sector to stand with an increase growth rate of 25% and carry the potential of
aggravating economic growth to hit the target of three trillion USD by the 2020
(McKee and Filser 2016).
Many cordless sensors have been designed for the monitoring and diagnosis of
diseases, health and prevailing conditions of crop plants along with the evaluation of
nutrient holding capacity of soil. With the aid of nanotechnology it is possible to
track the pathways of pesticides and chemical herbicides in the plants tissues and soil
even when present in trace amounts. The resultant real-time monitoring has boost up
the crop-production by a huge margin by enhancing the production rate and
eliminating the percentile of crop losses. By using nanoherbicides, nanofertilizers
and nanopesticides we are successful in managing food scarcity and hence famine
and drought like conditions with a wide margin. Nanotechnology holds prospects of
fertilization improvement with the soil engineering techniques.
3.4.4 Nanotechnology in Biosphere
Biosphere or life supporting sphere comprises all the living beings interacting in one
or another way with each other either directly or indirectly. For improving life of
crops and protect them from different pesticides and harsh environmental conditions,
market is already flooded with agrochemicals nano formulations in the form of
nanocapsules (Pérez-de-Luque and Rubiales 2009). Nanocapsules filled with
required nutrients are proved to be more efficient than direct application of nutrients
because of the controlled release mechanism of nanocapsules (Liu et al. 2008).
Nanoscience has successfully provided a common alternative to environmentally
harsh rodenticides, miticides and pesticides. Nano-alumina has shown considerate
results for controlling food insects (Stadler et al. 2010). Biocide tracking has been
made possible with the help of nanotechnology using smart dust-as a sensor.
Biocides has been treated and nullified with the help of nanostructured
photocatalytic nanomaterials (Elliott and Zhang 2001).
Applications for Humans Nanomedicine field deals with human body at molecular level involving diagnosis, treatment, regulation and control of body functioning
(Emerich 2005). Biomedical applications of Nps owes to their defense mechanism
against cellular level damages caused by toxic stimulators like radiations, chemicals
or pathological situations such as neurological defects along with retinal
neurodegeneration or cardiac complexities (Pulido-Reyes et al. 2015). Most of the
synthesized Nps are potential anticancerous agents (Gao et al. 2014), like silica NPs
encapsulated with nanoshells, because of its photothermal property (Akerman et al.
2002). Implementation of nanotechnology with medical fields provides extraordinary results for human health as mentioned below:
