摘要
Chromonic azo dyes are particular types of chromonic molecules that are alignable homeotropically (aggregated molecules stack perpendicularly to the surface) on different types of substrates, often without the need of any special surface treatment. This feature enables the optimization of a detection device with increased sensitivity based of the alignment distortion created by a biological immune complex.
