Table 1: An overview of the morphological characteristics of different types of liposomes [5].

Multilamellar vesiclesConsist of several concentric bilayers. Range in size from 500 to 5000 nm. Ideal for trapping hydrophobic drugs in additional lamellae

Large unilamellar vesiclesConsist of one concentric lipid bilayer surrounding a large inner aqueous environment. Range in size from 200 to 800 nm. Ideal for trapping large amounts of hydrophilic drugs

Small unilamellar vesiclesConsist of one concentric bilayer. Small size in the range of 100 nm. Ideal for long-term circulation.
