Description

Many ground breaking studies involving the use of graphene based nanopores for DNA

analysis/sequencing have been reported till date. Most of the existing procedures

involve physical transfer of graphene material from its production source to a

freestanding membrane, rendering potential contaminations and mechanical defects.

Other key limitations associated with existing graphene membranes/procedures are

challenging material design, compromised stability, reduced robustness, and

complicated procedure for fabrication of nanopores. This invention discloses a novel

process for production of transfer-free, freestanding graphene membranes,

overcoming most prior art limitations and/or unmet needs. The potential

uses/applications of such graphene membranes are further disclosed.

 

Value Proposition

The graphene membranes:

• Are in-situ fabricated

• Are highly cost effective

• Are extremely thin and associated with a higher resolution

• Are robust and stable as compared to conventional membranes

• Have remarkable mechanical, electrical and optical properties

• Are produced in fewer steps and lesser time as compared to conventional membranes

• Are capable of surviving large transmembrane pressures as compared to existing

membranes

• Would be commercially useful for the following applications:

o Water Desalination

o Production of graphene based solid state gas sensors

o TEM imaging

o DNA and protein sequencing

o Ultrasensitive DNA mapping
