  • Patent number: 12181460
    Abstract: A nanosensing device is disclosed for high throughput nucleic acid sequencing or sensing. The device is a silicon chip, having a silicon nitride top layer, an opening through the chip, a hole in the top layer, and a graphene sheet over the top layer and hole. A graphene layer with a p-type crinkle ruga is placed over the hole, and one of more nanopores in the graphene layer may be provided over the hole. A nucleic acid strand transported to the chip may be translocated through a nanopore and the hole by microfluidic forces. An electrical potential across the nanopores can be measured with a patch clamp amplifier to make nucleobase assignments and sequence the DNA. Alternatively, there are no nanopores and the interaction with the crinkle ruga is used to sense the presence of a nucleic acid polymer.
