SP-hMNP-COOH

Carboxyl-bearing hollow Fe3O4 magnetic nanoparticle

Sales will begin soon

A hollow iron oxide platform created by selectively removing the Ag core. Supports research on drug loading, bioconjugation, alginate/hydrogel encapsulation, and magnetic recovery. Removing the Ag core minimizes concerns about silver-related cytotoxicity.
