Abstract:

Surface modification may have important influences on the penetration behavior of nanoscale drug delivery system. In the present study, we mainly focused on whether cell targeting or cell penetration could affect penetration abilities of nanostructuredlipid carriers (NLC). Real-time penetration of folate- or cell penetrating peptide (CPP)-modified NLC was evaluated using a multicellular tumor spheroid (MTS) established by stacking culture method as an in vitro testing platform. The results suggested that CPP modification had a better penetration behavior both on penetration depth and intensity compared with folate-modified NLC at the early stage of penetration process.
