Preface
Sensors have become an integral part of civic society to check on social, environmental, and strategic activities. The environmental sensors are required to ensure
the safety and security of the ecological environment around us. Water being the
key component for life existence on earth needs to be ensured for its quality as well
as quantity to meet global demand. However, with increased intervention of
humans, its quality is getting deteriorated, while ground water table is going down
owing to over exhaustion of water resources. Thus development of sensors for field
testing of these parameters is essential. The figure of merits associated with any
sensor, such as sensitivity, selectivity, detection limit, reproducibility, accuracy,
precision, reusability, etc., is mainly defined by the type of sensor material and the
transduction mechanism used. Amongst various analytical techniques, colorimetry,
absorbance, fluorescence, surface-enhanced Raman scattering, electrochemical, and
electrical techniques are widely adopted to develop a water quality monitoring
sensor. Various materials, beginning from organic ligands to the nanomaterials
(nanoparticles, quantum dots, nanotubes, nanowires, thin films, nanofibers, etc.),
are widely adopted to develop a sensitive sensor. For selectivity, various chemo
linkers and bio receptors (antibodies, enzymes, aptamers, oligomers, etc.) are utilized for field usability of the developed sensor platform. This book provides a
comprehensive overview of the above sensing techniques, materials, and receptors
for water quality/pollutants monitoring, and it would be a handy guide for the
students, researchers, engineer, etc., working in field of environmental engineering,
material science and engineering, and water.
