The future of genetic medicine hinges on successful intracellular delivery of nucleic acid-based therapeutics. While significant effort has concentrated on developing nano-carriers to improve the delivery aspects, scant attention has been paid to the synthetic process of poorly controlled nanocomplex formation. Proposed here is a reliable system to better control the complexation process, and thus the physical properties of the nanocomplexes, through microfluidics-assisted confinement (MAC) in picoliter droplets. We show that these homogeneous MAC-synthesized nanocomplexes exhibit narrower size distribution, lower cytotoxicity, and higher transfection efficiency compared to their bulk-synthesized counterparts. MAC represents a physical approach to control the energetic self-assembly of polyelectrolytes, thereby complementing the chemical innovations in nano-carrier design to optimize nucleic acid and peptide delivery.
