    摘要: In a recognition complex system, nucleic acid ligands comprising random DNA sequences are operatively coupled to an organic semiconductor and distributed so as to form an array of recognition complexes. When an unknown chemical or biological analyte is applied to the array, the electrical and/or photochemical properties of one or more of the recognition complexes are altered upon binding of the nucleic acid ligand to the analyte. The degree to which the electrical and/or photochemical properties change is a function of the affinity of the nucleic acid ligand sequence for the analyte. The electrical and photochemical changes associated with the array, as a whole, can be used as a unique signature to identify the analyte. In certain embodiments, an iterative process of selection and amplification of nucleic acid ligands that bind to the analyte can be used to generate a new array with greater affinity and specificity for a target analyte, or to produce one or more nucleic acid ligands with high binding affinity for an analyte. The present invention also provides methods for preparing nucleic acid ligands that bind with high affinity to an analyte and using such nucleic acid ligands to neutralize the analyte.

    摘要: A diagnostic test for environmental bacillus which comprises the steps of inoculating an agar growth medium comprising a nitrate source, luminol and 3-amino-L-tyrosine (3AT) with the sample, incubating the inoculated medium and determining the presence of the bacillus. The novel medium preferably comprises potassium nitrate, luminol, 3-amino-L-tyrosine and trypticase soy agar. Antibiotics and/or a specific bacteriophage may be added to the medium surface in localized areas to show specific bacterial lysis for identification. The novel medium and the methods of this invention are suitable for the identification of B. anthracis.
