BIOTECNOLOGIE AGRARIE E AMBIENTALI

FACOLTA’ di AGRARIA

(26 Settembre – 30 settembre 2011)

Biosensori e Biotecnologie agro-ambientali

La Scuola Estiva di Biotecnologie  giunta alla sua terza Edizione viene organizzata congiuntamente con ENEA ed NRD  e tratta del ruolo della bionanosensoristica e delle nuove tecnologie applicate all’agro-ambientale.

 

The increasing awareness of the potential presence of toxic chemicals in our environment –the air we breathe, the food we eat, the water we drink – has led to the continuous development of increasingly more complex and sensitive monitoring tools. These toxic chemicals interact with the metabolite, which is a biological compound, and they can be measured by means of the electrical, chemical or physical signals. The technique of biosensors can be used in the field of agriculture but these devices are mostly used in the environmental processes and monitoring to give benefit to the environment. During the reaction in a biosensor, a biological component such as a cell or enzyme is needed. In addition to approaches based on traditional chemical analysis, recent years have also seen an enhanced development of news types of biosensors. Biosensors are powerful diagnostic devices based on the extremely high specificity of biological molecules. Biosensors are used in various fields of biotechnology such as medicine, agriculture and environment and in research. Biotechnology has played role in every sector, whether it is industry, agriculture or environment. Our focus is on the environmental biotechnology. In biotechnology, biosensors are the analytical devices which make use of the biological materials like nucleic acid, hormone or enzyme. The study of natural environment and its applications is called environmental biotechnology. The purpose of environmental biotechnology is used to study the harmful substances which are contaminating the environment and discovering and inventing such processes which can be beneficial for the environment. First we have to see that how the environmental biotechnology is useful for the environment. There are many pollutants which affect the atmosphere, water, soil and make it polluted. These materials together harm the environment and make it contaminated and various diseases can occur in humans and animals due to the environment. It is a common experience that big industries do not have the proper methods to dispose off the waste materials due to which these materials come in the water and make water polluted. In these fields, when the stages of certain analytes are estimated or monitored, biosensors are used for these purposes.. There is no need of any living organisms or molecules during the routine physical analysis of the biological data. For the purpose of physical analysis using biosensors, cells or small molecules are used.The highly specific recognition made possible by receptors, enzymes, antibodies or nucleic acids allowed the construction of highly sensitive biosensors of numerous chemical and biological entities.  To assess the degree of risk, or damage, represented by the introduction of widespread pollutants in agricultural systems, it is therefore necessary methodological approach based on a variety of skills which will address systematically and with modern techniques for analyzing the various aspects related to processes that regulate their movement from the soil surface.
