The factors that influence the colorimetric gene detection of gold label silver stain and improve the detection signals were studied. The influence of amino DNA probes and thiol DNA modified gold nanoparticles was inv...
The phosphorous amide approach is of the highest coupling efficiency among the DNA in situ synthesis approaches at present. The strict anhydrous condition is required in the process of DNA in situ synthesis, and the D...
A sensitive method is described for the determination of trace antimony based on the antimony-bromopyrogallol red (BPR) adsorption at a carbon paste electrode (CPE). Three steps were involved in the overall analysis: ...
Microporous polyamide-6 membranes were hydrolyzed in 0.01 mol/L NaOH/CH 3OH medium by refluxing for about 36 h. By investigating the UV spectra, the hydrolyzing conditions were optimized. A pH value of 12 and reaction...
