Abstract
A system for the detection of ligands comprising at least one receptor and an amplification mechanism coupled to the receptor wherein an amplified signal is produced as a result of receptor binding a ligand. Examples of suitable amplification mechanisms include antibody-embedded liquid crystalline materials; use of alpha-2-macroglobulin to encage an enzyme, whereby the enzyme is separated from its substrate by an receptor; and a receptor engineered to inhibit the active of site of an enzyme only in the absence of a ligand. Also provided are methods for the automatic detection of ligands.
