摘要： The present specification is directed to a novel process to prepare an activated sulfated polysaccharide which may then be used in subsequent reactions or processes to bind the reactive polysaccharide with a nucleophilic agent or an aminated surface. The activating process comprises the steps of initially forming a polysaccharide tetraalkylammonium salt by contacting an aqueous mixture of a sulfated polysaccharide salt with a cation exchange resin to give a polysaccharide free acid and then contacting the polysaccharide free acid with a tetraalkylammonium hydroxide to give the polysaccharide tetraalkylammonium salt, and subsequently forming an activated sulfated polysaccharide by contacting the polysaccharide tetraalkylammonium salt of step i) with a coupling reagent in an aprotic organic solvent at ambient temperatures for a period of time sufficient to form the activated sulfated polysaccharide.

摘要： A sensor for measuring the concentration of an analyte in a medium is disclosed. In one embodiment, the sensor comprises a sensing element including a matrix material and, covalently bonded thereto, one or more monomeric indicator components each of which is capable of providing a first emitted signal of a given wavelength in response to being exposed to an excitation signal. The sensing element is capable of providing a second emitted signal having a longer wavelength than the first emitted signal or signals in response to being exposed to the excitation signal, the second emitted signal being provided by an excimer component produced in the sensing element from the monomeric indicator component(s) and being dependent on the concentration of the analyte in the medium to a greater extent than the first emitted signal or signals. In another embodiment, the sensor comprises a sensing element including two or more different monomeric components at least one or which is a monomeric indicator component capable of providing a first emitted signal in response to being exposed to a first excitation signal. The sensing element is capable of providing a second emitted signal in response to being exposed to a second excitation signal. This second emitted signal is provided by an exciplex produced from the monomeric components. This second emitted signal is preferably dependent on the concentration of the analyte in the medium. An excitation assembly is positioned and adapted to provide the excitation signal to the sensing element. A detector assembly is positioned and adapted to detect the second emitted signal. Preferably, a processor assembly is positioned and adapted to analyze the second emitted signal in determining the concentration of the analyte in the medium.
