SYSTEM AND METHOD FOR DETECTING PATHOGENS ON TREATED AND UNTREATED SUBSTRATES USING LIQUID CRYSTAL CHROMONIC AZO DYE

摘要

Chromonic azo dyes are particular types of chromonic molecules that are alignable homeotropically (aggregated molecules stacked 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.
