Diseño e implementación de un sistema de control de bobinas Helmholtz para la caracterización de micro y nanopartículas

Abstract

In this work we develop a system of arrangements of two pairs of Helmholtz coils positioned on the “x” and “y” axis for the kinetic characterization of microbots in a liquid medium at different densities. These spherical microbots are synthesized with magnetite magnetic microparticles embedded in a polymeric silicone matrix. One of the most specific contributions is the development of an automated Helmholtz coil arrangement system, which, when moved by stepper motors, the Helmholtz coil system becomes Maxwell coil system as distances are modified, causing distances a uniform field gradient instead of a uniform magnetic field. This system can be used in the redirection of microbots for the elimination of cancer cells by means of the hyperthermia technique; In addition, you can transport medications to specific areas for treatment because these microbots are biocompatible with the human body.
