Bone Regeneration

Bone is a highly complex tissue, which undergo microfracture and repair through everyday loading. It is this ability to repair and regenerate its structure that enables bone to spontaneously repair itself following injury without the formation of scar tissue. However, 5-10% of all fractures do not heal in the desired manner. This can lead to the need for surgical intervention where the most common treatment is a bone grafting procedure. There are an estimated 2.2 million such procedures globally each year, which makes bone the second most transplanted tissue after blood. These procedures have inherent disadvantages which gives rise to a great deal of research in this area to develop viable bone graft substitute materials.

Researchers at the MRI are currently developing a variety of materials which may be used to treat different ailments related to bone including:

  • Development of biomimetic bone graft substitutes
  • In situ of proteins, peptides and therapeutic agents
  • Development of biodegradable polymers with tailored properties and degradation profiles
  • Development of artificial meniscus

Peripheral nerve injuries may occur as a result of trauma, infection, or genetic disorders, resulting in pain, sensory loss, muscle weakness and problems with movement. It is estimated that over 700,000 surgical procedures are conducted in the US alone very year, and the annual value of the market is over $700 M. At present, there is no commercially available polymeric device that equals the performance of the autograft, which is the current gold standard. To address this unmet clinical need, the peripheral nerve repair biomaterials programme at the MRI seeks to develop novel polymeric biomaterials and manufacturing methods for the creation of the next generation of medical implants for peripheral nerve repair applications.

Smart Polymers are a new generation of materials which exhibit extraordinary properties. These types of polymers can respond sharply to small changes in physical or chemical conditions with relatively large phase or property changes. Arguable the greatest potential of smart polymers lays in the area of targeted drug delivery. With clinical applications beginning to emerge it is a very exciting time for smart polymer materials research.

Composites Materials & Upscaling
The MRI specializes in the development of innovative thermoplastic composite materials for use in a variety of industrial applications. Polymer composites consist of a matrix polymer material with a reinforcing or non-reinforcing filler dispersed throughout. The matrix polymer acts to provide protection to the reinforcement material from both chemical and environmental attack; bonding to the reinforcement to permit transfer of load; and to hold the reinforcement in a fixed orientation.
Our research encompasses both fibrous and particulate reinforcement, with a focus on basalt fibre, nanoclay and halloysite tubes.
