A Label-free Bio-sensor Using the Change of Liquid Crystal Arrays and Imaging

摘要

The present invention comprises (a) a substrate (substrate); And (b) a functional (functional) compound-comprising doped (doped) LCD (liquid crystal) of the functional compound is chemically modified by the enzyme and the functional compound or metabolite (metabolite) of the detection target microorganism wherein the liquid crystal orientation is by chemical modification of (orientation) is changed and optical appearance (optical appearance) characterized in that the liquid crystal is changed microorganism detection-based relates to a biosensor. The biosensor of the present invention may be functional (functional) compound is visually observed in real-time the presence or absence of a particular microorganism or enzyme in a sample by using a doped (doped) crystal. According to the present invention, can be observed with high sensitivity and high directivity (orientational) at the interface with the optical change due to the reaction occurring chemical / biochemical reaction of only the image of the liquid crystal to know quickly and easily detected in a sample or not. ;
