Abstract: This invention relates to a system and method for detecting a sanitising process and for determining the efficiency of a sanitising process. A sanitising process detection system comprises a substrate with a sensor patch for detection of a disinfecting and/or sterilising agent. The sensor patch produces a colour change on exposure to disinfecting and/or sterilising agent. An optical detector is configured to detect the colour of the sensor patch at one or more predetermined time instants. A processor compares images of the colour of the sensor patch, at a predetermined instant in time, with a datum (such as control or the colour of the sensor patch prior to exposure to the disinfecting and/or sterilising agent) and its output is used to determine the presence of a colour change and thereby indicates the efficacy of the sanitising process.

Abstract: An enzymatic electrochemical sensor for the detection of blood propofol is provided.

Abstract: A system-on-chip contactless physiological sensor (10) is provided which comprises a capacitive-sensor electrode (14) having a first capacitance (C1) and an amplifier device (18) connected to the capacitive-sensor electrode (14), the capacitive-sensor electrode (14) and amplifier device (18) at least in part forming an amplifier circuit for the physiological sensor (10). An artefact-reducing capacitor (20) is then connected in series between the capacitive-sensor electrode (14) and an input of the amplifier device (18), the artefact-reducing capacitor (20) having a second capacitance (C2) which is less than the first capacitance (C1). In this sensor (10), there is no impedance boosting input between the capacitive-sensor electrode (14) and the input of the amplifier device (18).

Abstract: The present invention provides an isolated binding reagent that specifically binds to a recombinant Cocoa Swollen Shoot Virus (CSSV) coat protein antigen having at least 80% sequence identity to the amino acid sequence of SEQ ID NO: 2 or 4 and/or at least 80% sequence identity to the nucleotide sequence of SEQ ID NO: 1 or 3. A porous membrane based sensor for detecting CSSV comprising a recombinant CSSV coat protein antigen and a method for detecting CSSV using the sensor are also provided. A competitive ELISA for detecting viral infections in plants is also provided.
