based colorimetric biosensor for measuring glucose concentration levels in human tear samples was presented, which exhibited a linear behavior for the glucose concentration range between 0.1 and 1.0 mM and achieved analytical sensitivity and limit of detection were 84 AU/mM and 50 µM, respectively.
