Figure Effect of the interaction of SNPs-30 and SNPs-30@BSA with DOPC GUVs. GUVs are labelled with Rh-DOPE (magenta) or DiO (green). a) Time series of GUVs undergoing full membrane fusion after interacting with 25 µg/ml SNPs-30.b) DOPC GUVs before and after incubation with SNPs-30@BSA for 30 min. After incubation with SNPs-30@BSA, the GUVs weakly adhere into clusters but maintain their integrity and do not fuse. On the right, zoomed in image of the region delimited by the yellow box showing each imaging channel (Rh-DOPE and DiO) separately. There is no colocalisation of dyes in the same membrane, indicating the absence of lipid mixing between GUVs labelled with different probes.
