    Abstract: Liposomes are self-assembled structures that contain an inner aqueous compartment surrounded by a lipid bilayer. This unique structure inherently provides liposomes with a powerful capability for encapsulating hydrophilic, hydrophobic or amphiphilic molecules or nanoparticles. Combining this property with appropriate signal amplification strategies... Show More
