Despite DSBs, they have also been explored through epigenome editing and biosensor applications. However, its in vivo delivery is still a major challenge. Interestingly, ample nonviral nanocarriers have been developed and explored for the in vivo delivery of CRISPR components, but they are limited to some immune-prone organs of the body, such as the liver, lungs, or spleen.
However, various pharmaceutical companies are showing interest in the CRISPR therapeutics area, and therefore, it will be interesting to watch the progress in this field. Since both ethical and social implications are associated with the usage of CRISPR, we need to move forward very responsibly.
