| Sumario: | CRISPR/Cas9 has revolutionized genome editing by enabling precise and efficient genetic modifications across multiple biological systems. Despite its growing therapeutic potential, key challenges remain in mitigating off-target effects, minimizing immunogenicity, and improving the delivery of CRISPR components into target cells. This review provides an integrated analysis of physical, viral, and non-viral delivery systems, highlighting recent advances in the use of lipid nanoparticles, polymeric carriers, and hybrid platforms. We also examine an often overlooked factor: the aggregation behavior of the Cas9 protein, which may interfere with cellular uptake, the encapsulation efficiency, and nuclear localization. By comparing delivery platforms and their reported editing outcomes, we identify critical physicochemical parameters that influence therapeutic success. Finally, we propose standardized methods to assess Cas9 encapsulation and aggregation and discuss translational barriers such as manufacturing scalability and regulatory requirements. These insights aim to guide the development of safer and more effective CRISPR/Cas9-based therapies |
