From: Rapid endosomal escape of prickly nanodiamonds: implications for gene delivery

Demonstration of prickly nanodiamonds as vehicles for gene delivery in vitro.
(a) Schematic illustration of the in vitro experimental design for gene delivery using nanodiamonds as carrier. (b–e) typical confocal images of GFP expression in HepG2 cells after cells’ being treated with (b) fresh medium, (c) free DNA, (d) SiO2-DNA and (e) NDs-DNA.
