• By changing the protocol of NPs fabrication to prevent the nanotoxicity. For
example, Kansara et al. (2018) developed the biocompatible Fe 3 O 4 NPs using a
safe-by-design approach by the coprecipitation method (Kansara et al. 2018).
2.6.2 Limiting the Nano-Contamination
Nano-contamination can be controlled by restricting the NPs into the environment
that can only be achieved by utilizing sieve-like materials or instruments that can
filter the NPs. One such filter is HEPA (High-Efficiency Particulate Air Filter).
Bortolassi et al. (2017) investigated the potential of HEPA filters to remove NPs.
In this study, three filters were utilized i.e., HEPA 1 filter with 99.995% MPPS (most
penetrating particle size) efficiency, HEPA 2 filter (EPM2000) and HEPA 3 filter
(QM-A). HEPA 1 and HEPA 2 filter were made of glass but HEPA 3 filter was of
micro quartz fibers. From the study, it was confirmed that all the filters blocked the
NPs passage. HEPA 2 filter affirmed the filtration capacity of 99% (Bortolassi et al.
2017). Using this kind of technology, the entry of NPs into the atmosphere or
ecosystem can be controlled.
Another method of controlling the NPs into the environment is recommended by
Mikelonis et al. (2016). According to the study, changes in the fabrication methodology led to a decrease in the Ag release from ceramic water filters (CWFs) and in
disinfection efficiency (Mikelonis et al. 2016). Four different molecules i.e.,
polyvinylpyrrolidone, casein, branched polyethyleneimine and citrate were utilized
to stabilize the silver NPs.

Conclusion
The emergence of nanotechnology is a sign of revolution in the field of technology
that will enter eventually every dimension of life. Nanotechnology has various
commercial applications that cover practically every sector such as catalysis, environment, biomedical, food industries, agriculture, sensing, energy, and photovoltaic.
NPs have the potential to effectively remove the pesticides, dyes, heavy metals, and
decontaminate the air, water, and soil. Besides various applications, nanotechnology
has also countless concerns regarding nanotoxicity. Nanotechnology is an untested
technology that has many downsides. This field is fabricating a significant quantity
of nanosubstances that could potentially be released into the ecosystem and can enter
the groundwater aquifers. According to the various reports, NMs have potential
harmful impacts on the human body and earth system as they interact with the living
system. In view of this, many researchers are doing investigation considering
different parameters for the safety of the environment and public health. Considering
this, the field of nano-toxicology is growing to assess the possible risks of
nanomaterials.
