 In this study, researchers developed a new type of nanoparticle called NH2SSNs, which have positive charges on their surfaces and can deliver nucleic acids into cells, without being destroyed by the body's immune system. This makes them ideal candidates for gene therapies, as they can be stored and transported easily, and modified quickly and efficiently.
