A nanorobot control algorithm using acoustic signals to identify cancer cells in Non-Newtonian blood fluid

Multi-robot cooperation is a critical technology for nanorobotics and nanomedicine. Because fluid velocity varies from position to position in blood fluid and nanorobots usually move passively and randomly with fluid to save their energy, it is very challenging for multiple nanorobots to cooperate in blood fluid. Considering these characteristics, this paper presents a nanorobot control algorithm based on the mechanical properties of Non-Newtonian blood fluid. The control algorithm uses acoustic communication to coordinate nanorobots identifying cancer cells in blood vessel. In order to evaluate the effectiveness of the algorithm, comparisons with other methods by simulation were carried out. The results show that the proposed algorithm performs well both in term of the success rate and the cost time for the nanorobots to identify and reach the target.
