The present disclosure describes methods of use of a composition comprising PARPi-fl to be administered to the oral cavity (e.g., via topical application to surfaces of the oral cavity) followed by imaging of the oral cavity for detection of squamous cell carcinoma of the oral cavity (e.g., in vivo, e.g., in a dental office setting or intraoperatively). The results disclosed herein show that topically applied PARPi-fl and subsequent intraoperative imaging of oral cavities can improve surgical removal of squamous cell carcinoma cells compared to healthy cells.

The present disclosure provides bioorthogonal compositions for delivering agents in a subject. The disclosure also provides methods of producing the compositions, as well as methods of using the same.

Embodiments described herein relate to compounds for the detection of wounds, e.g., chronic wounds or infected wounds, including compositions, substrates, kits, dressing materials, and articles, and systems containing such compounds. Further embodiments relate to methods of using these compositions, kits and systems in diagnostic assays, and in the diagnosis and/or detection of chronic or infected wounds based on enzymatic conversion of specific substrates which are contained in the compositions. Additional embodiments relate to methods of characterizing wounds based on expression of a plurality of markers and using such information to treat, manage, and follow-up patients suffering from chronic or infected wounds.

Corona Phase Molecular Recognition (CoPhMoRe) utilizing a template heteropolymer adsorbed onto and templated by a nanoparticle surface to recognize a specific target analyte can be used for macromolecular analytes, including proteins.

The present invention provides a method for selective delivery of a therapeutic or diagnostic agent to a targeted organ or tissue by implanting a biocompatible solid support in the patient being linked to a first binding agent, and administering a second binding agent to the patient linked to the therapeutic or diagnostic agent, such that the therapeutic or diagnostic agent accumulates at the targeted organ or tissue.

Described herein are fluid complex coacervates that produce solid adhesives in situ. Oppositely charged polyelectrolytes were designed to form fluid adhesive complex coacervates at ionic strengths higher than the ionic strength of the application site, but an insoluble adhesive solid or gel at the application site. When the fluid, high ionic strength adhesive complex coacervates are introduced into the lower ionic strength application site, the fluid complex coacervate is converted to a an adhesive solid or gel as the salt concentration in the complex coacervate equilibrates to the application site salt concentration. In one embodiment, the fluid complex coacervates are designed to solidify in situ at physiological ionic strength and have numerous medical applications. In other aspects, the fluid complex coacervates can be used in aqueous environment for non-medical applications.

A biocompatible analyte sensing material for intradermal or subcutaneous application includes a collection of microgel particles having one or more network crosslinker components and an endogenous or exogenous annealing agent that links the microgel particles together in situ to form a covalently-stabilized scaffold of microgel particles having interstitial spaces therein. A plurality of analyte-specific fluorophores are conjugated to the microgel particles, wherein the analyte-specific fluorophores, in the presence of the analyte and subject to excitation radiation, emit fluorescent light. The analyte sensing material may, in some embodiments, be applied to an excision made in the skin or injected into the skin of a subject.

The present application discloses solid compositions for the oral administration of dyes, and diagnostic use thereof. Preferably, such diagnostic use is aimed at the diagnostic evaluation of the gastrointestinal tract.

The present invention provides peptide hydrogelators capable of forming hydrogels as carriers of active ingredients and acting as sustained or controlled release drug delivery systems.
