This invention relates generally to covalently crosslinked colloidal cellulose nanocrystals (xCNC) and methods of preparation and use thereof. The colloidal cellulose nanocrystals (CNCs) are covalently crosslinked in aqueous suspension to generate a network showing tunable physicochemical properties. The xCNC structures are tunable in terms of their physicochemical properties and arrangement within the hydrogel network. The covalent crosslinking of solitary sulfonated (—OSO) CNCs can be accomplished without prior hydroxyl replacement or functionalization.

Crosslinked colloidal cellulose nanocrystals and methods of preparation and use thereof

A process for fabricating a nanochannel system using a combination of microelectromechanical system (MEMS) microfabrication techniques, atomic force microscopy (AFM) nanolithography, and focused ion beam (FIB). The nanochannel system, fabricated on either a glass or silicon substrate, has channel heights and widths on the order of single to tens of nanometers. The channel length is in the micrometer range. The nanochannel system is equipped with embedded micro and nanoscale electrodes, positioned along the length of the nanochannel for electron tunneling based characterization of nanoscale particles in the channel. Anodic bonding is used to cap off the nanochannel with a cover chip.

Method of fabricating a nanochannel system for DNA sequencing and nanoparticle characterization

A method of producing a nanoparticle assembly. The method includes attaching a first DNA molecule to a bead to form a first DNA-bead complex; and combining a nanoparticle with the first DNA-bead complex to form a nanoparticle-DNA-bead complex having one DNA molecule attached to the nanoparticle.
