Cryogel composites based on hyaluronic acid and halloysite nanotubes as scaffold for tissue engineering

We present here preparation of mechanically strong and biocompatible cryogel composites based on hyaluronic acid (HA) and halloysite nanotubes (HNTs) of various compositions, and their applications as scaffold for different cell growing media. Uniaxial compression tests reveal that the incorporation of HNTs into HA cryogels leads to a ~2.5-fold increase in their Young moduli, e.g., from 38 ± 1 to 99 ± 4 kPa at a HA:HNTs weight ratio of 1:2....
