Professor Guillermo Ramón Iglesias Salto, from the Department of Applied Physics at the University of Granada, welcomes postdoctoral candidates interested in applying for a Marie Skłodowska-Curie Individual Fellowships (MSCA-IF) in this university. Applicants must comply with the Mobility Rule (more information in the participant guide: http://sl.ugr.es/097k).

The research activities of the group have focused on different lines, always regarding the physical properties of the solid/liquid interface and their implications in the characteristics of dispersed systems and their engineering applications.

Ours efforts have been devoted to the synthesis of nanoparticles of different chemical compositions, but always with controllable size, shape and surface functionalities. Additionally, the group has also tried to transfer their knowledge to industrial partners.

Specifically, under the project RyC-2014-16901, my interest has mainly dealt with two different lines regarding with the project “New technologies based on nanoparticles systems”, Biomedical Applications. Specifically in two aspects:

1.         Design and evaluation of nanoparticle-based drug transport vehicles, in which the inclusion of one or more magnetic cores permits control of the particle location, and approach to a specified target. A biodegradable polymer coating is added for loading and releasing the transported drugs.

 2.        Secondly, our interest has been invested in the preparation of (electric and magnetic) field-responsive fluids. These magnetorheological and electrorheological suspensions are capable of undergoing fast and reversible transition from moderately viscous Newtonian fluids to plastic or viscoelastic ones. This behavior makes them applicable as hydraulic fluids with variable viscosity in a wide range of applications, related to damping or motion transmission. The Spanish oil company Repsol has demonstrated its interest through a long-lasting financial agreement.

The analysis, characterization and manipulation of nanoparticles (NPs) is without doubt the step prior to the generation of new materials with a wide range of applications in areas such as medicine (diagnosis or treatment), biotechnology, electronics, energy storage, etc., Up to now, most applications have been limited to the use of suspensions of spherical particles, extensively studied in the theoretical and experimental field. However, in many situations, the geometry of the NPs is critical to improve these properties.

The scientific fields where the geometry is controlled, and often the non-sphericity, are of interest to grow as we advance in the knowledge of the materials and their synthesis techniques. There are even situations in which all phenomenology is based on the non-sphericity: just think of the phenomena of electro-orientation as the birefringence or the formation of phases liquid crystal, etc. This is particularly true in the area of so-called biomaterials, that is to say, in the development of systems for controlled release of drugs, tissue engineering and medical diagnostics. There also another scientific field in which recently, the use of magnetic nanoparticles has found an important therapeutic application. It is hyperthermia, consisting of the local heating induced by the particles when subjected to an oscillating magnetic field. Depending on the size and shape, this heating is produced by friction of the particles with the fluid, or by magnetic hysteresis, or even by the effect Néel (in the case of particles, superparamagnetic, therefore no hysteresis). Simply raise the temperature to about 45 ° C for 30 minutes to produce the death of the tumor cells. As a result, there occurs a heating of the particles even close to its melting temperature.
