Publication number: 20230227892Abstract: The relative abundance of bacterial species in a patient’s microbiome is quantified using DNA nanostructures that fluoresce multiple colors. Immobilizing binders have binding sites with nucleotide sequences complementary to those at a primary site on rRNA subunits of each selected bacterial species. Fluorophore binders have binding sites with nucleotide sequences complementary to those at a secondary site on the rRNA subunits. The fluorophore binders for each bacterial species are attached to nanostructures that fluoresce a particular color for each bacteria. The immobilizing binders are attached to the surface of a microscopy chamber. RNA subunits are extracted from a microbiome sample of the patient and are attached to the corresponding immobilizing binders and fluorophore binders such that the RNA subunits of each bacterial species fluoresce a color unique to the species. DNA nanostructures emitting the same color are counted to determine the relative concentration of the bacterial species in the sample.Type: ApplicationFiled: January 14, 2022Publication date: July 20, 2023Inventors: Johannes Benedikt Woehrstein, Heinrich Ernst Paul Grabmayr

Patent number: 11513076Abstract: The present invention relates to a method and a DNA nanostructure for detecting a target structure. In particular, the present invention relates to a DNA nanostructure, which ensures a preferably linear dependence on the number of marker molecules and the measurement signal regardless of the physical arrangement of a plurality of such DNA nanostructures by virtue of the skilled selection of the shape of the DNA nanostructure and the placement of the marker molecules attached to it. The invention additionally relates to the use of said DNA nanostructures and other nanoreporters, preferably in combination with adapters which bind specifically to target molecules, in a method for quantifying a plurality of target molecules, preferably in a simultaneous manner, using a multiplex method.Type: GrantFiled: June 14, 2017Date of Patent: November 29, 2022Assignee: LUDWIG-MAXIMILIANS-UNIVERSITÄT MÜNCHENInventors: Heinrich Grabmayr, Johannes Benedikt Woehrstein

Patent number: 9897637Abstract: A pre-characterised high frequency signal (14) is provided by means of a non-linear circuit, for example an amplifier circuit (10), fed with a first signal (12) with a component at a first, fundamental, frequency (FO). The amplifier circuit generates an output signal comprising harmonic components (14h1, 14h2, 14h3) having stable and predetermined phase relation relative to each other. Information concerning the phase relation of the harmonic frequency components is provided, for example by means of a data file (16). At least two of the harmonic components are at the tenth or lower harmonic frequencies. The signal strength of such low-order harmonic components may be relative high, thus enabling the provision of a pre-characterised high frequency multi-tone signal from the amplifier circuit with high signal to noise ratio.Type: GrantFiled: October 8, 2013Date of Patent: February 20, 2018Inventors: Johannes Benedikt, Tudor Vyvyan Williams

Publication number: 20120161784Abstract: The present invention relates to a measurement system and method for analysing, and characterising, the behaviour of a high frequency device, commonly referred to in the art as a device under test (or DUT) at relatively high power levels. Such devices may for example need to be analysed when designing devices or designing circuits utilising such devices, for use in high power (large signal) high frequency amplifiers, such as an amplifier for use in a mobile telephone network or other telecommunications-related base-station. The measurement apparatus for measuring the response of an electronic device to a high frequency input signal includes an active load-pull circuit connectable in use to an electronic device to be measured. The active load-pull circuit includes a passive load-pull device.Type: ApplicationFiled: June 4, 2010Publication date: June 28, 2012Applicant: MESURO LIMITEDInventor: Johannes Benedikt

An embodiment of the invention provides a high frequency non-linear measurement system including one or more multiplexer circuits. Each multiplexer circuit comprises a first signal-combining circuit and a second signal-combining circuit. Each signal-combining circuit comprises a pair of directional couplers connected via a pair of signal filters arranged in parallel.Type: ApplicationFiled: December 8, 2009Publication date: January 12, 2012Inventor: Johannes Benedikt

Publication number: 20110025296Abstract: An analyser for measuring the response of an electronic device (DUT 206) to an RF input signal from a signal generator 240a is described. An active load pull circuit 201 is connected to the DUT 206, which receives an output signal from the DUT 206 and then feeds a modified signal back to the DUT 206. The signal is modified by a signal processing circuit 237 in view of input signals x, y to control the magnitude gain and phase change effected by the feedback circuit 237. Thus, positive feedback loops are avoided and better control of the analyser is permitted. A network analyser, or other signal measuring device 242, logs the waveforms (from which s-parameters derived) observed at ports of the DUT 206, thereby allowing the behaviour of the DUT 206 under various load conditions to be analysed.Type: ApplicationFiled: October 18, 2010Publication date: February 3, 2011Applicant: MESURO LIMITEDInventors: Johannes Benedikt, Paul Juan Tasker
