Mark Ming-Cheng Cheng has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9630183
    Abstract: An electrowetting device and a method of electrowetting may be provided. An electrode may be provided. The electrode has a graphene layer having a first side and a second side that opposes the first side. The electrode also has a dielectric layer disposed on the first side of the graphene layer. A liquid droplet is disposed on the dielectric layer. A voltage is applied through the droplet and the electrode. A contact angle between the dielectric layer and an edge of the liquid droplet contacting the dielectric layer changes in response to the applied voltage.
    Type: Grant

    Date of Patent: April 25, 2017
    Assignee: WAYNE STATE UNIVERSITY
    Inventors: Mark Ming-Cheng Cheng, Xuebin Tan, Zhixian Zhou
  • Publication number: 20150038378
    Abstract: A graphene biosensor is formed on an electrically insulating substrate with a single-layer graphene sheet arranged between two metallic electrodes. The graphene sheet is in electrical contact with the metallic electrodes. The graphene sheet has perforations creating edges in the graphene sheet. The perforations may be holes on a micrometer scale or in a nanometer scale. The biosensor can be configured as an ISFET. The graphene sheet may comprise affinity probes immobilized on the edges for attaching specific molecules to the graphene sheet. Several graphene sheets may be arranged in a microarray with different affinity probes on different graphene sheets. The sensor may also be arranged on the distal end of a catheter for in situ measurements in a body vessel.
