Active Delivery of CRISPR System Using Targetable or Controllable Nanocarriers.

Area of Science:

• Biotechnology
• Nanomedicine
• Gene Therapy

Background:

• Clustered regularly interspaced short palindromic repeats (CRISPR) technology offers promising genome editing capabilities for gene therapy.
• Effective delivery systems are essential for the clinical application of CRISPR technology.
• Current nanocarrier delivery systems require improved targeting and controllability to minimize side effects and off-target gene editing.

Purpose of the Study:

• To summarize targetable and controllable nanocarriers for CRISPR system delivery.
• To review cell or organ-selective nanocarriers.
• To discuss nanocarriers controlled by biochemical or physical signals.

Main Methods:

• Literature review of nanocarrier-mediated CRISPR delivery systems.
• Categorization of nanocarriers based on targeting strategies (cell/organ selective).
• Analysis of control mechanisms (biochemical/physical signals).

Main Results:

• Nanocarriers offer safer and cheaper alternatives to physical and viral delivery methods for CRISPR.
• Targetable nanocarriers enhance accumulation at disease sites.
• Controllable nanocarriers allow for spatial and temporal resolution in CRISPR delivery.

Conclusions:

• Targetable and controllable nanocarriers are key to advancing CRISPR-based gene therapy.
• Further research is needed to address challenges in existing nanocarrier technologies.
• Optimized nanocarrier design will improve the safety and efficacy of CRISPR genome editing.
