Abstract

Methods are described to achieve the quantitative analysis up to femtomolar detection using nanomechanical cantilever. we fabricate a nanomechanical sensor that inherently detects the dynamic response variation of cantilever arrays. Here, the clinical discrimination of PSA Ag-Ab interaction up to femto molar level is accomplished by the resonant frequency shift.
