Abstract

The present invention provides liquid crystal (LC)-infused materials and methods for detecting compounds or impurities in liquid samples using such materials. These slippery materials comprise a lubricating liquid, preferably a thermotropic liquid crystal, and a solid substrate able to immobilize or host the lubricating liquid. The portion of the substrate coated by the lubricating fluid forms a slippery surface able to allow droplets of various materials to slide off the slippery surface in a manner dependent on the chemical composition of the droplet, which can be used to detect the presence of analytes, impurities and other molecules within the droplet.
