Domain structure of epitaxial SrRuO3 thin films

2005

Growth of multidomains in epitaxial thin-film oxides is known to have a detrimental effect on some functional properties, and, thus, efforts are done to suppress them. It is commonly accepted that optimal properties of the metallic and ferromagnetic $\mathrm{SrRu}{\mathrm{O}}_{3}$ (SRO) epitaxies can only be obtained if vicinal $\mathrm{SrTi}{\mathrm{O}}_{3}$ (001) (STO) substrates are used. It is believed that this results from the suppression of multidomain structure in the SRO film. Here we revise this important issue. Nanometric films of SRO have been grown on STO(001) vicinal substrates with miscut $({\ensuremath{\theta}}_{V})$ angles in the $\ensuremath{\sim}0.04\ifmmode^\circ\else\te…

Thermodynamics and Biophysics of Biomedical Nanosystems Applications and Practical Considerations

2019

This book highlights the recent advances of thermodynamics and biophysics in drug delivery nanosystems and in biomedical nanodevices. The up-to-date book provides an in-depth knowledge of bio-inspired nanotechnological systems for pharmaceutical applications. Biophysics and thermodynamics, supported by mathematics, are the locomotive by which the drug transportation and the targeting processes will be achieved under the light of the modern pharmacotherapy. They are considered as scientific tools that promote the understanding of physicochemical and thermotropic functionality and behavior of artificial cell membranes and structures like nanoparticulate systems. Therefore, this book focusses …

Development of different nanosystems for drugs and siRNA delivery

Cancer is one of the leading causes of death in the world. Over the past several decades, the development of engineered nanosystems for targeted drug delivery have received great attention thanks to their possibility to overcome the limitations of classical cancer chemotherapy including poor solubility, targeting incapability, nonspecific action and, consequently, systemic toxicity. In this contest, four different models of nanocarriers have been analysed and compared for their capacity to target tumour tissue and to release the therapeutic agent in a controlled way: INU-EDA-P,C-DOXO; PHEA-EDA-P,C-DOXO; PVP-siRNA and RGO-siRNA. Inulin and PHEA were conjugated to the antineoplastic drug doxo…
