Abstract Magnetic navigation systems are used to precisely manipulate magnetically responsive materials enabling the realization of new minimally invasive procedures using magnetic medical devices. Their widespread applicability has been constrained by high infrastructure demands and costs. The study reports on a portable electromagnetic system, Navion, which is capable generating large field over workspace. system easy install in hospital operating rooms transportable through health care...
Abstract Metals and polymers are dissimilar materials in terms of their physicochemical properties, but complementary functionality. As a result, metal-organic structures can introduce wealth novel applications small-scale robotics. However, current fabrication techniques unable to process three-dimensional metallic polymeric components. Here, we show that hybrid microstructures be interlocked by combining 3D lithography, mold casting, electrodeposition. Our method used achieve complex...
Abstract The past decade has seen an upsurge in the development of small‐scale magnetic robots for various biomedical applications. However, many reported designs comprise components with biocompatibility concerns. Strategies fabricating biocompatible and degradable microrobots are required.

Numerical simulation was used study motion controlled flowing through...
Abstract Magnetic microrobots have been developed for navigating microscale environments by means of remote magnetic fields. However, limited propulsion speeds at small scales remain an issue in the maneuverability these devices as force and torque are proportional to their volume. Here, a microrobotic superstructure is proposed, which, analogous supramolecular system, consists two or more units that interconnected organized through physical (transient) component (a polymeric frame thread)....

Iron oxide nanoparticles hold great potential for future biomedical applications but, to date, usually suffer from reduced magnetic properties compared their bulk counterparts. The replacement of Fe(III) ions with Zn(II) can enhance while keeping biocompatibility characteristics. Yet, common synthesis methods these highly particles require using environmentally harmful solvents, multiple steps, and postfunctionalization, all being affected by poor scalability high polydispersity. To address...
Electromagnetic Navigation Systems for Minimally Invasive Surgery Magnetic navigation systems (MNSs) are used to precisely manipulate magnetically responsive materials enabling the realization of new minimally invasive procedures.
