Nanoblade-Based Delivery of Nucleic Acid Cargo: A Technique to Deliver Cas9-sgRNA Complex to Target Cells via Virus-Like Particles

Executive Industry Relevance

Nanoblade-based delivery enables precise, dose-dependent transport of Cas9-sgRNA ribonucleoprotein complexes into target cells, supporting rapid and scalable genome editing workflows. As synthetic virus-like particles devoid of replicative capacity, nanoblades offer a safer alternative to viral vectors for preclinical target validation and mechanistic de-risking in early discovery. This approach enhances predictive confidence in therapeutic hypothesis testing by facilitating efficient cargo delivery without genomic integration risks.
