FTIR confirmed the presence of functional groups associated with sodium alginate, polyethyleneimine, and UiO-66-NH 2. XRD showed characteristic peaks of UiO-66-NH 2, indicating their retention within ...

A temperature-sensitive hydrogel embedded with sodium alginate (SA)-chitosan (CS) microspheres was constructed for colon-targeted delivery of SZ-A. The results showed that the microspheres ...
