Key Nanotechnologie For Targeted Therapy

Liposomal Nanopaterles

Liposomes are sferycal vesicles composted of lipid bilayers that can encapsulate both hydrophilic and hydrophobic drugs. They were among the first nanocarriers to receive FDA approval for cancer treatment. Liposomal formulations such as incore 1; FLT: 0 metribul 3; Doxil entreme 1; FLT: 1 metribulion tulion tumorin; (pegylated liposal doxorubicin) improwize drug cipation tion time diculite cardiculitoxic whwe whilvely aculatinn tuorthorthalthalg.

Polymeric Nanopactartles

Polimers such as PLGA (poly (lactic- co- glikolic acid) and PEG are widely used to create biodegradable nanopaterles. These systems allow consumed of chemotherapeutics, proteins, or nuclec acids. Polymeric nanopaterles can be designed for active activite docuing by concompagating antibodies or peptides tich their surface.
