An arrangement of β-cyclodextrin chitosan supported on magnetic graphene oxide and its application for in-vitro drug delivery.

•Creating an efficient drug carrier by modification of MGO with bio-degradable materials like chitosan and β-cyclodextrin.•Convenient nanocomposite separation from aqueous media by using an external magnet.•MGO/β-CD-CS carrier can manage well the absorption and in-vitro release of the Omeprazole medicine.•The composite safety was assured using an MTT assay.•The MGO/β-CD-CS nanocomposite is a stable composite and can be recovered easily.
