Gene therapy is a new kind of medicine, which uses genes as drugs in order to treat life threatening diseases. In the present work, a nonviral vector, aminated β-cyclodextrin-modified-carboxylated magnetic cobalt-nanocellulose composite ACDC-Co-NCC, was synthesized for efficient transfection of genes into tumour cells. The synthesized ACDC-Co-NCC was characterized by means of FTIR, XRD, SEM, and ESR techniques. DNA condensing ability of ACDC-Co-NCC was found to be increased with increase in amount of ACDC-Co-NCC and 84.9% of DNA 1.0 μg-mL inclusion was observed with 6.0 μg-mL of ACDC-Co-NCC. The cytotoxicity of ACDC-Co-NCC was observed to be minimal, even at higher concentration, with respect to the model transfecting agent, polyethyleneimine PEI. 88.2% of the gene was transfected at high dose of DNA, as indicated by the highest luciferase expression. These results indicated that ACDC-Co-NCC might be a promising candidate for gene delivery with the characteristics of good biocompatibility, potential biodegradability, minimal cytotoxicity, and relatively high gene transfection efficiency.
