Swimming micro ana nanorobots have been promising hope in medical field in terms of non-invasive surgery, targeted drug delivering and bio-sensing. Nanorobots can be detected by detecting the magnetic field due to their magnetic components or coat of the nanorobots. However, scalar quantity of the magnetic field is extremely small. There aren’t many research to detect extremely small magnetic fields. In this article, two methods of detecting small magnetic fields have been discussed which are optical magnetic field sensor and SQUID. In 2009, Sylvain Martel published an article claiming that we can use magnetic particles and magnetic field to create nanorobots. He states that with the help of MRI for feeding back to information to a controller which is responsible for control and navigation in the blood vessels of magnetic carriers, nanorobots and magnetic bacteria. Therefore, with the help MRI of magnetic carriers, nanorobots and magnetic bacteria, scientists can be used in medicine to send medicine to cells in human body [1]. Also, there are other scientist who studied nanorobots such as Sámuel Sánchez, Famin Qui and Bradley Nelson. Sámuel Sánchez created a nano-bio device that can be used in medical field in Max Planck Institute for Intelligent System in Germany. Famin Qui and Bradley Nelson studied magnetic helical micro and nanorobots for biomedical applications. [3].
