Lubricant-infused surface biosensing interface, methods of making and uses thereof
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.
Producing silanized bio-species and one step rapid top down selective surface immobilization
The present application discloses biofunctional surfaces that have self-assembled monolayers of fluorine groups with “built-in” functional groups promote targeted cell and biomolecule binding to the surface while reducing non-specific binding. Further, this application also relates to methods for preparing functional biomolecules, viruses and cells that can be covalently immobilized to prepare biofunctional surfaces.
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.
Embodiments described herein related to photocatalytically active coatings having improved photocatalytic activity. Embodiments described herein also relate generally to methods for producing graphene-oxide/TiO2 materials and new applications based on the improved photoactivity of the materials. For example, the graphene-oxide/TiO2 can be used in enhanced self-cleaning coatings for surfaces including cement, metal, glass, and wood. Embodiments described herein also relate generally to methods of producing functionalized graphene oxide-TiO2 materials and methods of coatings by surface modification of a substrate and functionalization of the functionalized graphene oxide-TiO2, the functionalized composite being coated onto the target surface after proper surface treatment.
Articles, methods of making, and uses for modifying Surfaces for simultaneously providing repellency and selective binding of desired moieties are disclosed. The repellant Surfaces comprise a substrate and a lubricating layer immobilized over the Substrate Surface having a lubricating liquid having an affinity with the substrate. The substrate and the lubricating liquid are attracted to each other together by non-covalent attractive forces. The repellent surface further includes a binding group extending over the surface of the lubricating layer and the binding group has an affinity with a target moiety. The lubricating layer and the substrate form a slippery or repellent Surface configured and arranged for contact with a material that is immiscible with the lubricating liquid and the immiscible material contains the target moiety.
A technique for separating components of a microfluid, comprises a self-intersecting micro or nano-fluidic channel defining a cyclic path for circulating the fluid over a receiving surface of a fluid component separating member; and equipment for applying coordinated pressure to the channel at a plurality of pressure control areas along the cyclic path to circulate the fluid over the receiving surface, applying a pressure to encourage a desired transmission through the separating member, and a circulating pressure to remove surface obstructions on the separating member. The equipment preferably defines a peristaltic pump. Turbulent microfluidic flow appears to be produced.
