In this study, we demonstrated that nano-AE can be produced
by reverse evaporation, with spherical morphology,
and of which had a maximum absorption wavelength at
430 nm. Besides, nano-AE maintained its photosensitive
property. The killing effect of nano-AE-mediated r-caspase-3
gene transfection and PDT on the gastric cancer cells was
clear. Inducing the apoptosis and necrosis of gastric cancer
cells may be the main mechanism, but further studies are
warranted to identify concrete pathways.
