With the rise in the global population, the demand for increased supply of food has motivated scientists and engineers to design new methods to boost agricultural production. With limited availability of land and water resources, growth in agriculture can be achieved only by increasing productivity through good agronomy and supporting it with an effective use of modern technology. Advanced agronomical methods lay stress not only on boosting agricultural produce through use of more effective fertilizers and pesticides, but also on the hygienic storage of agricultural produce. The detrimental effects of modern agricultural methods on the ecosystem have raised serious concerns amongst environmentalists. The widespread use of persistent pesticides globally over the last six decades has contaminated groundwater and soil, resulting in diseases and hardships in non-target species such as humans and animals. The first step in the removal of disease causing microbes from food products or harmful contaminants from soil and groundwater is the effective detection of these damaging elements. Nanotechnology offers a lot of promise in the area of pollution sensing and prevention, by exploiting novel properties of nanomaterials. Nanotechnology can augment agricultural production and boost food processing industry through applications of these unique properties. Nanosensors are capable of detecting microbes, humidity and toxic pollutants at very minute levels. Organic pesticides and industrial pollutants can be degraded into harmless and often useful components, through a process called photocatalysis using metal oxide semiconductor nanostructures. Nanotechnology is gradually moving out from the experimental into the practical regime and is making its presence felt in agriculture and the food processing industry. Here we review the contributions of nanotechnology to the sensing and degradation of pollutants for improved agricultural production with sustainable environmental protection.

“…Biosensors for heavy metals have been mainly developed in environmental analysis in water (Evtugyn et al 1999). As far as enzyme biosensors for heavy metal determination are concerned, a certain number of papers have appeared, reporting the use of different enzymes and biosensor configurations/transducers , Compagnone et al 1995and Donlan et al 1989b, Starodub et al 1999, Vel Krawczyc et al 2000, Pirvutoiu et al 2001, and Dzyadevych et al 2003. In several cases the inhibition of enzymes by heavy metals is reversible, even if for rapid restoration of enzymatic activity the use of strong ligands, like EDTA, is required.…”

Biosensoren sind Messfühler, die durch eine enge Kopplung von einem biologischen Erkennungselement (Rezeptor) und einem Signalumwandler (Transducer) gekennzeichnet sind. Sie profitieren vor allem von der hohen Selektivität, mit der Analyte nachgewiesen werden können. Blutzuckermessgeräte für die Patienten‐Selbstkontrolle sind ein Paradebeispiel für erfolgreiche Biosensoren. Andere Biosensoren haben sich als Teil eines Analysensystems bewährt, zum Beispiel die Sensorchips von Oberflächenplasmonresonanz‐ oder Interferometrie‐ basierten Geräten. Zu den Biosensoren, die Analytmoleküle direkt ohne Hilfsreagenzien nachweisen können, gehören auch die Piezosensoren. Thermometrische Sensoren ermöglichen den direkten enzymatischen Nachweis von Analyten, ohne dass ein optisch oder elektrochemisch nachweisbares Produkt entstehen muss. Der Herstellung von Biosensor‐Oberflächen, die ein hohes Verhältnis von spezifischem zu unspezifischem Signal ermöglichen, wird durch neue Techniken ermöglicht, wie das Beispiel der Nanoröhren zeigt. Mit der preisgekrönten Entwicklung von Chips, die Tausende bis Millionen Sensoroberflächen tragen und als DNA‐, Protein‐Chips oder Mikroarrays bezeichnet werden, beginnen sich biosensorische Prinzipien zu etablieren.
