Publication number: 20190249243Abstract: To introduce a biomolecule into a nanopore without the need to check the position of the nanopore in a thin film. In addition, displacement stability is ensured and stable acquisition of blocking signals is realized. An immobilization member 107 having a larger size than a thin film 113 with a nanopore 112 is used, and biomolecules are immobilized on the biomolecule immobilization member 107 at a density that allows at least one biomolecule 108 to enter an electric field region around the nanopore when the biomolecule immobilization member 107 has moved close to a nanopore device 101.Type: ApplicationFiled: April 26, 2019Publication date: August 15, 2019Inventors: Rena AKAHORI, Itaru YANAGI, Kenichi TAKEDA

Publication number: 20190249244Abstract: The present disclosure provides biochips and methods for making biochips. A biochip can comprise a nanopore in a membrane (e.g., lipid bilayer) adjacent or in proximity to an electrode. Methods are described for forming the membrane and insert-ing the nanopore into the membrane. The biochips and methods can be used for nucleic acid (e.g., DNA) sequencing. The present disclosure also describes methods for detecting, sorting, and binning molecules (e.g., proteins) using biochips.Type: ApplicationFiled: April 26, 2019Publication date: August 15, 2019Applicant: GENIA TECHNOLOGIES, INC.Inventors: Randall DAVIS, Roger CHEN

Publication number: 20190249245Abstract: The present invention relates functional ligands to target molecules, particularly to functional nucleic acids and modifications thereof, and to methods for simultaneously generating, for example, numerous different functional biomolecules, particularly to methods for generating numerous different functional nucleic acids against multiple target molecules simultaneously. The present invention further relates to functional ligands which bind with affinity to target molecules, such as lipoarabinomannan (LAM).Type: ApplicationFiled: January 30, 2019Publication date: August 15, 2019Inventors: George W.
