Journal ArticleDOI
One-step polymer screen-printing for microfluidic paper-based analytical device (μPAD) fabrication
Yupaporn Sameenoi,Piyaporn Na Nongkai,Souksanh Nouanthavong,Charles S. Henry,Duangjai Nacapricha +4 more
TL;DR: A simple, low-cost, one-step fabrication method for microfluidic paper-based analytical devices (μPAD) using only polystyrene and a patterned screen is reported, verifying that the polymer screen-printing method can be used as an alternative method for μPAD fabrication.
Journal ArticleDOI
A novel continuous-flow sequential extraction procedure for metal speciation in solids.
TL;DR: A three-step sequential extraction scheme was used to evaluate the novel continuous-flow extraction system by analyzing calcium (Ca), iron (Fe), manganese (Mn), copper (Cu), and zinc (Zn) in a soil certified reference material.
Journal ArticleDOI
Pesticide analysis using nanoceria-coated paper-based devices as a detection platform
Souksanh Nouanthavong,Souksanh Nouanthavong,Duangjai Nacapricha,Charles S. Henry,Yupaporn Sameenoi +4 more
TL;DR: The developed method was successfully applied to detect methyl-paraoxon in spiked vegetables and a dried seafood product, obtaining ∼95% recovery values for both sample types, indicating that the developed method gives accurate results and is suitable for OP analysis in real samples.
Journal ArticleDOI
Thin-film organic photodiodes for integrated on-chip chemiluminescence detection – application to antioxidant capacity screening
Xuhua Wang,Maliwan Amatatongchai,Maliwan Amatatongchai,Duangjai Nacapricha,Oliver Hofmann,John C. de Mello,Donal D. C. Bradley,Andrew J. de Mello +7 more
TL;DR: In this paper, a solution processed thin-film organic photodiodes (OPDs) can be used as compact and sensitive integrated detectors for antioxidant capacity screening, and the OPDs were fabricated with blends of regioregular poly(3-hexylthiophene) (P3HT) and (6,6)-phenyl C61 butyric-acid methyl-ester (PCBM).
Journal ArticleDOI
Highly sensitive and selective electrochemical paper-based device using a graphite screen-printed electrode modified with molecularly imprinted polymers coated Fe3O4@Au@SiO2 for serotonin determination.
