  • System for detecting a target material in a sample using liquid crystals
    Patent number: 11513117
    Abstract: A system for detecting a target material in a sample. The system includes a sensor, a light source, an image-capturing device, two linear-crossed polarizers including a first polarizer and a second polarizer, and a processing unit. The sensor is configured to place the sample thereon and includes a fabric impregnated with liquid crystals (LCs). The light source is configured to transmit a beam of light through a path passing from the first polarizer, the sensor, and the second polarizer. The image-capturing device is configured to capture an image of a surface of the second polarizer. The image contains a pattern formed by orientations of LCs corresponding to the sample. The processing unit is configured to detect a presence of the target material in the sample by analyzing the captured image.
