Patent number: 10837057Abstract: Under one aspect, a device is provided for use in luminescent imaging. The device can include a photonic superlattice including a first material, the first material having a first refractive index. The first material can include first and second major surfaces and first and second pluralities of features defined through at least one of the first and second major surfaces, the features of the first plurality differing in at least one characteristic from the features of the second plurality. The photonic superlattice can support propagation of a first wavelength and a second wavelength approximately at a first angle out of the photonic superlattice, the first and second wavelengths being separated from one another by a first non-propagating wavelength that does not selectively propagate at the first angle out of the photonic superlattice.Type: GrantFiled: October 17, 2019Date of Patent: November 17, 2020Assignee: Illumina, Inc.Inventors: Dietrich Dehlinger, Cheng Frank Zhong, Juraj Topolancik

Publication number: 20200158687Abstract: Embodiments of the present technology may allow for the analysis of molecules by tunneling recognition at a tunneling junction. A tunneling junction of the present technology can include an insulating layer between two electrodes. A voltage may be applied to the electrodes. When a molecule makes contact with both electrodes, the molecule allows current to tunnel through the molecule. The characteristics of the current may aid in identifying a portion of the molecule, for example, a particular nucleotide or base present in a nucleic acid molecule. Methods and systems for analysis of molecules are described.Type: ApplicationFiled: January 23, 2020Publication date: May 21, 2020Inventors: Yann ASTIER, Juraj TOPOLANCIK

Publication number: 20190390267Abstract: Molecules may be analyzed (e.g., sequencing of nucleic acid molecules) by tunneling recognition at a tunneling junction. Embodiments of the present invention may allow detecting individual nucleotides and the sequencing of a nucleic acid molecule using a tunneling junction. By labeling a specific nucleotide with a moiety, tunneling junctions may generate a signal with a suitable signal-to-noise ratio. The tunneling recognition uses a tunneling current that is mostly through the moiety rather than mostly through the nucleotide or a portion of the molecule of interest. Because a single nucleotide can be detected with a signal with a suitable signal-to-noise ratio resulting from the tunneling current passing through the moiety, embodiments of the present invention may allow for fast detection of nucleotides using a tunneling current.Type: ApplicationFiled: June 19, 2019Publication date: December 26, 2019Inventors: Yann ASTIER, Juraj TOPOLANCIK, Hannes KUCHELMEISTER, Frank BERGMANN, Dieter HEINDL, Nikolaus Klaus-Peter STEINGELE

Publication number: 20190310241Abstract: Embodiments of the present technology may allow for improved and more reliable tunneling junctions and methods of fabricating the tunneling junctions. Electrical shorting issues may be reduced by depositing electrodes without a sharp sidewall and corner but instead with a sloping or curved sidewall. Layers deposited on top of the electrode layer may then be able to adequately cover the underlying electrode layer and therefore reduce or prevent shorting. Additionally, two insulating materials may be used as the dielectric layer may reduce the possibility of incomplete coverage and the possibility of flaking. Furthermore, the electrodes may be tapered from the contact area to the junction area to provide a thin electrode where the hole is to be patterned, while the thicker contact area reduces sheet resistance. The electrode may also be patterned to be wider at the contact area and narrower at the junction area.Type: ApplicationFiled: April 5, 2019Publication date: October 10, 2019Inventors: Juraj TOPOLANCIK, Zsolt MAJZIK, Flint MITCHELL

Publication number: 20190170904Abstract: A device for luminescent imaging includes an array of imaging pixels, a photonic structure over the array of imaging pixels, and an array of features over the photonic structure. A first feature of the array of features is over a first pixel of the array of imaging pixels, and a second feature of the array of features is over the first pixel and spatially displaced from the first feature. A first luminophore is within or over the first feature, and a second luminophore is within or over the second feature. The device includes a radiation source to generate first photons having a first characteristic at a first time, and generate second photons having a second characteristic at a second time. The first pixel selectively receives luminescence emitted by the first and second luminophores responsive to the first photons at the first time and second photons at the second time, respectively.Type: ApplicationFiled: April 21, 2017Publication date: June 6, 2019Inventors: Juraj TOPOLANCIK, Cheng Frank ZHONG
