Ethanol plays a key role in various fields. Its use as a fuel is widespread in Brazil since the 70s and, moreover, it is the main component of the alcoholic beverage industry and has great importance in the pharmaceutical, cosmetics and perfumery. From an economic standpoint, the determination of the ethanol concentration is fundamental in operating fermentations plants, whether for quality control, whether to implement automated process control. Many methods for the detection of ethanol were described in the literature, such as GC, HPLC, among others. However these methods hamper the on-line monitoring of ethanol demand and high costs and complexity of installation and operation. The biosensors appear as a promising alternative for these analyzes and present advantages as the possibility of automation and miniaturization of the device, plus a lower cost and response time. This study used techniques of knowledge management and innovation to perform a prospective study on the theme biosensors for ethanol, aiming to score the current state of the art technologies in development and serve as a consultation tool for future projects of R & D within this context. The study was based on searches and analyzes on the basis Scopus and ISI Web of Knowledge publications in the form of technical-scientific articles and patents. After screening, were drawn graphs illustrating the distribution of articles / patents in relation to parameters to assess the state of the technological development and application of bioinstrumentos for ethanol detection .
