“…Under a magnetic field, cells were incubated with a vector‐magnetic particle mixture that attracted the particles into the cells 82 . The magnetic particles used were mainly superparamagnetic iron oxide nanoparticles, which were coated with highly biocompatible polymers, such as PEI, 83 glucan, 84 and poly(amidoamine) (PAMAM) dendritic macromolecules 85 . The results of magnetic transfection comprise the rapid deposition of a full‐dose vehicle on target cells, which further leads to a high percentage of cells being rapidly transfected within minutes 86 …”

Gene therapy, a medical approach that involves the correction or replacement of defective and abnormal genes, plays an essential role in the treatment of complex and refractory diseases, such as hereditary diseases, cancer, and rheumatic immune diseases. Nucleic acids alone do not easily enter the target cells due to their easy degradation in vivo and the structure of the target cell membranes. The introduction of genes into biological cells is often dependent on gene delivery vectors, such as adenoviral vectors, which are commonly used in gene therapy. However, traditional viral vectors have strong immunogenicity while also presenting a potential infection risk. Recently, biomaterials have attracted attention for use as efficient gene delivery vehicles, because they can avoid the drawbacks associated with viral vectors. Biomaterials can improve the biological stability of nucleic acids and the efficiency of intracellular gene delivery. This review is focused on biomaterial‐based delivery systems in gene therapy and disease treatment. Herein, we review the recent developments and modalities of gene therapy. Additionally, we discuss nucleic acid delivery strategies, with a focus on biomaterial‐based gene delivery systems. Furthermore, the current applications of biomaterial‐based gene therapy are summarized.

“…Also, the chemically synthesized siRNAs are easily modified by chemicals. However, extensive and complicated modifications to siRNAs can lead to higher production costs [ 23 , 26 ]. In addition, as its RNA is chemically synthesized, it is easier to degrade and has a shorter action time.…”
