Magnetic nanoparticles (MNPs) are very attractive components in many biomedical applications, particularly as therapeutic magnetic microcarriers (TMMC) for targeted therapy. Although MNPs can be effectively gathered and transported using external magnetic fields, the optimal delivery is yet to be fu
One approach to control drug delivery in the cochlea is to use a magnetic microrobot powered by externally applied magnetic fields. However, it is necessary to integrate a localization system to ensure the precise navigation of the microrobot in the cochlear canal. To avoid integrating a clinical im…
This paper presents a novel permanent magnets based actuator capable of injecting and 2D wireless control the motion of an untethered microrobot. The actuator is obtained with a simple, but an effective arrangement of four permanent magnets. Its novelty is that it creates local maxima of the magneti…
This paper presents a novel design of four permanent magnet based actuator for magnetic drug targeting of therapeutic microrobots. Drugs are transported through therapeutic magnetic boluses composed of magnetic particles controlled by magnetic gradients. In this study, to maximize the effect of the…
This work presents a method to guide microrobots by positioning a magnetic actuator using hybrid vision system. The used actuator mounted at a robot end-effector creates local maxima of the magnetic field magnitude, which results in an attractive point for microrobots in its influence zone. The hybr…
The use ofrobotic devices for drug delivery in sensitive area of the human body is an innovative and reliable solution. Most of them use magnetics fields, to steer micro-nano-robots into diseases locations. In this study, we use a magnetic actuator based on two permanent magnets as an end-effector o…
The magnetic particles actuated by an external magnetic field present a promising solution as drug carrier at the inner ear (cochlea). This technique allows non-invasive drug delivery with minimal hydraulic force and very high precision. In this work, magnetic prototyping platform for intra cochlear…
For actuating the magnetic microrobots, two types of magnetic actuation technologies have been used during the last past years. These magnetic technologies may be either electromagnetic coils or permanent magnets based systems. This second solution is not the most used by researchers, because of the…
This paper presents an optimal control strategy for navigation of multiple magnetic microbeads for future drug targeting applications. To transport the drugs, we use therapeutic magnetic microbeads as navigable agents controlled by magnetic gradients. The main difficulty is to control independently
This paper presents an optimal design strategy for magnetic targeting of therapeutic drugs. In this study, to maximize the effect of the treatment and minimize adverse effects on the patient, mathematical models have been developed to find the number and the size of the boluses with respect to the g…
