In the present study, the vibrations of the fixed-free single-walled carbon nanotube (SWCNT) with attached bacterium/virus on the tip have been investigated. To explore the suitability of the SWCNT as a bacterium/virus detector device, first the various types of virus have been taken for the study and then the resonant frequencies of fixed-free SWCNT with attachment of those viruses have been simulated. These resonant frequencies are compared with the published analytical data, and it is shown that the finite element method (FEM) simulation results are in good agreement with the analytical data. The results showed the sensitivity and suitability of the SWCNT having different length and different masses (attached at the tip SWCNT) to identify the bacterium or virus.
在本研究中，研究了顶端附有细菌/病毒的固支单壁碳纳米管（SWCNT）的振动。为了探究 SWCNT 作为细菌/病毒检测装置的适用性，首先研究了各种类型的病毒，然后模拟了附有这些病毒的固支 SWCNT 的共振频率。这些共振频率与已发表的分析数据进行了比较，结果表明有限元法（FEM）模拟结果与分析数据吻合较好。结果表明，不同长度和不同质量（附在顶端 SWCNT 上）的 SWCNT 具有识别细菌或病毒的敏感性和适用性。
