Evaluating the effect of increasing ceramic content on the mechanical properties, material microstructure and degradation of selective laser sintered PCL/b-TCP materials
(Elsevier, 2015-06-06)
Orthopaedic scaffold materials were fabricated from polycaprolactone (PCL) and composite PCL β-tricalcium phosphate (PCL/β-TCP) powders using selective laser sintering (SLS). Incorporating β-TCP particles is ...
On the role of the actin cytoskeleton and nucleus in the biomechanical response of spread cells
(Elsevier, 2014-02-11)
Micropipette aspiration (MA) has been used extensively in biomechanical investigations of un-adhered cells suspended in media. In the current study, a custom MA system is developed to aspirate substrate adhered spread ...
Computational investigation of in situ chondrocyte deformation and actin cytoskeleton remodelling under physiological loading
(Elsevier, 2012-12-24)
Previous experimental studies have determined local strain fields for both healthy and degenerate cartilage tissue during mechanical loading. However, the biomechanical response of chondrocytes in situ, in particular the ...
Modelling the degradation and elastic properties of poly(lactic-co-glycolic acid) films and regular open -cell tissue engineering scaffolds
(Elsevier, 2015-09-02)
Scaffolding plays a critical rule in tissue engineering and an appropriate degradation rate and sufficient mechanical integrity are required during degradation and healing of tissue. This paper presents a computational ...
Cellular contractility and substrate elasticity: a numerical investigation of the actin cytoskeleton and cell adhesion
(Springer Verlag, 2013-06-18)
Numerous experimental studies have established that cells can sense the stiffness of underlying substrates and have quantified the effect of substrate stiffness on stress fibre formation, focal adhesion area, cell traction, ...
Evaluation of a multiscale modelling methodology to predict the mechanical properties of PCL/β-TCP sintered scaffold materials
(Springer Verlag, 2014-12-02)
A multiscale modelling methodology to predict the macroscale stiffness of selective laser sintered polycaprolactone (PCL)/β-tricalcium phosphate (β-TCP) materials is evaluated. The relationship between a micromechanics-evaluated ...
