7 Future Challenges
The development of novel approaches for environmental monitoring should focus
on the sensitivity and selectivity features, along with equal focusing on the disposal
aspect after the environmental analysis is over. It will be completely futile to have
the ultra-sensitive performance of an analytical probe, but the probe itself is made
of toxic materials that can be harmful to human beings and the environment. For the
aspect of future development, the application of synergistic approach could be a
remarkable solution to define and design standalone strategies to remediate
emerging macro and micropollutants of great concern. Several critical issues of the
traditional approaches applied for the nanoparticle synthesis can be solved by
coupling the whole synthesis procedure with modification strategies involving
surfaces. In order to achieve a deeper insight in this context, the influential and
important aspects of numerous surface modification strategies should be included in
future studies. For the elimination of emerging and priority contaminants, another
interesting possible research alternative is the look-out for unique and new materials
and bio-nanocatalysts following green approach to achieve highly effective and
ecological friendly remediation procedures.
8 Conclusion
The presence of a vast group of emerging contaminants in the natural environment
is of continuous threat for the safety and health of human being along with the
ecosystem. Extensive research work is required specifically dedicated for the
development of treatment technologies in recent years for the elimination of
recalcitrant pollutants in water. In current situations, owing to recent improvements
in analytical instrumentation techniques, it is possible to achieve the desired
“universal screening’’ of environmental pollutant. In terms of analytical probe for
environmental monitoring, the options available are diverse and it will be the choice
of the analyst to make the decision on which system to be employed. Economic,
sustainability and robustness are the major parameters which should be considered.
As compared to traditional chemically-based sensors, biosensors could detect a
wide range of water pollutants or xenobiotic compounds in a unique way with high
sensitivity and selectivity. It can be said that with the progress in the field, metal
nanoparticles will support many novel analytical techniques in the near future, for
the sake of environmental monitoring, and carry out research in new fields for
solving issues related to environmental pollution. From the field application point
of view, the most attractive approach/technique while performing environmental
monitoring is the application of wide-scope screening methodologies, able to screen
and identify as many water contaminants as possible, in order to obtain wide and
realistic information on the actual water quality.
