Types of DNAzyme delivery systems and the outcomes.
| Delivery systems | Outcomes | References |
| Biodegradable poly(D, L-lactide-co-glycoid) copolymer (PLGA) microspheres | Efficient and sustained delivery | [146] | Cyclodextrin-containing polycation (CDP) | A rapid and efficient intracellular uptake into various cell lines | [147] | Branched polyethylenimine | Higher biocompatibility and efficient transfection. Less cytotoxicity and promote gene dissociation | [148] | N-Acetyl-L-leucine-polyethylenimine (N-Ac-L-Leu-PEI) | Efficient cellular uptake and exhibited protective function against nucleases | [79] | Dendrimers | Low toxicity, higher water solubility, and increased stability against hydrolysis | [149] | Modified fourth-generation dendrimers termed G4 (MeI) | Efficient DNAzyme delivery without substantial toxicity | [149] | Colloidal gold nanoparticles | Less toxic and an efficient DNAzyme transfection | [150] | Liposomes | Efficient targeted delivery | [151ā153] | Chitosan nanoparticles | Effective cellular uptake ability, remain stable at room temperature for a month and for seven days in serum without a substantial loss in activity | [154ā156] | Toxic side effects such as myelosuppression, alopecia, and hepatic toxicity can be associated | [157] |
