Abstract
CRISPR technology is a powerful tool for gene editing, in which the efficient delivery of living target cells allows it to show great clinical potential. At present, the commonly used in vivo delivery strategies mainly include biological methods (AAV, VLP, SEND) and chemical methods (LNP), which subtly deliver gene editors to living target cells safely and efficiently from different ways. However, existing delivery systems have different extents of limitations in terms of editing efficiency, immunogenicity, half-life, etc., so developing optimized delivery systems is the key to fully realizing the potential of CRISPR-Cas system for intracellular gene editing. In order to fully understand the advantages of different delivery strategies to maximize the ability to help CRISPR systems choose delivery methods, we conducted a systematic review. In this paper, we introduce the types, principles and characteristics of gene editing systems in order to understand their requirements for delivery tools. We focus on describing the type, principle, load, immunogenicity, specificity, toxicity, etc. of the delivery system, so as to fully analyse its advantages and disadvantages for the selection of different editing environments. This review aims to provide new insights to facilitate appropriate delivery systems or improve the efficacy of existing systems.
The continued convergence of nanotechnology and genome engineering may support the development of personalized medicine strategies that adapt genetic engineering tools for patient-specific applications, thereby improving the safety and reliability of gene-editing therapies.

Efficient delivery of CRISPR components remains a major determinant of genome editing outcomes. In this study, we compared conventional lipofection with magnetic nanoparticle-assisted gene delivery (magnetofection) for CRISPR-mediated genome editing efficiency using SpCas9 and AsCas12a systems. Based on the average values obtained from multiple independent targets, lipofection resulted in relatively low indel efficiencies, with mean values of average 8.1%–12.47%. In contrast, magnetofection markedly enhanced genome editing outcomes, yielding average indel efficiencies of average 42.29%–45.04%, representing a substantial increase (3.39- and 5.56-fold, respectively) compared with lipofection. This enhancement was consistently observed across both SpCas9-and AsCas12a-mediated editing, indicating that the improved efficiency conferred by magnetic nanoparticle delivery is independent of the nuclease platform. Furthermore, the increased performance of magnetofection was reproducible across multiple genomic loci and cell lines and was also effective under RNP-based delivery conditions, demonstrating its robustness and reliability. In addition to indel-based genome disruption, magnetofection also significantly improved prime editing efficiency (13.95% on average) compared to lipofection (3.81% on average). Overall, our results demonstrate that magnetic nanoparticle-mediated delivery enables highly efficient and reproducible CRISPR genome editing, substantially outperforming conventional lipofection for both indel formation and prime editing. Magnetofection therefore represents a powerful and broadly applicable delivery strategy for next-generation genome editing applications.
A major focus of this review is the inclusion of recent hybrid systems (VLPs, SORT-LNPs) and the recognition that chemical modification of guide RNAs is a critical parameter for therapeutic success and that hybrid systems and stimuli-responsive nanoparticles are poised to dominate the next 5 years of clinical development.
