The research developed in this work is structured in the following parts:
Chapter 2. In this chapter, the physico-chemical characterization and mechanical
properties of magnetic hydrogels containing sepiolite-magnetite particles are studied.
First of all, in this chapter the synthesis of sepiolite (fiber-like shaped) clay particles
covered by magnetite nanoparticles, carried out by the co-precipitation method, is
described. Afterwards, the adsorption of alginate molecules onto the composite
particles is checked by means of zeta potential measurements. In addition, the most
relevant magnetic properties of the particles are depicted. Then, the preparation of
alginate hydrogels and alginate/(clay-magnetite) ferrogels, by crosslinking of alginate
molecules with calcium ions, is detailed. Finally, the rheological properties, in the
absence and presence of external magnetic field, as well as the microstructural study
of the different hydrogels obtained with embedded particles are presented.
Chapter 3. This chapter includes a similar study to that of chapter 2, but in this case
for suspensions and magnetic hydrogels containing montmorillonite-magnetite
platelets.
Chapter 4. In this one we describe an ex-vivo study, using different techniques, of
the biocompatibility of the suspensions and ferrogels containing sepiolite-magnetite
particles.
Chapter 5 is devoted to remark the most relevant achievements attained and also
the main conclusions drawn from this research work.
Finally, chapter 6 includes the references cited along whole thesis.
