In the design of tissue engineering scaffolds, design parameters including pore size, shape and interconnectivity, mechanical properties and transport properties should be optimized to maximize successful inducement of bone ingrowth.
These materials should have adequate porosity, appropriate pore size, interconnectivity, and mechanical behavior compatible with the features of native tissue, allowing cell activities.
It is shown that the pore dimension, interconnectivity and mechanical properties in compression of the scaffold could be predefined by an appropriate choice of the size of the protein-free microparticles and process conditions.
The porous HA/PCL composite scaffolds dip-coated with 10% PCL exhibited optimal combination of mechanical properties and pore interconnectivity, and may be a potential bone candidate for the tissue engineering applications.
This means that the other 80% must be given by the combined effects of mechanical properties, morphology and interconnectivity of the rigid phases.
Scaffolds that possess adequate biodegradability, pore size, interconnectivity, bioactivity and mechanical properties in accordance with the injured tissue are required.
The prepared scaffold possessed high porosity of 92.38 ± 5.12% and pore size of 165.00 ± 8.25 μm as well as high pore interconnectivity and appropriate mechanical properties.
Porous hydrogel structures with a gyroid pore network architecture showed narrow pore size distributions, excellent pore interconnectivity and good mechanical properties.
We obtained poly l-lactic acid) (poly l-lacticds with elevacid PLLAscaffolds%) and interconnectivity, with good melevatedl porosityes (compressive modulus up to 81 kPa).
The morphology characterization of complex structures is a demanding but fundamental task, as the morphological properties, such as porosity, pore size, pore wall size, and interconnectivity, affect the mechanical behavior as well as the biological performances of the scaffolds.
