Patent number: 10566077Abstract: The disclosure relates to a re-writable DNA-based digital storage system with a random access feature. An example embodiment includes selecting address representations of m nucleotide sequences of n bases each. Each of the address representations of m nucleotide sequences (i) consists of approximately 50% guanine and cytosine content and (ii) is self-uncorrelated. The address representations are mutually uncorrelated with one another. All of the address representations end with a particular base. The embodiment also includes selecting, for a particular address representation from the address representations of the m nucleotide sequences, a corresponding data representation of a nucleotide sequence of L bases. The embodiment further includes concatenating the particular address representation with the data representation to form a representation of a target nucleotide sequence of n+L bases. In addition, the embodiment includes synthesizing the target nucleotide sequence.Type: GrantFiled: November 18, 2016Date of Patent: February 18, 2020Inventors: Olgica Milenkovic, S. M.

Publication number: 20200035331Abstract: The disclosure relates to a re-writable DNA-based digital storage system with a random access feature. An example embodiment includes reading a physical nucleotide sequence of 2n+L bases to form a digital representation of the physical nucleotide sequence; dividing the digital representation of the physical nucleotide sequence into an address representation of n bases, followed by a data representation of L bases, followed by a further address representation of n bases; decoding the data representation into an integer value less than 3L that is a sum of a first addend and a second addend, wherein the data representation includes a first subsequence of bases encoding the first addend followed by a second subsequence of bases encoding the second addend; and storing, in a computer memory, the integer value.Type: ApplicationFiled: October 15, 2019Publication date: January 30, 2020Inventors: Olgica Milenkovic, S.M.

Patent number: 9786857Abstract: A field effect transistor photodetector that can operate in room temperature includes a source electrode, a drain electrode, a channel to allow an electric current to flow between the drain and source electrodes, and a gate electrode to receive a bias voltage for controlling the current in the channel. The photodetector includes a light-absorbing material that absorbs light and traps electric charges. The light-absorbing material is configured to generate one or more charges upon absorbing light having a wavelength within a specified range and to hold the one or more charges. The one or more charges held in the light-absorbing material reduces the current flowing through the channel.Type: GrantFiled: April 5, 2016Date of Patent: October 10, 2017Assignee: NUtech VenturesInventors: Jinsong Huang, Yongbo Yuan

Publication number: 20150123105Abstract: Various aspects of the instant disclosure are directed to methods and to apparatuses involving spin-coating and spin-coated materials. As may be implemented in connection with one or more embodiments, a solution having objects dispersed therein is applied to a substrate and the substrate is spun about an axis that is off-center relative to a center of the substrate. The objects are thus aligned along a predominantly unidirectional orientation. The solution is solidified with the objects aligned to one another along the predominantly unidirectional orientation.Type: ApplicationFiled: November 3, 2014Publication date: May 7, 2015Inventors: Zhenan Bao, Gaurav Giri, Yongbo Yuan, Jinsong Huang
