Abstract: Micro-cantilever based devices have revolutionized microscopy in the past decade. They heralded the area of nanotechnology by demonstrations of rational control and manipulation of matter at the atomic scale. In spite of the remarkable feats of these devices significant challenges remain

to translate their potential into reality. In this talk we present recent applications of a system theoretic viewpoint to this technology. It will be shown that such a perspective provides unique insights into the dynamics, that can delineate essential limitations and indicate newer methods of imaging. Use of advanced control methods for  nanopositioning will also be presented.
