Hollow & Porous Silica Nanoparticles of Various Shapes - Rapid, Scalable, and Simple Production
- Technology Benefits
- ΓÇ£Soft-TemplateΓÇØ synthesis ΓÇö soft template forms consistent size and shape within a batch, but is easily removable to reduce manufacturing complexity and particle breakage.Rapid, simple, and scalable production and removal of the soft-template core.Alternative shapes can be utilized to adjust physical behavior and packing density of the particles.Store as a dry powder or suspended in water at room temp.
- Technology Application
- Incorporate a chemical or ingredient into the hollow core that gradually diffuses into surroundings, such as:Insect traps in which the particles release pheromonesDelivery of volatile catalyst over time from within a reactorControlled release of air fresheners and perfumesDrug or active ingredient delivery with extended releaseAbsorb chemicals from the environment or other setting to detect and / or quantify chemicals in a particular setting or location.
- Detailed Technology Description
- Hollow nanomaterials are produced by sequentially combining polyvinylpyrrolidone and alcohol, then water, sodium citrate, a silicon containing compound, and a catalyst. Create the shapes using different alcohols, e.g., propanol for tadpole shape, ethanol for spheres, and pentanol for nanowires.
- *Abstract
-
The University of North Dakota has developed a rapid and scalable method for producing hollow Silica nanoparticles with a variety of highly reproducible shapes. The nanoparticles are porous, so certain materials may be taken in or released over time.
