The streptavidin-biotin affinity was utilised to demonstrate the potential of the birefringence assay platform, using free biotin as the model analyte, biotinylated lipase and streptavidin-coated magnetic beads in the competitive format. A semi-quantitative assay with a detection limit of 5 μg mL-1 to free biotin as the model analyte was achieved in the visual birefringence mode. This study demonstrated a proof-of-concept lyotropic assay platform with birefringence as the visual signal output that could be deployed as an electronics-
