Nanofluidic devices enabled by 3D direct-write nanolithography
Handling small volumes of liquids in nanofluidic channels is often used in nano- and biotechnology. The applications range from DNA sequencing to sorting, assembling and manipulating nanoparticles, proteins, enzymes or viruses.
Ultra-high resolution holes and channels for single DNA molecules to pass through
Accurate 3D topography of a channel guides of particles in the liquid
Local variations of surface chemistry control binding and assembly of biomolecules
Brownian motors-based nanoparticle sorting device
Nanofluidic ratchets fabricated with single-nanometer accuracy by NanoFrazor patterning. A nanofluidic device with a precisely engineered 3D topography harnesses Brownian motion to separate particles with down to 1nm size difference by guiding them in opposite directions.
