Abstract

This paper presents a highly accurate and repeatable method to detect micro-level bio-chemical reactions using the interaction between microstructure and the reactant mixed with the chemical marker. The method produces a recognizable deflection signature of the cantilever beam. Such deflections could be very large such that they exceed the linear deflection range. For determination of the large deflections of the tip of cantilever beams, an exact method is proposed. This method is using symmetry groups for finding the closed-form solution which could be applied for any boundary condition case. The open literature provides solution only for two particular loading cases: point force and point moment..
