A living biological nano robot as self-navigator sensor for diseases

摘要

In this paper, we experimentally investigated the navigation system of the nonpathogenic strain of E. coli (AW405) and developed a simulator for the locomotion performance of these swimming nanorobots. The swimming behavior of these cells is sensitive to the chemical gradients in their medium. Tissue and disease cells might produce chemical signals in their surroundings. These chemicals have the potential to affect the locomotion behavior of the bacterial cells. Therefore, bacterial cells can be considered as self-navigator nanorobots that are able to discriminate between disease cells such as cancer. Our current experimental and theoretical work is considered as a platform to this novel idea of early detection of problematic diseases.
