“…Nanobiosensors can be applied to monitor parameters like temperature, humidity, and other soil components in order to reduce the usage of water and chemicals at specific times and locations . The development of nanobiosensors for the detection of organic pollutants and their application in agriculture includes the detection of acetamiprid, dinosulfon, phenols, and organophosphate pesticides, reaching high accuracies and sensibility. ,− Lipid membrane nanosensors have provided a tool for the detection of insecticides, pesticides, hydrazines, toxins, and polyaromatic hydrocarbons, among other contaminants; they have been implemented in real samples and even at a pilot scale, showing excellent results. This new generation of biosensing has the potential for developing site-specific responses that ensure environmental protection …”

The synergistic interaction between advanced biotechnology and nanotechnology has allowed the development of innovative nanomaterials. Those nanomaterials can conveniently act as supports for enzymes to be employed as nanobiocatalysts and nanosensing constructs. These systems generate a great capacity to improve the biocatalytic potential of enzymes by improving their stability, efficiency, and product yield, as well as facilitating their purification and reuse for various bioprocessing operating cycles. The different specific physicochemical characteristics and the supramolecular nature of the nanocarriers obtained from different economical and abundant sources have allowed the continuous development of functional nanostructures for different industries such as food and agriculture. The remarkable biotechnological potential of nanobiocatalysts and nanosensors has generated applied research and use in different areas such as biofuels, medical diagnosis, medical therapies, environmental bioremediation, and the food industry. The objective of this work is to present the different manufacturing strategies of nanomaterials with various advantages in biocatalysis and nanosensing of various compounds in the industry, providing great benefits to society and the environment.

Inorganic electrode materials of low cost, lower complexity, and high stability have become the more preferred choice over enzyme usage in electrochemical sensors. In this work, copper oxide (CuO) nanorods (NRs) were synthesized on copper foil as electrodes through anodization and annealing processes. The synthesized electrodes were used to analyse the organophosphate pesticides (OPPs) and interference molecules by cyclic voltammetry. The CuO NR sensor was able to identify and quantify different kinds of OPPs with an elevated sensitivity of 1.269, 1.425, 1.657, and 2.833 μA/ng mL-1 for chlorpyrifos, parathion, paraoxon, and pirimiphos and explicitly separate them from interference molecules (i.e., carbaryl, paraquat, sodium nitrate, sodium sulphate, and toluene). Moreover, this electrochemical pesticide sensor achieved a very low limit of detection (LOD) in the 10-7 molar level with a high selectivity among all tested analytes. The LOD for each pesticide ranged from 0.29 to 0.61 μM, revealing the ability to define the maximum residue limit in food. In short, our enzyme-free CuO NR sensor is a promising platform to deliver a fast, low-cost, and reliable pesticide detection unit.

“…22 Moreover, ZnO nanorods were employed in detecting glucose. 23 Nevertheless, these examples, albeit based on inorganic MOS structures, require the use of enzymes which can be chemically unstable in certain circumstances and, therefore, a source of problems for commercialization due to the long-lasting and portability requirements 24,25 of these types of sensors. Therefore, reagentless non-enzymatic sensing methodologies based on nanoscale MOS structures are desirable for achieving the point-of-care needs.…”

Nanoscale inorganic semiconductors (with interfacial thickness <10 nm) have superior stability compared to soft organic compounds and are important for the development of enhanced reagentless sensing devices. As a proof of concept, this study demonstrated that the density of states of a copper oxide mixed valence semiconducting nanoscale film can be suitably designed as a transducer signal for reagentless sensing of phenol.
