Scientists just made CRISPR three times more effective

• CRISPR gene-editing machinery could transform medicine but is difficult to get into tissues and disease-relevant cells • Particles entered cells three times more effectively, tripled gene-editing efficiency, and decreased toxicity compared to current delivery methods With the power to rewrite the genetic code underlying countless diseases, CRISPR holds immense promise to revolutionize medicine. But until scientists can deliver its gene-editing machinery safely and efficiently into relevant cells and tissues, that promise will remain out of reach. Now, Northwestern University chemists have unveiled a new type of nanostructure that dramatically...
