Abstract

Recent advances in nanoscience and nanotechnology have expanded our ability to develop multifunctional nanostructures that combine therapeutic and diagnostic functions into a single nanostructured complex. These materials, called "teranostics", have been interesting for many applications, especially in the early diagnosis and treatment of diseases, including cancer. The versatility of these nanomaterial-based structures stems from the possibility of incorporating various types of molecules into the surface of a single nanoparticle, making them perform multiple functions. This research project aims at investigating the interaction of new nanostructured materials composed of spherical nanoparticles or nanorods- with normal and cancer cells, or with reconstituted cell membranes. The incorporation of specific antitumor or antigen structures in the nanosystems will also be carried out, allowing them to target specific cells. Emphasis will be given to understanding the interaction between these compounds and cells and / or cell membranes by spectroscopic, microscopic and calorimetry techniques, aiming at obtaining systems with high stability and well defined properties that are required for nanomedicine applications. These nanoconjugates will be further evaluated for their in vitro toxicity as well as their specificity and interaction with different tumor and normal cell types. (AU)
