‘Intelligent’ materials to revolutionise surgical implants

04.12.2008
nanotechnology will provide superior implants for orthopaedic patients

A brand new process that could revolutionise the reliability and durability of surgical implants, such as hip and knee replacements, has today , 2 December 08, received recognition for its medical and commercial potential by achieving one of the world’s most sought after accolades.

A team of researchers, led by the Science and Technology Facilities Council (STFC), has received a Medical Futures Innovation Award for its high technology process designed to coat surgical implants with fibres that, for the first time, will encourage the implant to ‘bond’ with living bone and to last the lifetime of the patient.

This unique surface engineering process is being developed at the Micro-Nano Technology Centre (MNTC) at STFC. In collaboration with the Electrospinning Company Ltd (TECL) and Anglia Ruskin University, the concept will be taken forward under the guidance of a Medical Futures team, and eventually exclusively licensed to TECL, a spin out company of STFC.

This advanced nanotechnology technique builds on an existing technique known as electrospinning, and will utilise a vastly superior electrospinning source to create bespoke fibrous materials. Electrospinning is a process that uses an electrical charge to turn polymers into extremely thin fibres that are ‘spun’ to form a mat of fine fibres. It is seen as a platform technology for the medical sector with a wide range of applications including tissue regeneration and drug delivery. The MNTC has developed systems to increase the production rate of nanofibres which has been previously prevented this technology from being adopted by industry.

In this case, nanosized hair- like structures, a thousand times thinner than the width of a human hair, are electrospun at MNTC and added to the surface of an orthopaedic implant to create a ‘living interface’ between the artificial implants and living bone. Not only does this improve the performance of the implants it also significantly increases their durability to last the lifetime of the patient. Any stress on the implant is relieved, making it more reliable and durable. Additionally, it is also possible to add a unique biological coating that can facilitate growth and improve the bonding of healthy tissue to the implant, primarily benefitting patients with osteoarthritis in the aging population and sports injuries in the younger population.

This process will be transferred to UK industry and TECL will provide access to state-of-the-art electrospinning systems. TECL has spun out from STFC to provide open access to electrospinning equipments and expertise to organisations that would like to explore the technique’s potential. The main benefit is that this can be done without commercial companies committing to capital investment or developing in-house expertise until the potential value of electrospinning to the organisation is fully understood. TECL is based both at the Daresbury Science and Innovation Campus in Cheshire and at STFC’s Rutherford Appleton Laboratory in Oxfordshire, and was founded by CLIK, the wholly-owned technology exploitation company of STFC. TECL’s specialised facilities are designed to extend current electrospinning capabilities so that nanofibres can be reproduced in volume.

Dr Robert Stevens, Head of the MNTC at STFC said: “This award provides a major step forward for the future of patients requiring surgical implants and I am thrilled that this concept was selected as an award winner over several hundred entries. Our award is given for translational research innovation to meet the current and future orthopaedic needs of patients.”

Mansel Williams, Chief Executive of The Electrospinning Company said: “Ten percent of patients receiving surgical implants go on to develop infection and loosening of their implants, costing the UK at least £14 million every year, £224 million globally. We want to eliminate this by creating the ideal implant surface matched to the individual patient, benefitting both the patient and the economy. This award will now allow us to scale up the testing and commercialisation of these implants”

The Medical Futures Innovation Awards, which were announced at the Medical Futures Innovators Gallery in London, are one of the UK’s most highly coveted medical awards, rewarding ground-breaking innovation from front line clinicians and scientists with ideas that have the potential to transform peoples' lives and demonstrate the UK's position as a world beater.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
