Abstract
Official abstract text for this publication.
A microfluidic device for manipulating particles can include a substrate and one or more obstacles, each obstacle comprising a plurality of aligned nanostructures including a plurality of nanoparticles or a plurality of polymer layers, or a combination thereof. The obstacle on a substrate can be forests with intra-carbon nanotube spacing ranging between 5-100 nm for isolation of particles such as very small viruses and proteins.
First claim
Opening claim text (preview).
What is claimed is: 1. A fluidic device for manipulating particles comprising: a substrate that defines a fluid path; and one or more obstacles, each obstacle comprising a plurality of aligned nanostructures, wherein the nanostructures are coated with one or more layers of a plurality of nanoparticles and a plurality of polymer layers, wherein nanostructures form an outer surface of an obstacle in the fluid path; wherein the one or more obstacles are fixedly arranged within the fluid path such that some expected paths within the fluid path pass around the outer surface of an obstacle and some expected paths within the fluid path pass through the outer surface of an obstacle and into a network of spaces within the obstacle between the nanostructures. 2. The fluidic device of claim 1 , wherein the nanostructures include a plurality of nanoparticles. 3. The fluidic device of claim 1 , wherein the nanostructures include a plurality of polymer layers. 4. The fluidic device of claim 1 , wherein a distance between adjacent nanostructures is less than 100 nm. 5. The fluidic device of claim 1 , wherein a distance between adjacent nanostructures is less than 10 nm. 6. The fluidic device of claim 1 , wherein the nanostructure is a carbon nanotube.
