Liposomal formulations can be categorized based on their composition and functional modifications:
Conventional Liposomes: Simple phospholipid bilayers without surface modifications. PEGylated Liposomes: Surface-modified with polyethylene glycol (PEG) to evade immune detection and prolong circulation time. Targeted Liposomes: Equipped with ligands or antibodies that bind to specific receptors on cancer cells for targeted delivery. Thermosensitive Liposomes: Designed to release their payload in response to external stimuli like temperature.
