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: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
