Intelligent materials to regenerate bone tissue

30.03.2007
More than half a million people in the European Union and a million in the United States suffer from disorders in or serious defects of some part of their bone structure. Operations involving grafts or implants, required to mitigate the damage, depend decisively on the materials used.

The European Nanobiocom project, led by INASMET-Tecnalia with the help of others, is working on the regeneration and repair of bone tissue. Seven other bodies, leaders in innovation within this specialism, are also taking part in the project. The goal is to come up with a substitute for bone tissue that can put the bone right and regenerate in such a way that it carries out similar functions as in its natural state. From Spain the Institute of Biomechanics of Valencia and Progénika Biopharma S.A. are also participating.

In the case of substantial deterioration of the bone, it may be necessary for the implant to provide both functional and physiological properties of the damaged item. Given this hypothesis, the bone implants have to comply with a series of requisites capable of contributing to a reconstruction of the deteriorated bone tissue in the most efficient and least discomfiting manner, without any serious repercussion. Another exigency involves the carrying out of the mechanical functions of the damaged bone while the desired regeneration takes place.

The solutions have to be capable, moreover, of remedying particularly serious damage, such as those due to congenital deficiencies, degenerative illnesses, cancerous disorders and other damage caused by accidents. The implants required for this type of solutions are more complex and sophisticated than the small implants known to date. .

The Nanobiocom project aims at developing a support matrix (scaffold) of a compound material that is ‘intelligent’, proactive, and capable of repairing and regenerating bone tissue. To this end, it has to be bioactive, capable of acting on the tissue-generating system and its corresponding genes, as well as respond appropriately to the physiological and biological changes, both internal and external, of that system.

Also necessary are size and shape characteristics, as well as mechanical functions appropriate to healthy bones.

The specific tasks of the project focus on putting the finishing touches to the intelligent material, based on nanoparticles and of a biodegradable nature. Also to be developed is the cell culture in three dimensions, as well as ensuring the biocompatibility of the material.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
