Patent number: 10895617Abstract: A method for probing the properties of nanoscale materials, such as 2D materials or proteins, via nanometer-scale nuclear quadrupole resonance (NQR) spectroscopy using individual atom-like impurities in diamond. Coherent manipulation of shallow nitrogen-vacancy (NV) color centers enables the probing of the NQR spectrum of nanoscale ensembles of nuclear spins. Measuring the NQR spectrum at different magnetic field orientations and magnitudes and fitting to a theoretical model allows for the extraction of atomic structural properties of the material with nanoscale resolution.Type: GrantFiled: May 24, 2017Date of Patent: January 19, 2021Assignee: President and Fellows of Harvard CollegeInventors: Igor Lovchinsky, Javier Sanchez, Elana K.

Publication number: 20200347393Abstract: The present invention generally relates to micro- and nanoneedles, e.g., for use in penetrating plant cells, or other cells. In some embodiments, delivery of target biomolecules into cells with protective outer layers (e.g. plant cells or plant pollen), cells in seeds, or cells in tissues may be achieved. These outer layers could be native biological protections (e.g. complex exines for pollens), other types of cells, or general biological materials. In some cases, the needles are attached at an end on a surface. In some cases, pollen or seeds may have substantially thick and tough layers (intine and exine), which may render it more difficult to penetrate such materials, as compared with cell membranes, e.g., in mammalian cells.Type: ApplicationFiled: December 7, 2018Publication date: November 5, 2020Applicant: President and Fellows of Harvard CollegeInventors: Hongkun Park, Xing Liao, Jeffrey T.

Publication number: 20200292482Abstract: Methods and systems for monitoring the activity of electrogenic networks are described. One representative system includes an array of electrode coupled to an analyzer having a stimulator and a receiver. The electrode is placed in contact with an electrogenic cell. The electrodes can be shaped as nanowires, tubes, cavities and/or cones. The analyzer may be configured to operate in a voltage stimulation mode, in which the cells are stimulated via voltages and monitored via current, or in a current stimulation mode, in which the cells are stimulated via currents and monitored via voltages. The analyzers may be arranged as single-stage amplifiers, and may include a feedback loop shared between the stimulation signal path and the sensing signal path. The feedback loop may be arranged to provide overlapping stimulation and sensing of the electrogenic network's cells.Type: ApplicationFiled: October 30, 2018Publication date: September 17, 2020Applicant: President and Fellows of Harvard CollegeInventors: Donhee Ham, Hongkun Park, Keith Krenek, Tianyang Ye, Jeffrey T.
