Nonviral Gold Nanoparticle‐Mediated Delivery of CRISPR‐Cas9 Ribonucleoprotein and Long DNA Transgenes Into Primary Blood Cells

Advanced NanoBiomed Research, EarlyView.
CRISPR/Cas9 has revolutionized the field of gene therapy, but delivery remains an outstanding issue. We propose a nonviral gold‐nanoparticle platform for co‐delivery of CRISPR/Cas9 ribonucleoprotein and long 2.1 kilobase dsDNA transgene constructs. This CRISPR‐AuNP is inexpensive to produce and mediate gene editing and DNA delivery in T cells and CD34+
