CRISPR/Cas9 Fitted with Ultrasound-Powered Propeller

A new system that transports gene-editing tools into cells may leave other such systems in its wake. The new system, developed by American and Danish scientists, uses an ultrasound-powered nanopropeller. Instead of blades, the nanopropeller has an asymmetrically shaped gold nanowire that it churns through the fluid mosaic of the cell’s plasma membrane. Once inside the cell, the nanopropeller falls apart and frees its cargo: a gene-editing complex consisting of the CRISPR -associated protei
