Microfluidic production of hyaluronic acid derivative microfibers to control drug release
| Resumo: | Microfibers of a hyaluronic acid amphiphilic derivative (HA-EDA-C18), with incorporated dexamethasone (Dex) as a model bioactive molecule, were obtained by microfluidic technique. Exploiting the ionic strength sensible behavior of HA-EDA-C18, microfibers were formed in baths containing phosphate buffer saline with different salt concentration.
