摘要： The present invention provides apparatus, kits and methods for assaying analytes using photoelectrochemical molecules as labels. Specifically, the present invention provides a method for assaying an analyte, comprising: a) contacting a sample suspected of containing an analyte with a reactant capable of binding and/or reacting with the analyte under suitable conditions to allow binding of analyte, if present in the sample, to the reactant; and b) assessing binding and/or reacting between the analyte and the reactant to determine presence and/or amount of analyte in the sample, wherein the reactant, analyte, or additional reactant or additional analyte or analyte analog is labeled with a photoelectrochemically active molecule. The assessing step also comprises converting the photoelectrochemically active molecule with light to an excited state in the presence of an electrode, and assessing an electric current generated by an electron transfer between the excited photoelectrochemically active molecule and the electrode.

摘要： A method for the preparation of shaped polymeric particles, and in a particular embodiment shaped electrostatographic toner particles, of controlled morphology including the following steps. A selected solvent or solvent mixture is used to dissolve a polyester polymer material to form an organic phase, wherein the polyester material is formed from at least one diol and at least one multicarboxylic aromatic acid and has a solubility parameter of greater than 9.0 (cal/cm3)1/2, the selected solvent or solvent mixture includes at least a first solvent having a solubility parameter of less than 9.0 (cal/cm3)1/2, and the difference in solubility parameters for the polyester material and the at least first solvent is between 1.0 and 3.0 (cal/cm3)1/2. The organic phase is dispersed in an aqueous phase containing a particulate stabilizer to form a dispersion, which is then homogenized. The organic solvent is evaporated from the dispersion to form shaped polymeric particles, and the resultant product is recovered, washed and dried.
