7.1 Introduction

Bioscaffolds are artificial structural materials which can potentially be used to promote tissue regeneration and injury recovery after their implantation into the human body by various methods. The ideal scaffolds should demonstrate certain characteristic features such as:

  1. They should be highly biocompatible to support the cell adhesion, proliferation, differentiation, and migration.
  2. They should possess a fine three‐dimensional (3D) structure. The fine 3D structure of scaffolds has a good influence on the cell activity and growth of tissues. The fine 3D structure of the scaffold is achieved through special process technology by controlling the specific parameters, such as surface properties, geometry, and porosity, etc.
  3. Different tissues have different mechanical properties, thus the scaffold used for the regeneration of new tissues must possess the appropriate mechanical features and be degraded at a suitable rate compared to the host tissues.
  4. The scaffold should direct and control the behavior of the cells and tissues during the interaction between the host cells.
  5. The ...
