| Summary: | The detection of pathogenic bacteria is key to the prevention and
identification of problems related to health and safety. Legislation is
particularly tough in areas such as the water industry, where failure to
detect an infection may have terrible consequences. In spite of the real
need for obtaining an analytical result in the shortest time possible,
traditional and standard bacterial detection methods may take up to 7 or 8
days and some even take up to weeks. The advent of new technologies,
namely biosensor, has brought in new and promising approaches. However
much research and development work is still needed before biosensors
become a real and trustworthy alternative. This research report provides an
investigation and a theoretical review of detecting online bacteria through
the instrumentation of an optical fiber probe a kind of biosensor. The
report begins with a description of its background, purpose and scope.
Next, it provides theoretical background on the equipments and items that
are used in the experiments. The experiments determined that the
detection of fluorescence in glass slides and fibers sample was not positive
and positive if cuvette samples were used. |
