Summary
The photoactivatable nanoCRISPR/Cas9 system is a light-gated CRISPR/Cas9 gene-editing platform built from crRNA, auxiliary photocleavable oligodeoxyribonucleotides complementary to the crRNA, and carbon nanoparticles. In this design, crRNA is immobilized in a blocked state before irradiation, and 365 nm UV exposure photocleaves the auxiliary oligonucleotides to release crRNA and restore Cas9 activity.
Usefulness & Problems
Why this is useful
This system provides optical control over CRISPR/Cas9 activity by suppressing guide function before illumination and reactivating it after light exposure. It is useful for applications requiring externally triggered gene-editing activation, with tuning enabled through oligonucleotide design, irradiation conditions, and nanoparticle choice.
Problem solved
It addresses the problem of keeping Cas9 inactive until a defined light stimulus is applied. Specifically, it solves this by reversibly immobilizing crRNA on carbon nanoparticles through complementary photocleavable oligodeoxyribonucleotides and releasing the crRNA after 365 nm irradiation.

The construct uses crRNA, photocleavable oligodeoxyribonucleotides complementary to the crRNA, and carbon nanoparticles. Practical performance depends on blocking oligonucleotide length, number of photocleavable linkers, irradiation time, and nanoparticle type; among the tested variants, carbon-encapsulated iron nanoparticles were reported as the most promising.
The supplied evidence is limited to a single source and does not provide detailed quantitative editing outcomes, organismal scope, or independent replication. The system requires 365 nm UV irradiation, and the available evidence does not describe broader validation across targets, cell types, or in vivo settings.

Here, we proposed a new approach to engineering a photoactivatable CRISPR/Cas9 gene-editing system. The novel nanoCRISPR/Cas9 system is based on the use of auxiliary photocleavable oligodeoxyribonucleotides (PC-DNAs) complementary to crRNA.

We optimized the length of blocking photocleavable oligonucleotide, number of linkers, time of irradiation, and the type of carbon nanoparticles. Based on the results, we consider the nanoCRISPR/Cas9 system involving carbon-encapsulated iron nanoparticles the most promising. It provides the greatest difference of functional activity before/after irradiation
photoactivatable nanoCRISPR/Cas9 system and near-infrared light activatable chemically induced split-Cas9/dCas9 system address a similar problem space because they share editing.
