  • Using liquid crystals to detect affinity microcontact printed biomolecules
    Patent number: 8133680
    Abstract: The present invention provides methods, devices and kits for detecting a ligand. The methods involve capturing a ligand from a sample with an affinity substrate that includes a receptor for a ligand, transferring captured ligand to a detection surface and detecting the ligand on the detection surface with a liquid crystal. Accordingly, the capture step is decoupled from the detection step.
