Disclosed herein, inter alia, are methods for detecting cancer using nanoparticles.

The present invention relates to novel tricarbocyanine-cyclodextrin(s) conjugates useful as markers in the diagnosis of kidney diseases, a diagnostic composition comprising said conjugates, their use and their production.

The present disclosure relates to method of performing an interventional procedure using flexible probes with a compound or a composition comprising the compound, wherein the compound comprises a targeting moiety, wherein the targeting moiety targets a receptor, antigen, or antibody and a fluorescence imaging agent.

The present disclosure relates to compounds that are useful as near-infrared fluorescence probes, wherein the compounds include i) a ligand that binds to the active site of carbonic anhydrase, ii) a dye molecule, and iii) a linker molecule that comprises an amino acid, amide, ureido, or polyethylene glycol derivative thereof. The disclosure further describes methods and compositions for making and using the compounds, methods incorporating the compounds, and kits incorporating the compounds.

A method for using bodily fluids in determining the cell-specific potency of drugs is provided. A composition comprising a plurality of types of carriers, wherein each carrier comprises a single-cell lethal amount of a therapeutic agent and a unique barcode identifying that agent and wherein the composition comprises equal numbers of each carrier type, equal concentrations of the agent and equal concentrations of each barcode is also provided. Further, methods useful for studying the therapeutic profile of one or more drugs within a cell microenvironment, including but not limited to a tumor, are provided.

The invention encompasses a rapid and safe preparation method of sperm nuclei, improved sperm nuclei and a method of using the improved sperm nuclei to calibrate a flow cytometer with higher accuracy.

A fluorescent solution is disclosed for use in a hydraulic or diesel fluid to facilitate detection of injection of the hydraulic of diesel fluid into a human. The fluorescent solution includes a fluorescent dye and a stabilizing agent. The stabilizing agent may be a surfactant. A hydraulic fluid mixture is also disclosed which includes a fluorescent solution and a hydraulic fluid.

The control unit includes, as a mechanical configuration, an image processing unit and a recording control unit. The image processing unit includes a combining unit that combines the fluorescence image acquired by the illuminating/photographing unit and the visible light image, a condition designation unit that designates an analysis condition and the like of an image analysis by an analyzing unit to be described later, and an analyzing unit that performs an analysis under the analysis condition designated by the condition designation unit. The storage unit includes an image storage unit including a reproduction moving image storage unit that stores a combined moving image obtained by combining the fluorescence image and the visible light image by the combining unit in the image processing unit as an irreversibly-compressed moving image file and an analysis moving image storage unit that stores a fluorescence moving image and a visible light moving image.

Voltage sensitive dyes comprising boron and related compositions and methods are provided. In some embodiments, a voltage sensitive dye comprises an electron acceptor comprising boron. The electron acceptor may be attached (e.g., covalently) to at least one electron donating group and at least one polar group. For instance, the electron acceptor may comprise optionally substituted boron dipyrromethene (e.g., optionally substituted 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene). The point of attachment and chemical nature of the electron donating group(s) and polar group(s) may be selected to impart beneficial properties to the voltage sensitive dye. For instance, the voltage sensitive dye may have an extended difference in the dipole moment between the ground and electronic states due at least in part to the position of the electron donating group(s). The voltage sensitive dyes, described herein, may have high specificity, high signal to noise ratio, fast responsivity, high voltage sensitivity, high photostability, and/or high brightness.

The invention encompasses a rapid and safe preparation method of sperm nuclei, improved sperm nuclei and a method of using the improved sperm nuclei to calibrate a flow cytometer with higher accuracy.
