摘要

In recent research, scientists have explored the potential of triple-walled carbon nanotubes (TWCNTs) for detecting biological viruses. By analysing the vibrational behaviour of TWCNTs, researchers aim to develop sensitive and accurate virus detection methods. These nanotubes exhibit unique vibrational modes that can interact with virus particles. The research utilized a molecular structural mechanics approach to simulate 1392 TWCNT samples, by finite element investigations to ascertain their vibrational modes. The extensive study aimed to offer understanding about how TWCNT-based nano biosensors react mechanically and with sensitivity when exposed to different biological substances. This research has the potential to advance the creation of highly efficient devices for detecting bacteria and viruses. It is suggested that a higher quantity of vacancy defects tends to increase the natural frequency of TWCNTs under fixed-free boundary conditions. Moreover, there is variability in how the natural frequency changes at each level of vacancy and pin hole defects. It’s noteworthy that the range of natural frequencies is wider for mode 1 compared to mode 10.
