Journal ArticleDOI
Multilayer Paper-Based Device for Colorimetric and Electrochemical Quantification of Metals
Poomrat Rattanarat,Wijitar Dungchai,David M. Cate,John Volckens,Orawon Chailapakul,Charles S. Henry +5 more
TL;DR: A simple, inexpensive technology with the potential to render toxic metals detection accessible for both the developing and developed world that combines colorimetric and electrochemical microfluidic paper-based analytical devices (mPAD) in a three-dimensional configuration is reported on.
Journal ArticleDOI
An electrochemical sensor based on graphene/polyaniline/polystyrene nanoporous fibers modified electrode for simultaneous determination of lead and cadmium
Nadtinan Promphet,Poomrat Rattanarat,Ratthapol Rangkupan,Orawon Chailapakul,Nadnudda Rodthongkum +4 more
TL;DR: In this article, the development of graphene/polyaniline/polystyrene (G/PANI/PS) nanoporous fiber modified screen-printed carbon electrode (SPCE) using electrospinning fabrication for simultaneous determination of lead (Pb 2+ ) and cadmium (Cd 2+ ), was achieved.
Journal ArticleDOI
Nanoparticle-based electrochemical detection in conventional and miniaturized systems and their bioanalytical applications: a review.
TL;DR: The progress of NP-based electrochemical detection in recent applications, especially in bioanalysis, is reviewed, and the main functions of NPs in conventional and miniaturized systems are summarized.
Journal ArticleDOI
A microfluidic paper-based analytical device for rapid quantification of particulate chromium.
Poomrat Rattanarat,Wijitar Dungchai,David M. Cate,Weena Siangproh,John Volckens,Orawon Chailapakul,Charles S. Henry +6 more
TL;DR: A novel, simple, inexpensive microfluidic paper-based analytical device (μPAD) is reported for measuring total Cr in airborne particulate matter and quantitative agreement was obtained between known Cr levels in the sample and the Cr measured using the μPAD.
Journal ArticleDOI
Sodium dodecyl sulfate-modified electrochemical paper-based analytical device for determination of dopamine levels in biological samples
TL;DR: The ePAD seems suitable as a low cost, easy-to-use, portable device for the selective quantitation of DA in human serum samples.
