Simple and covalent fabrication of a paper device and its application in sensitive chemiluminescence immunoassay.
In this paper, chemiluminescence immunoassay (CLIA) was introduced into the recently proposed microfluidic paper-based analytical devices (μPADs) through covalent fabrication strategy for the first time. This novel paper-based CLIA, with high-throughput, rapid, stable and reusable CL response to trace amounts of analyte in real biological samples, combines the simplicity and low-cost of the μPA...
متن کاملA paper based microfluidic device for easy detection of uric acid using positively charged gold nanoparticles.
A paper based microfluidic device is fabricated that can rapidly detect very low concentrations of uric acid (UA) using 3,5,3',5'-tetramethyl benzidine (TMB), H2O2 and positively charged gold nanoparticles ((+)AuNPs). In the presence of (+)AuNPs, H2O2 reacts with TMB to produce a bluish-green colour which becomes colourless on reaction with UA. This colorimetric method can detect as low as 8.1 ...
متن کاملSensitive monitoring of humic acid in various aquatic environments with acidic cerium chemiluminescence detection.
In this research, a simple, sensitive chemiluminescence (CL) method for the determination of humic acid (HA) in water samples was first developed based on the redox reaction between humic acid and cerium(IV) in the acidic condition. Different with the former redox CL reaction which occurred in alkaline solution, no enhancers were needed and neither precipitation nor a second contamination would...
متن کاملHydroxylamine-O-sulfonic acid as an efficient coreactant for luminol chemiluminescence for selective and sensitive detection.
Hydroxylamine-O-sulfonic acid, a versatile reagent for organic synthesis, has been explored as an effective coreactant for luminol chemiluminescence. Co(2+) can dramatically enhance the chemiluminescence of this system. The sensitive detection of Co(2+), luminol and HOSA, including highly selective Co(2+) detection, is achieved.
متن کاملIs CO adequate to facilitate the formation of Pt3M (M = Fe, Ni and Co) nanocubes?
We explore the possibility of preparation of Pt3M (M = Fe, Ni and Co) nanocubes using carbon monoxide as an alternative protocol under different experimental conditions. The results suggest that the sole carbon monoxide flow at ambient pressure can enable the formation of binary Pt-M nanocrystals, but it is inadequate to facilitate the formation of Pt3M nanocubes in the given system under speci...
