Preformed Liposomes
Plain liposomes are usually used as controls or for loading lipophilic compounds. Liposomes with drug loading battery inside (e.g. ammonium gradient) are ready for loading weakly basic compounds. Cationic liposomes are used for preparing lipoplex for plasmid DNA, oligos and/or siRNA. Liposome with special functionality, such as fluorescent and magnetic liposomes are also frequently used in research.
Empty liposomes
Empty plain liposomes are normally prepared from bilayer-forming phosphatidylcholines with/without cholesterol and PEG-lipids.
Drug loaded liposomes
Doxorubicin HCl loaded into STEALTH liposomes by the ammonium gradient technology.
Lipoplexes (cationic liposome/DNA complexes)
Depending on the method and conditions used the final lipoplex products could be large aggregates or much smaller and more 
liposome-like structure.

The distribution of liposomes in the body (left two pictures) can be imaged by gamma scintigram of radio-active liposomes, such as 111In-DTPA-liposomes. Fluorescent liposomes (right picture) can be used for cell uptake studied. Various types of markers are available for liposomes studies.
