  • Patent number: 9632033
    Abstract: A technique relates to determining a presence of a known nucleic acid sequence of a known molecule in a sample. A sample surface is coated with a select segment of the known molecule. Beads are coated with a first molecule. A targeted nucleic acid sequence is attached to a second molecule that binds to the first molecule, such that the targeted nucleic acid sequence is attached to the beads via first and second molecules. The sample is placed on the sample surface. The sample includes the liquid medium, beads, and targeted nucleic acid sequence being tested. Brownian motion of beads is monitored to determine whether the Brownian motion of the beads is restricted or not restricted. When the Brownian motion of beads is restricted, the presence of the known nucleic acid sequence is in the sample, thus indicating that the targeted nucleic acid sequence is the known nucleic acid sequence.

  • Publication number: 20160281157
    Abstract: A mechanism is provided for sequencing a biopolymer. The biopolymer is traversed from a first medium to a second medium. The biopolymer includes bases. As the biopolymer traverses from the first medium to the second medium, different forces are measured corresponding to each of the bases. The bases are distinguished from one another according to the different measured forces which are measured for each of the bases.

  • Publication number: 20160024567
    Abstract: A technique for electrical detection of a molecule is provided. A fluidic bridge is formed between a nanopipette and a fluid cell, where the molecule is in the nanopipette. A voltage difference is applied between the nanopipette and the fluid cell, where the fluid cell contains an electrolyte solution. Entry of the molecule into the fluidic bridge is determined by detecting a fore pulse. The fluidic bridge between the nanopipette and the fluid cell is broken to form a nanogap. In response to waiting a time interval, the fluidic bridge is reformed between the nanopipette and the fluid cell to close the nanogap. The molecule is determined to exit the nanopipette by detecting an after pulse.
