Top1. Introduction
Today, biosensors have significant importance in hi- technologies and in the control of the various substances structure in industry, medicine, environmental protection. In 2013, the global market of biosensors is amounted to 11.39 billion dollars. By 2020, according to forecast of Markets & Markets (USA), this figure will increase to 22,68 billion with an average annual growth rate of 10% (Biosensors Market by Application, Product, Technology & Geography, January 2015).
Electrochemical biosensors have the largest market segment and optical biosensors have the fastest growing one. Modern micro and nano technologies offer additional benefits of possibilities in creation of instrumental in intelligent design of biosensors, in which the sensing element is combined with microelectronic circuits that control functional parameters and performing data processing, and providing communication with external equipment. Thus, the biosensors market is growing rapidly, requires all new construction and principles of operation of these devices with enhanced functionalities and improved performances. Increased market demands are forcing manufacturers intensively to expand the order of biosensors with new functionalities. However, even the leading firms in sensitive elements industry are using not more than 27-30% of the available physical phenomena that potentially could significantly expand the range of these devices (the data of the Endress & Hauser AG – a Swiss-based instrumentation and process automation company (Endress, 2004)). Thus, creation of the automated systems of conceptual design of biosensors would unify, reinforce and centralize the development process. Such systems allow reducing the time and workload for the creation of a new product, quick adaptation to the market changes, involving the commercial users into the design process, increasing significantly the knowledge-base for engineering education (Petrova et al., 2015).
