Delivery Strategy·Research·Since 2021

Also known as: carbon-encapsulated iron nanoparticles

Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.

Summary

Carbon nanoparticles, particularly carbon-encapsulated iron nanoparticles, were developed as a photoactivatable nanoCRISPR/Cas9 delivery harness in which photocleavable oligodeoxyribonucleotides are immobilized on the nanoparticle surface to reversibly block crRNA. UV irradiation at 365 nm cleaves the blocking oligonucleotides, releases crRNA, and restores Cas9 editing activity.

Usefulness & Problems

Why this is useful

This system provides light-gated control over CRISPR/Cas9 activity by keeping crRNA inactive until irradiation. It is useful for applications requiring temporal regulation of genome editing through an externally applied optical trigger.

Problem solved

The tool addresses the problem of preventing Cas9 activity before a desired activation time by sequestering crRNA with complementary photocleavable oligonucleotides on a nanoparticle surface. It thereby enables reversible pre-irradiation suppression and post-irradiation restoration of editing function.

Problem links

Need controllable genome or transcript editing

Derived

Carbon nanoparticles, particularly carbon-encapsulated iron nanoparticles, were used as a photoactivatable nanoCRISPR/Cas9 delivery harness in which photocleavable oligodeoxyribonucleotides are immobilized on the nanoparticle surface to reversibly block crRNA. Upon 365 nm UV irradiation, the blocking oligonucleotides are cleaved, crRNA is released, and Cas9 editing activity is restored.

The construct uses photocleavable oligodeoxyribonucleotides complementary to crRNA, immobilized on carbon nanoparticles via a 3'-terminal pyrene residue. Reported practical optimization variables included blocking oligonucleotide length, linker number, irradiation time, and nanoparticle type, with carbon-encapsulated iron nanoparticles selected as the best-performing version.

The available evidence is limited to a single 2021 source and emphasizes relative before-versus-after irradiation performance rather than broad validation across targets or biological contexts. Activation requires 365 nm UV light, and the supplied evidence does not describe independent replication, in vivo validation, or delivery performance beyond the reported nanoCRISPR/Cas9 formulation.

The authors optimized blocking oligonucleotide length, linker number, irradiation time, and carbon nanoparticle type, and identified the carbon-encapsulated iron nanoparticle version as the most promising because it gave the greatest before-versus-after irradiation functional activity difference.

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

Source-backed strengths

The reported system achieved sufficient blocking of crRNA when photocleavable DNAs were immobilized on carbon nanoparticles through a 3'-terminal pyrene residue. The authors also optimized blocking oligonucleotide length, linker number, irradiation time, and nanoparticle type, and identified carbon-encapsulated iron nanoparticles as the most promising formulation because they produced the largest functional difference before versus after irradiation.

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.
