Strategic Insights

— 1 min read

LYTEN, INC. has been granted a patent for its innovative biofunctionalized three-dimensional (3D) graphene-based field-effect transistor (FET) sensor technology. This groundbreaking invention, developed by four inventors, has the potential to revolutionize the field of biosensing by providing a highly sensitive and selective detection of analytes. The BioFET sensor features a unique design, including a biofunctionalized 3D graphene layer that can detect changes in electrical properties in response to the presence of an analyte. This technology has far-reaching implications for various applications, including medical diagnostics, environmental monitoring, and food safety.

Key Takeaways:

  • The patented BioFET sensor technology features a 3D graphene-based FET sensor with a biofunctionalized layer that can detect changes in electrical properties in response to the presence of an analyte.
  • The sensor includes a substrate, source and drain regions, an insulating layer, a gate, a well region with an electrolyte solution, and a passivation layer.
  • The 3D graphene layer is biofunctionalized with a molecular recognition element that can alter the electrical properties of the graphene in response to exposure to the analyte.
  • In some aspects, the 3D graphene layer is produced from carbon-containing inks, while in other aspects, it includes a convoluted 3D structure to prevent graphene restacking.
  • The passivation layer is designed to prevent the electrolyte solution from contacting the source and drain regions.
  • This technology has the potential to revolutionize the field of biosensing by providing a highly sensitive and selective detection of analytes.
  • The BioFET sensor can be used in various applications, including medical diagnostics, environmental monitoring, and food safety.
