Abstract

Development of design features of nanosensors for oil branch is shown. It is established that in modern nanosensors usually influence formation of a working signal as environment qualitative quantitative indices (values of temperature, pressure, speed of migration of fluids, contents of chemical elements, sizes рН, etc.) and the nature (predetermining properties), structure and extent (the geometrical sizes) of nanoparticles of sensitive elements which the studied environment influences, forming as a result this working signal. The basic design of nanosensors and the mechanism of their work is described. Distribution of nanosensors on classes depending on the principles and mechanisms of action and work, and also the used materials and a design is presented. Carry nanodevices which on the basis of manifestation of the existing physical princi- ples and mechanisms will transform external influences, various on character and extent of manifestation, to separate electric working signals to the first class. From tradi- tional electronic sensors they are distinguished by use as sensitive elements of nanoparticles or some modified substances on their basis. Carry photometric and chemical nanosensors which in most cases directly interact to the second class (react) with molecules of substances (connections) or electromagnetic fields. Such nanosensors, by means of some optical effects (for example, effect of a luminescence), signal about existence in the studied environment of required substances (chemical compounds). The light source is often necessary for "reading" indications of these nanosensors (for example, the laser and the photosensitive device). The design of nanosensors of pressure, temperature and a chemical composition of the studied fluids is opened.
