@Snoeffelen this is super super interesting. in this very recent paper (24 june) Sanofi R&D is saying something spectacular about pci (light triggered endosomal escape ), i think they are referring to moderna trial.
They talking frequently here about light triggered endosomal escape not necessarily mentioning pci biotech as a company but we get the point. I think this is a must read. the technology is getting noticed. the most important thing they forgot to mention is naked delivery.
