Colloidal gold is a kind of nanoparticles of gold which is suspended in a fluid (water, usually) to form a sol. Except for its important roles in the material sciences or other related areas, col...
Broad Detection Range To Fight Against Hook Effect
The hook effect or the prozone effect is a kind of interference induced by high concentrations of the analytes in sandwich immunoassays. When the concentration of the analyte is very hi...
Enzyme-Based Enhancement Of The Signal
Lateral flow immunoassay strips are always used in point-of-care and on-field detection or other situations in which a convenient and non-instrument method is always required. However, without in...
A Naked-Eye Semi-Quantitative LFI System
Lateral flow colloidal gold-based lateral flow immunoassays is a convenient, sensitive and low-cost test method. However, electronic devices are needed for accurate quantification of the res...
Magnetic Particles Magnify The Sensitivity
CDIA test is always dedicated to reduce the limits of detection as much as possible to reach a ultrasensitive method. Here, we will introduce the magnetic particles-based system to raise the sens...
Combine Gold and Silver to Get a Shining Result
Sensitivity, specificity and difficulty of operation are the main 3 factors that are important for the development and choosing lateral flow immunoassays (LFIA) strips. It is hoped that we can get a g...
An introduction to the DNA Dendrimer
DNA is widely used in different formats of detection methods. Scientists have developed a new design to take advantage of the characteristics of DNA, that is, the DNA dendrimer. Scientists have develo...
