Biomaterials and Surgical Reconstruction

Our internationally renowned Centre for Biomaterials in Surgical Reconstruction and Regeneration (CBSRR) develops innovative materials and devices that address real medical needs.

Our work

As a multidisciplinary team of academics (cell biologists, chemists, engineersÌýand material scientists) and clinicians, we deliver new knowledge, inventions and clinical solutions by innovating new biomaterials, scaffolds, nanomedicine and devices.

Our strengths

Fundamental understanding

  • Correlation of structure and properties of biomaterials at multiple scales
  • Self-assembling behaviour of nanoparticles and macromolecules
  • Interface between biomaterials and cells / tissues.

Innovations

  • Synthesis and characterisation of novel polymers, bioglass / ceramics, polymer composites, nanomaterials, and nanocomposites.
  • Design, manufacture and characterisation of multifunctional implantsÌýand scaffolds for tissue construction and regeneration, assisted drug discovery & delivery, biosensors and devices.
  • Design, manufacturing and characterisation of nano-vehicles and 3D models for drug discovery and delivery with controlled release
  • Biofunctionalization and modifying the physicochemical properties of materials to direct desirable biological interactions and guide the fate of cells / stem cells.

Clinical translation

  • Preclinical assessments of cell therapy, nanomedicine, implants and devices.
  • Clinical trials of implants and devices.

Our research areas include

Design and syntheses of novel biomaterials

  • Functional elastomers and nanocomposites
  • Degradable natural and synthetic hydrogels
  • Bioactive bioglass and bioceramics
  • Multi-functional nanoparticles, nanocomplex and nanofibres.

Tissue engineering for tissue regeneration and drug discovery

  • Design and fabrication of scaffolds for both soft and hard tissue regeneration including bone, breast, cartilage, cornea, heart valve, maxillofacial, muscle, nerves, tendon, skin, hair follicle, vascular vessels etc
  • 3D tissue / disease models for drug discovery and high-throughput drug screening.

Understanding the biomaterial - biological interface

  • Regulation and direction cell / stem cell fate by ECM and ECM-mimics at multiple scales
  • Dynamic microenvironment and responsive scaffolds for guiding cell/stem cell niche.

Nanomaterials and scaffolds for targeted drug delivery with controlled release

  • Regulation and direction cell / stem cell fate by ECM and ECM-mimics at multiple scales
