Engineered virus-like particles evolve for superior gene delivery efficiency

Researchers developed a barcoded directed evolution system for engineered virus-like particles (eVLPs), creating a fifth-generation (v5) eVLP with enhanced production, transduction, and gene-editing efficiency. This system could pave the way for improved gene delivery vehicles in therapeutic applications.
