Biosensors function by coupling a biological sensing element with a detector system using a transducer. The first scientifically proposed as well as successfully commercialized biosensors were electrochemical sensors for multiple analytes. Nowadays, the importance of a monitoring and regulating many different parameters in areas such a food industry a, clinical diagnoses, hygiene, environmental protection, drug development, or forensics is increasing. Therefore, there is a need to have reliable analytical devices available, which are able to perform quick and accurate analyses. A biosensor is a device that measures biological or chemical reactions by generating signals proportional to the concentration of an analyte in the reaction. Biosensors are employed in applications such as disease monitoring, drug discovery, and detection of pollutants, disease-causing micro-organisms and markers that are indicators of a disease in bodily fluids (blood, urine, saliva, sweat). it consists of the following components. One of the ways how to overcome many disadvantages of the conventional methods is to use proper designed biosensor. The main reason why biosensors are still rarely used in mentioned areas is their often impracticability for real samples, whereas a biosensor developed for standards is not automatically applicable for real samples. Biosensors, a hybrid of physical and chemical sensing technique, is among one of the recently described class of the sensor. IUPAC provide recognition to this type of sensors only some seventeen years prior to today. In principle, biosensors are receptor-transducer based tool which could be employed for interpreting the biophysical or biochemical property of the medium. Moreover, the most intriguing character that sets this type of sensors apart from others is the presence of biological/organic recognition element which enables the detection of particular biological molecules in the medium Development of biosensors brought a new era of advancement in science.
