  • Patent number: 11103461
    Abstract: An “inverse” precipitation route to precipitate aqueous soluble species with copolymers as nanoparticles having a hydrophilic, polar core and a less polar shell is described. The aggregation of these nanoparticles to form larger microparticles and monoliths provides a highly loaded construct (e.g., a depot) for the sustained and controlled release of actives.

  • Patent number: 11073517
    Abstract: A method for preparing a nanohybrid used for ratiometric fluorescence and ratiometric electrochemical sensing simultaneously is provided. Surface-aminated (—NH2) SiO2 nanospheres encapsulating an electroactive material A or B are prepared and conjugated with surface-carboxylated (—COOH) carbon dots (CDs) or gold nanoclusters (AuNCs) to prepare a conjugate, and the conjugate is conjugated with a DNA aptamer terminated with —NH2. Ions or biomolecules are added to two types of DNA-conjugate dispersions, and ratiometric florescence sensing is realized by fitting the linear relationship between ratiometric fluorescent peak intensity ICDs/IAuNCs and a specific ion concentration or a specific biomolecule concentration.

  • Patent number: 11071927
    Abstract: A method of separating free target analyte from protein-bound target analyte is described. Such can include obtaining an aqueous sample containing a target analyte in a free form (free target analyte) and the target analyte in a protein-bound form (protein-bound target analyte), passing the aqueous sample through a size exclusion chromatography matrix with a molecular weight cut off sufficient to allow the free target analyte to permeate into pores of the size exclusion chromatography matrix and exclude the protein-bound target analyte, whereupon the free target analyte adheres to and is immobilized by the size exclusion chromatography matrix and the protein-bound target analyte does not adhere to by the size exclusion chromatography matrix, separating the free target analyte from the protein-bound analyte by removing the protein-bound target analyte from the size exclusion chromatography matrix, and eluting the free target analyte from the size exclusion chromatography matrix with an organic solvent.
