| Abstract | Sensors are an extremely broad field which impacts on many major industrial sectors. This review paper highlights the research carried out during the last 8 years based on recent advances in the development of enzyme and NA (nucleic acid) based biosensors for environmental detection including pollutants and toxic compounds in a wide range of samples. NAbased biosensors are also finding increasing use for the detection of environmental pollutants and their toxicity. Biosensors are now used in a wide variety of disciplines, so that the different types of biosensors are used with their advantages and limitations with different transducers forming the sensing devices, for the different environmental contaminants analysis. The general applications of the enzyme biosensors are highlighted related with an environmental monitoring application. Recent advances in the development and applications of biosensor arrays for environmental detection are highlighted in this review article with special emphasis on functional nucleic acid elements (aptamers, DNAzymes, aptazymes), widely useful in nanobiotechnology and also in lab-on-a-chip technology. |
