  • Glucose biosensor based on platinum nanowires: a clinical study

    We describe the process of modification of the platinum (Pt) nanowire surface and subsequent immobilisation of enzyme glucose oxidase (GOx) on Pt nanowires (PtNWs) for direct glucose measurement. A cyclic voltammetry technique was used to measure electrochemical oxidation between GOx and glucose. PtNW arrays were first fabricated and then functionalised with cysteamine, which in turn acted as a ...

  • Generation of mt:egfp transgenic zebrafish biosensor for the detection of aquatic zinc and cadmium

    Zebrafish embryo toxicity test has become a popular method for detecting the environmental pollutions. But our research showed that zebrafish embryos exhibited no visible paramorphia, malformation or mortality when exposed to heavy metals in a range above the environmental standard limits, indicating that zebrafish embryo an imprecise model in monitoring environmental heavy metals ...

  • Enzymatic inhibition-based electrochemical biosystems: general aspects and applications for the monitoring of aquatic ecosystems

    The use of biosensor-based analytical methods, and specifically of the techniques based on 'inhibition' enzymatic amperometric electrodes, is gaining growing interest in the field of toxicity tests in environmental and food matrices. This contribution proposes the use of inhibition-based enzymatic bioelectrodes for the rapid determination of pesticides, herbicides and toxins in aquatic ...

  • Development of biomarkers in an integrated approach to environmental studies

    This study was conducted in a contained environment in order to develop biomarkers and to evaluate the environmental damage after a release of two different toxic substances which are widely used in industrial production. In a simulation study performed in Tor Mancina area (near Rome, Italy), two dangerous substances (formaldehyde and bromine) were tested. Chemical and physical characterisation, ...

  • Estimation of dead or live bacteria using online Bacteria Activity monitoring - Case Study

    The BACTcontrol, a microLAN instrument, measures on-line bacterial enzyme activity in food and aquatic samples. Besides ß-DGlucuronidase, ß-Galactosidase and ß-Glucosidase to measure E.coli, Coliform and Enterococci activity respectively also alkaline phosphatase (ALP) activity is measured to determine Total Activity. The BACTcontrol TA test measures the metabolism activity of ...

  • Chemyx Syringe Pumps in Neuroscience Research

    Introduction The classical field of neuroscience entails biological or psychological investigation of the nervous system, including the brain, spinal cord and the systemic network of sensory nerve cells called neurons.1 Traditionally, this field comprised of purely biological studies but has since flourished into an interdisciplinary sphere addressing the developmental, ...

  • Tech update: Plant instrumentation - food engineering

    Sensors and other devices are the foot soldiers in automation architecture, but most food and beverage manufacturers still are looking for full value. You know an equipment category has arrived when it starts getting its own industry-specific center. For the food production sensors that do the heavy lifting in instrumentation technology, that day could arrive earlier rather than ...
