The present invention provides for water-soluble mono- and dicationic fluorescent dyes with the latter exhibiting stable fluorescence at elevated temperatures. The present invention also provides for methods for the production of the fluorescent dyes and for using these dyes in biological assays such as multiplexing qPCR and tissue staining.

This disclosure provides a family of compounds that absorb and fluoresce in the short wave infrared region (SWIR, optionally 1000 nm to 1300 nm), including hydrophilic compounds that exhibit absorption and emission spectral profiles in aqueous solutions substantially similar to those observed in organic solvents such as methanol or DMSO. The compounds can be chemically linked to biomolecules including proteins, nucleic acids, and therapeutic small molecules. The compounds are useful for imaging in a variety of medical, biological and diagnostic applications, including SWIR in vivo imaging of regions of interest within a mammal.

Polymers comprising first and second fluorescent or colored moieties on the polymer backbone and two or more charged moieties on the polymer backbone between the first and second colored or fluorescent moieties are provided. The polymers are useful as fluorescent or colored dyes. Methods associated with preparation and use of such polymers are also provided.

Glucose-sensing luminescent dyes, polymers, and sensors are provided. Additionally, systems including the sensors and methods of using these sensors and systems are provided.

The present disclosure provides polymerizable luminescent dyes useful for incorporation into polymers. The dyes and the polymers can be used in sensing and imaging applications, for example, to provide accurate and optionally long term measurements of glucose in vivo. The present disclosure also provides sensors including the polymers described herein. The sensors can be implanted into a tissue of a subject and used for long-term or short-term continuous and semi-continuous collection of data of various biochemical analytes, optionally without the use of implantable hardware of any type and/or enzymatic and electrochemical detection methods.
