7 Silver nanoparticles boost DNA assembly efficiency fivefold in Japanese breakthrough¶
Japanese researchers at Nagoya and Gifu universities developed a method using PEG-coated silver nanoparticles to cut and assemble DNA with two to five times greater efficiency than conventional restriction enzymes. The technique, published in Nucleic Acids Research, could accelerate construction of large DNA sequences for gene therapies, cancer vaccines, and engineered crops.
- Silver nanoparticles coated with polyethylene glycol (PEG) slice DNA and create longer sticky ends
- DNA cleavage efficiency reached ~50% at 70°C and nearly 100% at 95°C within two hours
- Two to five times higher efficiency than conventional restriction enzyme methods
- Applications include gene therapies, cancer vaccines, and engineered drugs
