Nanopore Sensors
Solid-state nanopores are nanometer-sized openings in 2D or nanometer-thickness inorganic materials. Such nanopores can be used as biological sensors and DNA sequencers. Compared to biological nanopores, which are found in cells, solid-state nanopores offer a greater level of precision for the pore’s functionality. By controlling material and surface chemistry, the biomolecule-nanopore interaction can be tuned for specific purposes, such as enhancing or reducing DNA-surface interaction.

Graphene Membranes
Graphene membranes show promise for next generation filtration and desalination. Due to the ease with which graphene can be functionalized, such membranes offer a broad range of capabilities through chemical tailoring of the specific functional groups attached. We work on synthesizing graphene oxide (GO) and GO-derivatives to make filtration membranes for desalination, pervaporation, and electrodialysis. Such GO and GO-derivative membranes are capable of nearly full-ion rejection while retaining ultra-high water flux.
