“…There are various literature attributing the progress of nanosensor in agriculture for instance detection of DDT using gold nanoparticles based sensor according to study conducted by Baker et al (2013c). Similarly, the use of carbon nanotubes has become one of the most popular in developing a sensor to monitor environmental samples such as methyl parathion, paraoxon and their metabolites (Zhang et al, 2014).…”

Increment of technical knowledge has remarkably uplifted logical thinking among scientific communities to shape the theoretical concepts into near product-oriented research. The concept of nanotechnology has overwhelmed almost all forms of lives and has traded its applications in myriad fields. Despite rapid expansion of nanotechnology, sustainable competitions still do exist in the field of agriculture. In current scenario, agriculture is a manifestation demand to provide adequate nutrition for relentless growing global population. It is estimated that nearly one-third of the global crop production is destroyed annually. The loss owes to various stresses such as pest infestation, microbial pathogens, weeds, natural calamities, lack of soil fertility and much more. In order to overcome these limitations, various technological strategies are implemented but a majority of these have their own repercussions. Hence there is a scrawling progress on the evaluation of nanoparticles into agriculture sector which can reform the modern agricultural system. Applications of these nanomaterials can add tremendous value in the current scenario of a global food scarcity. Nanotechnology can address the adverse effects posed by the abundant use of chemical agrochemicals which are reported to cause biomagnification in an ecosystem. Based on these facts and consideration, present review envisages on nanoparticles as nanoherbicides, nanopesticides, onsite detection agro-pathogens and nanoparticles in post harvest management. The review also elucidates on the importance of nanoparticles in soil fertility, irrigation management and its influence on improving crop yield. With scanty reports available on nanotechnology in agriculture system, present review attributes toward developing nanoagroparticles as the future prospect which can give new facelift for existing agriculture system.

“…As mentioned above for the direct electrochemical detection of pesticides, nanotechnology has allowed the construction of new bioelectrochemical interfaces with improved stability of the immobilized bioreceptor, faster electronic transfer rates and overall enhanced analytical performance [52,53]. Also, a variety of electrochemical techniques have been explored in the development of pesticide biosensor approaches, including differential pulse voltammetry, square-wave voltammetry, amperometry, potentiometry and electrochemical impedance spectroscopy .…”

Monitoring chemical contamination in water is a must to guarantee the supply to the society of this more and more scarce prized asset. The European Union as well as other bodies have released reports and directives defining lists of substances whose detection in waters should be prioritized and posing limits to the maximum allowable concentrations that drinking water must have. The scientific community has been actively working on the development of analytical tools that could be applied in the detection of hazardous chemical species in waters. Here, an overview of electrochemical devices with the potential of being implemented to the monitoring of the forty five pollutants include in the list of priority substances set in the 2013 EU directive that could be grouped into heavy metals, pesticides, hydrocarbons, halogenated hydrocarbons and alkyl phenols, is given, aiming at showing their benefits and limitations in this scenario.

Nowadays extensive volumes of pesticides are employed for agricultural and environmental practices, but they have negative effects on human health. The levels of pesticides are necessarily restricted by international regulatory agencies, thus rapid, cost-effective and in-field analysis of pesticides is an important issue. In the present work, we propose a butyrylcholinesterase (BChE)-based biosensor embedded in a flow system for organophosphorus pesticide detection. The BChE was immobilized by cross-linking on a screen-printed electrode modified with Prussian Blue Nanoparticles. The detection of paraoxon (an organophosphorus pesticide) was carried out evaluating its inhibitory effect on BChE, and quantifying the enzymatic hydrolysis of butyrylthiocholine before and after the exposure of the biosensor to paraoxon, by measuring the thiocholine product at a working voltage of +200 mV. The operating conditions of the flow system were optimized. A flow rate of 0.25 mL/min was exploited for inhibition steps, while a 0.12 mL/min flow rate was used for substrate measurement. A substrate concentration of 5 mM and an incubation time of 10 min allowed a detection limit of 1 ppb of paraoxon (corresponding to 10% inhibition). OPEN ACCESSChemosensors 2015, 3 130The stability of the probe in working conditions was investigated for at least eight measurements, and the storage stability was evaluated up to 60 days at room temperature in dry condition. The analytical system was then challenged in drinking, river and lake water samples. Matrix effect was minimized by using a dilution step (1:4 v/v) in flow analysis. This biosensor, embedded in a flow system, showed the possibility to detect paraoxon at ppb level using an automatable and cost-effective bioanalytical system.
