Bioactive glasses are widely used in bone tissue
engineering (BTE) since they can develop strong bonds
with bone through the formation of a hydroxyapatite
(HA) layer1. Within these materials, sol-gel-based
bioactive glasses (SGBGs) are attractive due to their
enhanced bioactivity and resorbability and their
capacity of being functionalised with a large variety of
moieties2-3.
Surface functionalisation is an interesting approach to
load drugs into the material and allow their release in a
controlled manner3.
The aim of this study is the development of new
SGBGs for 3D porous scaffolds and functionalisation of
their surface by two different methods4-5 in order to
enhance the drug delivery capability
