We developed a selective and sensitive hyphenated system employing microfluidic-based vapor generation (VG) in conjunction with high-performance liquid chromatography (HPLC) separation inductively coupled plasma-mass spectrometry (ICPMS) detection for the determination of trace inorganic selenium (Se) species. The VG exploited poly(methyl methacrylate) (PMMA) substrates high optical quality to fabricate photocatalyst-assisted reduction device (microfluidic-based PCARD). Moreover, reduce...
To selectively and sensitively determine the trace inorganic As species, As(III) As(V), we developed a nanocomposite-coated microfluidic-based photocatalyst-assisted reduction device (PCARD) as vapor generation (VG) to couple high-performance liquid chromatography (HPLC) separation inductively coupled plasma-mass spectrometry (ICPMS) detection. Au nanoparticles were deposited on TiO2 strengthen conversion efficiency of nanocomposite photocatalytic reduction. The sensitivity for was...
We employed a polymeric material, poly(methyl methacrylate) (PMMA), for fabricating microdevice and then implanted the chlorine (Cl)-containing solid-phase extraction (SPE) functionality into PMMA chip to develop an innovative on-chip dipole-assisted SPE technique. Instead of ion-ion interactions utilized in techniques, dipole-ion between highly electronegative C-Cl moieties channel interior positively charged metal ions were facilitate procedures. Furthermore, avoid labor-intensive manual...
Traditional Chinese herbal medicine has long enjoyed the reputation of world's most advanced system natural medicine. Pinellia ternata is one commonly used herbs in traditional medical science. In this study, five representative ingredients guanosine, methionine, glycine, 3,4-dihydroxybenzaldehyde, and homogentisic acid, were assayed using simple derivatization procedures. Under optimized experimental condition, analytes rapidly separated detected microchip electrophoresis, affording...
Mercury (Hg) is a toxic element impacting on biological systems and ecosystems. Because the toxicity of Hg species highly dependent concentration levels chemical forms, sensitive identification forms for Hg, i.e., speciation, major significance in providing meaningful information about source exposure. In this study, microfluidic-based device made high clarity poly(methyl methacrylate) (PMMA) was fabricated. Then titanium dioxide nanoparticles (nano-TiO2) were attached to treated channel...
Flexible electrochemical supercapacitors (FESCs) are emerging as innovative energy storage systems, characterized by their stable performance, long cycle life, and portability/foldability. Crucial components of FESCs, such electrodes efficient electrolytes, have become the focus extensive research. Herein, we examine deep eutectic solvent (DES)–based polymer gel systems for cost-effective accessibility, simple synthesis, excellent biocompatibility, exceptional thermal stability. We used a...
Abstract Century eggs (also known as pídàn) are a widely used preserved food product in Taiwanese cuisine. Due to their peculiar appearance, pungent odor, and unusual texture, several consumers have raised concerns. Actually, some metallic additives employed control the quality of gelation protein during production century eggs. Therefore, method involving microwave plasma‐atomic emission spectrometer microwave‐assisted digestion was proposed this study. In addition, clarify distribution...
Mercury (Hg) is a toxic element which impacts on biological systems and ecosystems. Because the toxicity of Hg species highly dependent their concentration levels chemical forms, sensitive identification forms Hg—i.e., speciation—is major significance in providing meaningful information about sources exposure. In this study, microfluidic-based device made high-clarity poly(methyl methacrylate) (PMMA) was fabricated. Then, titanium dioxide nanoparticles (nano-TiO2s) were attached to treated...
Abstract Background In this study, a vinylene‐linked covalent organic framework (V‐COF‐1) was integrated with multi‐walled carbon nanotubes (MWCNTs) to create modified electrode (V‐COF‐1/MWCNTs/SPCE) for electrochemical sensing applications. Objective This research focus investigate the application of simultaneous determination tryptophan (Trp), uric acid (UA), and 8‐hydroxy‐2'‐deoxyguanosine (8‐OHdG) in human urine samples mechanism between V‐COF‐1 analytes (Trp, UA, 8‐OHdG) by studying...
