Knowing the size, concentration and zeta potential of a liposome preparation can help predict its fate in vivo, while the association of charged liposomes with oppositely charged molecules can be monitored by measuring the zeta potential of the resulting complex.
Plain PEGylated liposomes are composed of a bilayer-forming phospholipid and mPEG-DSPE with or without CHOL.
But a new research from University of Southern Denmark has shown that liposomes are not capable of transporting themselves deep into the skin, and thus they are not capable of transporting active ingredients deep into the skin.
