Abstract
This report gives an overview about biosensors, their types, their construction, development and its future needs. A biosensor is an analytical device for the detection of an analyte that combines a biological component with a physicochemical detector component.
I. INTRODUCTION
This report is a small presentation about biosensors and its types. A biosensor is an analytical device which converts a biological response into an electrical signal. Fig [1]. The term 'biosensor' is often used to cover sensor devices used in order to determine the concentration of substances and other parameters of biological interest even where they do not utilize a biological system directly. Biosensors combine the exquisite selectivity of biology with the processing power of modern microelectronics and optoelectronics to offer powerful and new analytical tools with major applications in medicine, environmental studies, food and processing industries. It consists of 3 parts: the sensitive biological element biological material (e.g. tissue, microorganisms, organelles, cell receptors, enzymes, antibodies, nucleic acids etc.), a biologically derived material or biomimic.[2] The sensitive elements can be created by biological engineering; the transducer or the detector element (works in a physicochemical way; optical, piezoelectric, electrochemical, etc.) that transforms the signal resulting from the interaction of the analyte with the biological element into another signal (i.e., transducers) that can be more easily measured and quantified; associated electronics or signal processors that are primarily responsible for the display of the results in a user-friendly way. This sometimes accounts for the most expensive part of the sensor device; however it is possible to generate a user friendly display that includes transducer and sensitive element.
