The identification of distributed mass added to a nanosensor requires the adoption of suitable inverse techniques that must be sufficiently precise to identify the analyte. In previous research, we developed a method based on the first eigenfrequencies of the free axial vibration of a nanorod under a specific set of boundary conditions. Here, we extend and complete the previous analysis by considering a wider set of sensor’s end conditions and examining their influence on identification. Our results can guide the design of nanoresonators to have not only a higher sensitivity, but also to improve the implementation of reconstruction techniques.

Abstract
The identification of distributed mass added to a nanosensor requires the adoption of suitable inverse techniques that must be sufficiently precise to identify the analyte. In previous research, we developed a method based on the first eigenfrequencies of the free axial vibration of a nanorod under a specific set of boundary conditions. Here, we extend and complete the previous analysis by considering a wider set of sensor’s end conditions and examining their influence on identification. Our results can guide the design of nanoresonators to have not only a higher sensitivity, but also to improve the implementation of reconstruction techniques.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
