Accurate and interference-free multiplexed quantitative proteomics using mass spectrometry
U.S. Patent 10,145,818 (December 4, 2018)
Martin Helmut Wuhr, Steven P. Gygi, Wilhelm Haas, Graeme Conrad McAlister, Leonid Peshkin, Ramin Rad, and Marc W. Kirschner
Abstract: Embodiments are directed to a method, a computer readable medium encoded with instructions that, when executed, perform a method, and a system for performing mass spectrometry analysis. Molecules of different samples may be labeled with a chemical tag, allowing a multiplexed analysis of multiple samples. The labeled molecules may be fragmented, each fragmented molecule creating at least two separate ions. The relative abundance of each of the heavier ions, which may comprise the original molecule from the sample, may be measured. A relative abundance of the labeled molecules in each of the samples may be determined from the measured relative abundances of the heavier ions.
Band-gap tunable elastic optical multilayer fibers
U.S. Patent 10,146,007 (December 4, 2018)
Joanna Aizenberg, Mathias Kolle, Peter Vukusic, and Robert D. Howe
Abstract: The rolled photonic fibers presents two codependent, technologically exploitable features for light and color manipulation: regularity on the nanoscale that is superposed with microscale cylindrical symmetry, resulting in wavelength selective scattering of light in a wide range of directions. The bio-inspired photonic fibers combine the spectral filtering capabilities and color brilliance of a planar Bragg stack compounded with a large angular scattering range introduced by the microscale curvature, which also decreases the strong directional chromaticity variation usually associated with flat multilayer reflectors. Transparent and elastic synthetic materials equip the multilayer interference fibers with high reflectance that is dynamically tuned by longitudinal mechanical strain. A two-fold elongation of the elastic fibers results in a shift of reflection peak center wavelength of over 200 nm.
Deposition of RFID tags
U.S. Patent 10,149,736 (December 11, 2018)
Michael J. Smith, Frank L. Hammond, III, Robert J. Wood, and Simon G. Talbot
Abstract: In a method for printing an RFID tag on an object, a deposition mask is applied to the surface of an object. With the deposition mask on the surface of the object, RFID materials are deposited on at least one portion of the surface exposed by aperture(s) in the deposition mask. In particular embodiments, RFID tags can be deposited on medical instruments.

Another aspect includes a pharmaceutical composition for altering microbiota that includes a therapeutically effective amount of substantially purified microbiota and a pharmaceutically acceptable carrier. Yet another aspect includes methods for treating a disorder, such as obesity, in a subject in need of such treatment by changing relative abundance of microbiota in a gastrointestinal tract of the subject without or in addition to a surgical procedure.

U.S. Patent 10,151,304 (December 11, 2018)
Samuel M. Felton, Robert J. Wood, Michael T. Tolley, Erik D. Demaine, and Daniela Rus
Abstract: A self-folding machine comprises a laminate including a flexible layer with a first side and a second side; a first rigid layer including at least one gap laminated to the first side of the flexible layer; a second rigid layer including at least one gap laminated to the second side of the flexible layer, wherein the rigid layers are more rigid than the flexible layer; a first contractible layer laminated to the first rigid layer and extending across at least one gap in the first rigid layer; and a second contractible layer laminated to the second rigid layer and extending across at least one gap in the second rigid layer, wherein the first and second contractible layers retract to respectively create folds in the machine across gaps in the first and second rigid layers when activated.
Rapid production of droplets
U.S. Patent 10,151,429 (December 11, 2018)
David A. Weitz and Esther Amstad
Abstract: The present invention generally relates to the production of fluidic droplets. Certain aspects of the invention are generally directed to systems and methods for creating droplets by flowing a fluid from a first channel to a second channel through a plurality of side channels. The fluid exiting the side channels into the second channel may form a plurality of droplets, and in some embodiments, at very high droplet production rates. In addition, in some aspects, double or higher-order multiple emulsions may also be formed. In some embodiments, this may be achieved by forming multiple emulsions through a direct, synchronized production method and/or through the formation of a single emulsion that is collected and re-injected into a second microfluidic device to form double emulsions.
Printed stretchable strain sensor
U.S. Patent 10,151,649 (December 11, 2018)
Jennifer A. Lewis, Joseph T. Muth, Daniel M. Vogt, Ryan L. Truby, Yigit Menguc, David B. Kolesky, and Robert J. Wood
Abstract: A printed stretchable strain sensor comprises a seamless elastomeric body and a strain-sensitive conductive structure embedded in the seamless elastomeric body. The strain-sensitive conductive structure comprises one or more conductive filaments arranged in a continuous pattern. A method of printing a stretchable strain sensor comprises depositing one or more conductive filaments in a predetermined continuous pattern into or onto a support matrix. After the depositing, the support matrix is cured to embed a strain-sensitive conductive structure in a seamless elastomeric body.

Abstract: The invention provides methods for characterizing cellular physiology by incorporating into an electrically excitable cell an optical reporter of, and an optical actuator of, electrical activity. A signal is obtained from the optical reporter in response to a stimulation of the cell. Either or both of the optical reporter and actuator may be based on genetically-encoded rhodopsins incorporated into the cell. The invention provides all optical methods that may be used instead of, or as a complement to, traditional patch clamp technologies and that can provide rapid, accurate, and flexible assays of cellular physiology.
