Analytical nanobiotechnology for medicine diagnostics.

The review is concerned with the state-of-the-art and the prospects of development of nanotechnologies in clinical proteomics. Nanotechnology in clinical proteomics is a new medical research direction, dealing with the creation and application of nanodevices for performing proteomic analyses in the clinic. Nanotechnological progress in the field of atomic force microscopy makes it possible to perform clinical studies on the revelation, visualization and identification of protein disease markers, in particular of those with the sensitivity of 10(-17) M that surpasses by several orders the sensitivity of commonly adopted clinical methods. At the same time, implementation of nanotechnological approaches into diagnostics allows for the creation of new diagnostic systems based on the optical, electro-optical, electromechanical and electrochemical nanosensoric elements with high operating speed. The application of nanotechnological approaches to creating nanopore-based devices for express sequencing of the genome is discussed.
