Cell mechanics and cell-materials interactions are important for disease diagnosis and tissue engineering.
The synergistic combinationof computational modelling and experimental approaches allows exploring phenomena
in cell mechanics and mechanotransduction that are not easily accessible with experimental methods alone.
A hybrid modelling anomechanical testing approach enables determining the viscoelastic properties of the living
cells, which is useful to quantify the biomechanical effects of drug treatment, diseases and aging [1-2].
Such a nano-biomechanical technique can also be applied to assess the micro(nano)scale mechanical
properties of engineered bone [3], extracellular matrix [4-5] and scaffold materials [6] which could further the
understanding cell-materials interactions. In addition, this presentation will cover how cells respond to two-dimensional and three-dimensional micromechanical environment [7-9], which will help a better understanding
of the mechanotransduction and provide valuable guide for optimising scaffold design and cell manipulations
for desired tissue engineering.
