    摘要: An improved biological aerosol chemiluminescent (CL) detection system having optimal sensitivity and a method for using the same in detecting the presence of biological materials in an aerosol sample. The detection system comprises a cyclone aerosol sampler, a CL reagent injector, and a luminometer, wherein the CL reagent injector is mated with the cyclone aerosol sampler so as to deliver/introduce CL reagent thereto. The inner surface of the cyclone aerosol sampler and the inner surface of the CL reagent injector are fabricated from materials that are free of metals that would initiate a CL-based reaction with a CL reagent to be employed therein so as to provide a CL reagent path free of these metals. The entire CL reagent path in the biological aerosol CL detection apparatus is comprised of these materials. A method for determining the suitability of materials for use throughout the CL reagent path of the biological CL detection system is also taught.

    摘要: A method of: providing a solid surface having a dendrimer molecule bound thereto and a single-stranded probe nucleic acid immobilized to the dendrimer; contacting the solid surface with a sample suspected or known to contain a target ribonucleic acid; denaturing the target ribonucleic acid; and incubating the sample to allow hybridization of the denatured ribonucleic acid to the probe nucleic acids. The target ribonucleic acid is complementary to the probe nucleic acid.

    摘要: The use of sugar-containing hydrogels as very highly porous, aqueous support material for the immobilization of oligonucleotides, peptides, proteins, antigens, antibodies, polysaccharides, and other biomolecules for sensor applications. Unusually large sizes of interconnected pores allow large target molecules to pass rapidly into and through the gel and bind to immobilized biomolecules. Sugar-containing hydrogels have extremely low non-specific absorption of labeled target molecules, providing low background levels. Some hydrogel materials do not have this type of homogeneous interconnected macroporosity, thus large target molecules cannot readily diffuse through them. Additionally, they nearly always experience non-specific absorption of labeled target molecules, limiting their usefulness in sensor applications. A method is provided for preparing sugar polyacrylate hydrogels with functional chemical groups which covalently bond oligonucleotides and peptides. A method for copolymerizing acrylate-terminated oligonucleotides with sugar acrylate monomers and diacrylate cross-linking agents is also provided.

    摘要: A method of: providing a solid surface having a dendrimer molecule bound thereto and a single-stranded probe nucleic acid immobilized to the dendrimer; contacting the solid surface with a sample suspected or known to contain a double-stranded complimentary target nucleic acid; denaturing the target nucleic acids at thermal conditions and in a salt concentration sufficient to denature the target nucleic acids to produce denatured nucleic acids; and cooling the sample to allow hybridization of the denatured nucleic acids to the probe nucleic acids. An article having: one or more paramagnetic microbeads; a dendrimer molecule bound to the beads; and a probe nucleic acid immobilized to the dendrimer.
