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.

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.

Nerve-specific fluorophore formulations of Formula (I) for direct or systemic administration are described. The formulations can be used in fluorescence-guided surgery (FGS) to aid in nerve preservation during surgical interventions.

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.

Polymeric particles are provided for use in therapeutic and/or diagnostic procedures. The particles include poly[bis(trifluoroethoxy)phosphazene and/or a derivative thereof which may be present throughout the particles or within an outer coating of the particles. The particles may also include a core having a hydrogel formed from an acrylic-based polymer. Such particles may be provided to a user in specific selected sizes to allow for selective embolization of certain sized blood vessels or localized treatment with an active component agent in specific clinical uses. Particles of the present invention may further be provided as color-coded microspheres or nanospheres to allow ready identification of the sized particles in use. Such color-coded microspheres or nanospheres may further be provided in like color-coded delivery or containment devices to enhance user identification and provide visual confirmation of the use of a specifically desired size of microspheres or nanospheres.

The present invention is directed to particle comprising a supramolecular complex comprising a monofunctional and/or a bifunctional subunit comprising a quadruple hydrogen bonding unit, an apolar linker, an urea group, and a polyethyleneglycol linker. The monofunctional subunits comprise a functional group. The particles are very suitable as drug delivery system as they bind and enter the cell and may have slow release properties.

The present invention provides an alginic acid-based injectable hydrogel system for labeling an accurate position of a disease lesion and effectively delivering a drug to a target region. The formulation of the present invention can make it easy to locally inject a contrast agent and a drug into a target region while controlling the release rate of the contrast agent or the drug, with the formation of the hydrogel in the injected region. Through the advantages, the labeled position can be accurately determined from images, thereby enhancing the precision of surgical operation, with a minimal incision formed therefor. In addition, when used, the alginic acid-based injectable hydrogel system allows the effective local delivery of a drug to a target region while increasing the long-acting effect of the drug.
