Try slightly positive Z potential (or charge), it diffuse easier through negative EM. We also work on nanoparticles with chyaluronaze, they cutout their way in the forest of EM.

Hi,

We use polymer particles wich have 96-98 % transfection efficiency index.

Try Active PEGylated liposomal delivery of miRNA. They might help you enter the fortress.

We use electroporation and for us it works very good.
