摘要
A technique for a nanodevice is provided. A reservoir is separated into two parts by a membrane. A nanopore is formed through the membrane, and the nanopore connects the two parts of the reservoir. The nanopore and the two parts of the reservoir are filled with ionic buffer. The membrane includes a graphene layer or a graphene oxide layer. The nanopore could be oxidized to graphene oxide at an inner surface. The graphene or graphene oxide in the nanopore is coated with an organic layer configured to interact with biomolecules in a different way in order to differentiate the biomolecules. The organic layer enhances resolution and motion control of the biomolecules. A time trace of ionic current is monitored to identify the biomolecules based on a respective interaction of the biomolecules with the organic layer.
