Figure 2From: In vitro performance of lipid-PLGA hybrid nanoparticles as an antigen delivery system: lipid composition mattersConfocal images of LPK NPs. The images illustrate that KLH was labeled with rhodamine B (red) and liposome was labeled with NBD (green), confirming that PK NPs were enclosed by liposome. Scale bars represent 10 μm.Back to article page
