Abstract: Quinolines, polyquinolines, polybenzoquinolines, molecular segments of fullerenes and graphene nanoribbons, and graphene nanoribbons and processes for producing such materials are provided. The processes utilize a form of an aza-Diels-Alder (Povarov) reaction to first form quinolines and/or polyquinolines. In some such embodiments polyquinolines thus produced are used to form graphene nanoribbon precursors, and molecular segments and graphene nanoribbons. In many such embodiments the graphene nanoribbone precursors are formed from polybenzoquinolines.

Abstract: An imaging flow cytometry apparatus and method which allows registering multiple locations across a cell, and/or across multiple flow channels, in parallel using radio-frequency-tagged emission (FIRE) coupled with a parallel optical detection scheme toward increasing analysis throughput. An optical source is modulated by multiple RF frequencies to produce an optical interrogation beam having a spatially distributed beat frequency. This beam is directed to one or more focused streams of cells whose responsive fluorescence, in different frequencies, is registered in parallel by an optical detector.

Abstract: Electrochemical sensors have great promise for point-of-care and in vivo measurement of medically relevant molecules. However, the need for calibrating individual sensors limits the practical applicability of these sensing platforms. The invention provides a novel method of operating electrochemical sensors which obviates the need to calibrate individual sensors against a sample of known concentration. The invention exploits the frequency dependence of electrochemical output signals and the dependence of output signals on the inherent electron transfer kinetics of a selected sensor design. By use of signals generated at a nonresponsive frequency, a normalizing output value is generated that accounts for sensor-to-sensor variation and which enables an accurate calculation of target concentration. The scope of the invention also includes pre-calibrated sensors that may be utilized without calibration steps.

Abstract: A fluorescence microscopy method includes a trained deep neural network. At least one 2D fluorescence microscopy image of a sample is input to the trained deep neural network, wherein the input image(s) is appended with a digital propagation matrix (DPM) that represents, pixel-by-pixel, an axial distance of a user-defined or automatically generated surface within the sample from a plane of the input image. The trained deep neural network outputs fluorescence output image(s) of the sample that is digitally propagated or refocused to the user-defined surface or automatically generated. The method and system cross-connects different imaging modalities, permitting 3D propagation of wide-field fluorescence image(s) to match confocal microscopy images at different sample planes. The method may be used to output a time sequence of images (e.g., time-lapse video) of a 2D or 3D surface within a sample.

Abstract: Disclosed herein are systems and methods for associating metabolites with genes. In some embodiments, after potential metabolites are identified based on spectroscopy data of the content of an organism, possible reactions capable of producing the potential metabolites are determined. The possible reactions are compared to gene sequences in a database, and an association score for the likelihood that a gene sequence is related to the potential metabolites is calculated.

Abstract: According to certain general aspects, the present embodiments relate generally to a device that mobilizes the lens material inside the capsular bag. Mobilized lens material is easier to visualize than lens material lingering at the lens equator of the eye, or other areas in the capsular bag that are difficult to visualize, making the mobilized lens material easier to retrieve from the capsular bag. Mobilizing the lens material reduces the possibility that the person receiving the cataract surgery will develop secondary cataracts or infections due to lens material left inside the capsular bag.
