and extraordinary optical and electrical properties (Weng and Ren 2006). Apart from
this they have been explored for detecting cancer biomarkers from blood samples or
tissue biopsies (Smith et al. 2006). Quantum dots when tagged with antibodies can
easily target and image the tumours simultaneously on screen or radiographic sheets
(Chan and Nie 1998). In vivo tracking of progenitor cells is made possible with the
help of iron Nps using MRI technique.
3.4.8 Other Applications
3.4.8.1 Nanotechnology as Energy Sources and Energy Convertors
Not only in treatment but nanotechnology has also inserted its claw in the development of green energy sources. Energy sector of world is highly boosted up because
of the involvement of nanofield. Nanotechnology has been successfully explored for
the designing of materials and technology for cleaner energy production, energy
storage for saving, energy conversion along with improvement of energy efficiency
(Pathakoti et al. 2018).
One of the attention seeking work in this field is usage of nanotechnology for
controlling the extensive energy carrying X-rays and γ-rays by obstructing, storing
and converting them for bio imaging or other related applications (Maldiney et al.
2014). Nanotechnology has provided successful, clean and efficient alternative to the
energy sources such as improved and proficient solar cells, fuel cells and batteries.
Aerogels fabricated with the help of nanotechnology for insulation purpose is far
ahead from its other counterparts for their porous nature and lightweight, which aids
up in saving energy to a remarkable level. Using nanomaterials, more lightweight,
durable, stronger and efficient blades are being designed for the easy and fast
movement of wind turbines, thus cutting the pollution costs caused by fossil fuel
fed energy channels.
3.4.8.2 Nanotechnology for Remediation of Contamination
In this field, nanotechnology acts as an important and unquestionable tool for the
remediation of the contaminated water or soil either on-site (in situ remediation) or
off-site (ex situ remediation). Nps application for remediation is more successful
because of its ability to reach upto the points where larger particles fail to reach.
Moreover the efficiently coated Nps avoid interactions with unwanted entities
present in the medium. Ground water has been efficaciously treated to filter out
chlorinated solvents leached out from menacing waste sites. Zerovalent iron Nps
have been explored by Li et al. for the dechlorination of perchloroethylene and
trichloroethylene to produce carbon dioxide with faster reaction rates (Li et al. 2006).
Waste sites with heavy accumulated dose of lead, arsenic and chromium have been
successfully immobilized with the help of nanoscale iron particles (Kanel et al. 2006;
Rickerby and Morrison 2007).
