Nanotechnology has revolutionaries several sectors of industries, such as the food and agriculture sectors. Food and agriculture sectors are now more sensitive to technology development. These sectors which derive the economic growth are now well-adopting technology in developing crops, integrated pest management, precision agricultural practices, food processing, food packaging, livestock development, etc. In the last decade, nanosensors have emerged as a promising tool for the applications in agriculture and food production. Development of nanosensors and their corresponding biological version as nanobiosensors have opened the new heights in the food and agriculture sector by providing highly sensitive analytical tools alternative to conventional chemical and biological sensors. The nanobiosensors offers have several advantages over conventional sensors. Nanobiosensors exhibit high sensitivity due to strong signal amplification and selectivity. Nanosensors have revolutionized the agriculture sector by providing real-time sensing assets for effective and timely management practices in precision farming. Nanosensors are advantageous because of their low cost and portability. Nanobiosensors offer several detection measures like food contamination, pathogens, heavy metals, pollutants [66], monitoring of physicochemical and biological attributes of soil like temperature, humidity, pH, etc. [67].
Nanobiotechnology
Published in Firdos Alam Khan, Biotechnology Fundamentals, 2020
Nanosensors are any biological, chemical, or surgical sensory points used to convey information about nanoparticles to the macroscopic world. Their use is mainly for various medicinal purposes and as gateways to building other nanoproducts, such as computer chips that work at the nanoscale and nanorobots. Presently, there are several ways proposed to make nanosensors, including top-down lithography, bottom-up assembly, and molecular self-assembly. Medicinal uses of nanosensors mainly revolve around the potential of nanosensors to accurately identify particular cells or places in the body in need. By measuring changes in volume, concentration, displacement, and velocity, and changes in gravitational, electrical, and magnetic forces, pressure, or temperature of the cells in a body, nanosensors may be able to distinguish between and recognize certain cells (most notably, cancer cells) at the molecular level in order to deliver medicine to or monitor development in specific areas of the body.

Many institutions have achieved great research advancements toward the development of nanosensors for many diverse applications within the medical, national security, aerospace, and integrated circuit fields. Engineered nanoscale equipment has many distinct and desirable characteristics, such as improved reactivity, catalytic efficiency, electrical conductivity, vigor, and magnetic properties over bulk material of similar composition. The major advantage of the nanoscale is its relatively massive surface area. Nanosensors are instruments that are used in places where it is difficult to reach, to monitor physical and chemical phenomena. They are also used in the organelles of cells to detect biochemical phenomena and in industries and environmental assessment to measure nanoscopic particles.

Critically, innovative sensors are required[1] because of failure of some conventional methods to monitor and detect contaminants in water bodies.[120] These sensors should possess rapid response to pollutant detection, reliability, high sensitivity, accuracy, and selectivity.[1,82,121] Nanosensors have been increasingly used to monitor water pollutants. Nanosensors show higher sensitivity than thin film-based sensors at the magnitude of three to four orders,[122] and they can provide high signal-to-noise ratio for timely total detection.[123,124] To date, many researchers have made considerable theoretical and practical research on the application of various functional nanomaterials in the field of sensors and have achieved results.

Most common type of packaging materials are those in which the in cooperated active materials are bounded compared to the materials in which nanomaterials are released to food. Nanosensors are included into food packaging matrices which have the specific talent to recognize microbial and/or chemical impurities or environmental conditions that can also responds/make aware about the contamination to the consumer.[79] A novel path to limit the contamination by microbes to food surfaces is by combining the active materials and food packaging materials (Figure 10).

The review has various take-home points. It deals with the synthesis of numerous materials useful in environmental remediation, their efficiency levels in removing various obnoxious materials, steps to improve the efficiency of materials of interest, and on the recovery and recycle of materials of interest up to certain extent. However, the review falls short of clarifying about addressing the disadvantages of several metals and materials that are useful in environmental remediation although there have been feeble attempts to discuss these in spates. These disadvantages that need to be focused on are: 1) as photocatalysis is a surface phenomenon, the thin films are still scuffling with efficiency due to low available surface area and reactive sites; broader application of thin films on industrial scale necessitates their modification119, 2) nanoparticles may risk of agglomeration in suspended form and thus their performance may be substantially reduced, 3) If agglomerated, nanoparticle aggregates may not be transferable through the contaminated zone matrix and cannot act on polluted zone to be remediated.120, 4) nanoparticles, when applied for environmental remediation in the open, may pose health risks due to their potential nanotoxicity as they are not easily recovered post the treatment, 5) nanoparticles may have an adverse effect on the biological entities in instances of biological remediation as these inhibit biological activity121, 6) CNTs at nano size range are often difficult to deal with and, further, the operation condition of nanotube production is expensive, 7) certain technical and economic factors, viz., scale-up, validation and compliances, management priorities, cost, safety and security with respect to environmental and handlers health are numerous bottlenecks in the commercialization or field-scale application of several nanosensors.
