The invention provides a method of preparing a microbubble covalently attached to at least one therapeutic agent which comprises: (i) providing a lipid (e.g. a phospholipid) capable of forming a microbubble; covalently linking at least one therapeutic agent to said lipid to produce a functionalised lipid; and preparing a microbubble from said functionalised lipid. Microbubble-therapeutic agent complexes which comprise a microbubble shell formed from a plurality of lipids (e.g. phospholipids) in which at least a proportion of the lipids are covalently linked to at least one therapeutic agent are also provided. Examples of therapeutic agents which may be attached to the microbubble include chemotherapeutic agents and sonosensitising agents. The complexes find use in methods of sonodynamic therapy and, in particular, in methods of combined sonodynamic therapy and chemotherapy.

A Rose Bengal sonosensitiser has been covalently attached to a lipid microbubble and the resulting conjugate shown to produce higher levels of singlet oxygen, enhanced cytotoxicity in a cancer cell line and a greater reduction in tumour growth than the sonosensitiser alone.
