20090087862 | Chemical Sensing Device - The present invention relates to chemical sensing and in particular to a method for detecting an analyte in a sample of whole blood. The method comprise, in summary, the steps of: exposing the sample to a transducer having a tethered reagent; introducing a labelled reagent; irradiating the sample with a series of pulses of electromagnetic radiation at a wavelength of 600 run or above; and transducing and detecting the electrical signal and the time delay between each pulse. The label on the labelled reagent absorbs the electromagnetic radiation at a level which is at least equal to the absorption of the sample of whole blood at the wavelength of the electromagnetic radiation used. | 04-02-2009 |

20090203154 | Method for Sensing a Chemical - This invention relates to a method for detecting an analyte in a sample. The method comprises the steps of exposing the sample to a transducer having a pyroelectric or piezoelectric element and electrodes which is capable of transducing a change in energy to an electrical signal, the transducer having at least one reagent proximal thereto, the reagent having a binding site which is capable of binding the analyte or a complex or derivative of the analyte, wherein at least one of the analyte or the complex or derivative of the analyte has a label attached thereto which is capable of absorbing the electromagnetic radiation generated by the radiation source to generate energy by non-radiative decay; irradiating the reagent with a series of pulses of electromagnetic radiation, transducing the energy generated into an electrical signal; detecting the electrical signal and the time delay between each pulse of electromagnetic radiation from the radiation source and the generation of the electric signal. The time delay between each of the pulses of electromagnetic radiation and the generation of the electric signal corresponds to the position of the analyte at any of one or more positions at different distances from the surface of the transducer. The label is a nanoparticle comprising a non-conducting core material and at least one metal shell layer. | 08-13-2009 |
