2010 MICINN-JST Workshop Barcelona, 10 March 2010
the design and chemical synthesis of new functional porous and hybrid materials using different strategies based on:
i) structure-direction agents, ii) self-assembling, iii) sol-gel, iv) intercalation/delamination, v) reeze-drying structuration, vi) templated synthesis.
The tailoring of the porosity at the nanometre scale, the incorporation of specific functionalities, and the improvement of chemical and mechanical stability, constitute one of our main goals. Approaches based on the assembling of materials of biological origin and inorganic solids through supramolecularchemistry, bio-inspired and biomimetic concepts are also used to prepare bio-nanohybridmaterials.
to provide the nanostructured materials with predefined and desirable properties, for applications in: selective adsorption and catalysis, biomedicine and tissue engineering, environmental analysis and remediation, magnetic, optical and electrochemical devices, etc.

Bio-inspired cellular materials
MATERIALS BASED ON COMPOSITE FOAMS MADE OF NATURAL COMPONENTS
FIRE RESISTANT, BIOCOMPATIBLE AND BIODEGRADABLE INSULATING composite foams have been developed by the assembling of a biopolymer matrix withparticles of silicates belonging to the groupof fibrous clays (sepiolite and palygorskite). These low-density materials are fireresistant, biocompatible andbiodegradable, showing mechanicalproperties suitable for diverse andwidespread applications: acoustical andthermal insulationOther applications: food packaging andsupport for solids with electrical, magneticor optical properties, and drugs andbiological species. Tissue engineering.

2010 MICINN-JST Workshop Barcelona, 10 March 2010
Virus-clay bionanocomposites
Bionanocomposites can act as supports of Influenza viruses, in which viruses still exhibit bioactivity.
These materials can be used as novel adjuvants useful as Influenza vaccines.
The presence of specific sialicacid receptors could be applied for selective detection of viruses.
This new approach can tentatively be applied to similar systems for immobilizing other viruses (HIV,..)
