  • Publication number: 20250035581
    Abstract: A biosensor includes a multiplexed array of electrolyte-gated functionalized field effect transistors (FET). Walls fluidically separate each of the FETs from one another provide wells corresponding to each channel of the FETS. A perimeter wall on the upper surface of the multiplex array surrounding the separating walls and traversing the surface of all FETS in the multiplexed array. The perimeter forms a fluidically tight well traversing multiple ones of the FETs. Each of the FETs includes monolayer of a two dimensional material, such as graphene, as a conducting channel, wherein each conducting channel functionalized according to a predetermined agent.

  • Patent number: 10593762
    Abstract: Transferring graphene pieces onto a substrate, by the following steps: a) selecting a substrate comprising a plurality of placeholders for the graphene pieces; b) disposing and aligning the substrate on a substrate holder in a chamber; c) selecting a transfer layer having openings as placeholders for the graphene pieces; d) disposing and aligning the transfer layer on the substrate holder over the substrate so that the openings of the transfer layer are aligned over the placeholders on the substrate; e) adding liquid to the chamber to above the transfer layer, and raising the transfer layer on the liquid column; f) introducing graphene pieces onto the liquid film in the openings of the transfer layer; and g) reducing the distance between the substrate and the graphene pieces until the graphene pieces are disposed on the placeholders of the substrate. A substrate and a device for carrying out the method.

  • Patent number: 10526309
    Abstract: This invention is in the area of improved therapeutic combinations for and methods of treating selected cancers using selected pyrimidine compounds having pan-TAM or Mer/Axl dual receptor tyrosine kinase inhibitory activity in combination with immune checkpoint inhibitors. In one aspect, an improved treatment for select cancers is disclosed using selected pyrimidine compounds described herein in combination with an immune checkpoint inhibitor, for example, a cytotoxic T-lymphocyte-associated protein 4 (CTLA4) inhibitor, a programmed cell death protein 1 (PD1) inhibitor, or a programmed death-ligand 1 (PDL-1) inhibitor, or combination thereof.
