Patent number: 9575081Abstract: The invention provides a device for detecting drugs of abuse or other compounds in saliva. The invention thus provides a device for detecting the presence of one or more analytes in a saliva sample, comprising: (a) One or more pre-treatment regions for specifically or non-specifically removing at least a part of the fraction of the saliva sample interfering with detection of the one or more analytes; and (b) A detection region comprising a biosensor surface, the surface comprising: molecules capable of specifically binding the one or more analytes; or the one or more analytes and/or analyte analogues.Type: GrantFiled: February 26, 2014Date of Patent: February 21, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Jeroen Hans Nieuwenhuis, Ahmed Mohammed Taki Jehanli, Femke Karina De Theije, Eduard Gerard Marie Pelssers

Patent number: 7888040Abstract: The present invention provides immunoassays which are highly specific for detection in biological samples of methamphetamine and other drugs of abuse of the methamphetamine group such as ecstasy and other ecstasy class drugs. More particularly, competitive assays are provided comprising: (a) contacting said sample with (i) a pseudoephedrine/carrier conjugate in which pseudoephedrine is linked via its hydroxyl group to the carrier and (ii) an antibody which is capable of binding both one or more drugs of the methamphetamine group and said conjugate; and (b) determining whether the binding of said antibody to said conjugate is reduced by the presence of said sample, a reduction in binding being indicative that the sample contains a methamphetamine group drug.Type: GrantFiled: June 10, 2005Date of Patent: February 15, 2011Assignee: Concateno UK LimitedInventor: Ahmed Mohammed Taki Jehanli

Patent number: 7790400Abstract: The invention provides competitive immunoassay techniques for high sensitivity detection of delta-9-tetrahydro-cannabinol (cannabis; THC) employing a carrier conjugate of an intermediate in the biosynthesis of cannabis, more particularly 5-pentylresorcinol conjugated to a macromolecular carrier via its hydroxyl groups. By employing such a conjugate with anti-THC antibody in a lateral flow immunochromatography test device convenient on-site testing for low levels of cannabis in liquid samples may be achieved. Such testing is particularly favoured for roadside testing for cannabis in oral fluid samples.Type: GrantFiled: July 1, 2005Date of Patent: September 7, 2010Assignee: Concateno UK LimitedInventors: Ahmed Mohammed Taki Jehanli, Christopher William Hand
