Abstract: This application relates to omniphobic materials which are physically and chemically modified at their surface to create hierarchically structured materials with both nanoscale and microscale structures that provide the omniphobic properties. Methods of making such omniphobic surfaces with hierarchical structures and uses thereof, including as flexible films that repel contaminants are also disclosed in the application.

CPC classification number: G01N33/54353

Abstract: This application relates to a method for fabricating a biofunctionalized surface on a substrate, wherein the substrate comprises hydroxyl groups on the surface to be biofunctionalized, the method comprising: covalently attaching organosilane groups to less than all of the hydroxyl groups on the surface of the substrate; covalently attaching one or more biospecies to the surface of the substrate; and applying a lubricant to the substrate, wherein the biospecies comprises a biorecognition element that detects a target analyte in a sample. A biofunctionalized surface made therefrom and use thereof, such as for biosensing applications, are also disclosed.

Abstract: The present application relates to lubricant-infused molds such as omniphobic lubricant-infused molds and uses thereof, for example, in processes for fabricating molded objects such as microfluidics devices. Such processes can comprise coating a mold with a layer comprising a lubricant-tethering group to obtain a tether-coated mold, depositing a lubricant on the tether-coated mold to obtain a lubricant-infused mold (LIM), depositing a molded object precursor into the LIM and solidifying to obtain the molded object, and removing the molded object from the LIM.
