    摘要: Multifunctional compounds are provided that readily crosslink in situ to provide crosslinked biomaterials. The multifunctional compounds contain a single component having at least three reactive functional groups thereon, with the functional groups selected so as to be non-reactive in an initial environment and inter-reactive in a modified environment. Reaction of a plurality of the multifunctional compounds results in a three-dimensional crosslinked matrix. In one embodiment, a first functional group is nucleophilic, a second functional group is electrophilic, and at least one additional functional group is nucleophilic or electrophilic. Methods for preparing and using the multifunctional compounds, and kits including the multifunctional compounds are also provided. Exemplary uses for the multifunctional compounds include tissue augmentation, biologically active agent delivery, bioadhesion, and prevention of adhesions following surgery or injury.

    摘要: The present invention provides both crosslinked polymer compositions capable of forming hydrogels upon exposure to an aqueous environment and thiosulfonate hydrogel-forming components. The thiosulfonate hydrogel-forming components of the invention are preferably multi-arm thiosulfonate polymer derivatives that form a crosslinked polymer composition when exposed to a base without requiring the presence of a second cross-linking reagent, redox catalyst, or radiation. Methods for forming hydrogel compositions, as well as methods for using the hydrogels, are also provided.

    摘要: A method of developing degradable linear poly(ethylene glycol) PEG (DPEG) with multiple functioning capacities, which can be used as drug carriers for cancer cell delivery. A DPEG may be effective in targeting cancerous tumors through an enhanced permeation and retention effect (EPR). The DPEG will then degrade in the acidic extracellular fluid of solid tumors leading to fast cellular internalizations, finally degrading in the lysosome for efficient renal clearance. These may be used in conjunction with drugs and/or targeting groups. Furthermore, DPEGs are thermoresponsive, on an as needed basis, making them useful for in vivo application.

    摘要: An object of the present invention is to provide a metal particle with which a highly-sensitive testing method can be conducted, and a testing method using such metal particle. The present invention provides a metal particle, which is produced by coating a metal particle labeled with a molecule binding to an analyte with a mixture of two or more types of water-soluble polymer having a mercapto group, a dithiol group or a sulfide group and differing in molecular weight.
