The intensive development of science and technology has brought longevity and higher standards of living but paradoxically also generated new threats to human health. Good health is jeopardised by chemical compounds, both organic and inorganic, found in waste by-products of numerous technological processes. Moreover, pharmaceuticals and pesticides introduced into the food chain and their biological change by -products may have a negative impact on human life and the environment.
Therefore it is vital to formulate an integrated natural environment control system allowing continuous monitoring and facilitating observation of the movement of toxic and potentially toxic compounds in the environment, tracing how they are incorporated into the food chain and enabling their chemical analysis. To achieve this aim is necessary to develop new analytical methods for chemical contamination control in food, water and the natural environment in which food is produced.
The special attention is currently focused on the implementation of nanosystems and smart miniaturized systems in the food, natural environment and medical sectors.
Nanosystems is defined as systems that provide information on the analyzed sample involves component build using micro and nano technologies.
Joining in this vivid area, we are working on the development of new materials / analytical devices that could contribute to food and medical diagnosis applications.
Tools will be designed to work as sensors of electrochemical modes of operation. Low cost, quick analysis and miniaturisation of analytical equipment justify such selection.
The working mechanism of the proposed sensors is based on intermolecular ( receptor – analyte) recognition processes occurring at organic /aqueous interfaces.
The synthetic and naturally occurring receptors are applied as the analytically active elements that decide about selectivity of analytical devices. In order to improve the analytical devices properties such as: sensitivity durability, reusability, we are working on new materials for fabrication of matrix for proper receptors immobilization as well as for new efficient transducers.
