Detection of abused substances and their metabolites using nucleic acid sensor molecules
First Claim
1. A method of detecting the presence of a compound in a biological sample, the method comprising:
- (a) contacting the sample with an nucleic acid sensor molecule, and (b) assaying for the presence of the drug under conditions suitable for detecting the presence of the drug in the sample, wherein the nucleic acid sensor molecule comprises a enzymatic nucleic acid component and one or more sensor components that upon interaction with the compound induces a chemical reaction of the enzymatic nucleic acid component that modulates the activity or properties of the reporter molecule, signaling the presence of the compound.

Abstract
Nucleic acid sensor molecules (allozymes, allosteric ribozymes, allosteric DNAzymes), aptamers and methods are provided for the detection and quantitation of small molecules, including drugs, drug analogs, and drug metabolites, for example recreational drugs, mood-altering drugs, and performance enhancing drugs such as 4-MTA (4-methylthioamphetamine), Alpha-ethyltryptamine, Amphetamine, Amyl nitrite, Benzocaine, Cocaine, Dimethyltryptamine, Ecstasy (MDA, MDMA, MDEA), Ephedrine, Erythropoietine (Epogen), Fentanyl, Gamma Hydroxybutyrate (GHB), GBL (Gamma butyrolactone), GHB (Gamma Hydroxybutyrate), Hashish, Heroin, Isobutyl nitrite, Ketamine, Lidocaine, LSD (Lysergic acid diethylamide), Mannitol, Marijuana (THC), Mescaline, Methadone, Methamphetamine, Methaqualone, Methcathinone, Methylphenidate (ritalin), Morphine, Nexus (2CB), Nicotine, Opium, Oxycodone, OxyContin, PCP (phencyclidine), Peyote, Phenobarbital, Procaine, Psilocybin, Psilocybin/psilocin, Pseudoephedrine, Rohypnol, Scopolamine, Steroids, Strychnine, and Talwin. Also provided are kits for detection. The nucleic acid sensor molecules, methods and kits provided herein can be used in diagnositic applications for detecting drugs, analogs, and metabolites thereof.
