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.

边界条件在基于谐振器的纳米棒质量识别中的作用

摘要

添加到纳米传感器的分布质量的识别需要采用适当的逆向技术，该技术必须足够精确以识别分析物。在之前的研究中，我们开发了一种基于特定边界条件下纳米棒自由轴向振动的第一特征频率的方法。在这里，我们通过考虑更广泛的传感器终端条件并检查它们对识别的影响来扩展并完成先前的分析。我们的结果可以指导纳米谐振器的设计不仅具有更高的灵敏度，而且还可以改进重建技术的实施。
