Abstract	Ultrasound has long been recognized as a means of effecting change at the cellular and tissue levels [1–3], which may be enhanced in the presence of photosensitive agents [4–6]. During insonation, the presence of bubbles can also play a role, creating strong microstreaming effects in solution and in more dramatic circumstances leading to the formation of energetic microjets [7], plasmas [8], and the production of other highly reactive species [9]. Such ‘sonodynamic activity’ has generated particular excitement in the medical community as it Moreover the dual role for microbubbles as both an adjunct to therapy and a diagnostic echogenicity enhancer has seen industry take a proactive role in their development. In the present paper we studied the role of ultrasound driven sonoluminescent light on the degradation of a fluorescent test species (rhodamine) in the presence of an archetypal photocatalyst material, TiO2, with a view to exploring its exploitation potential for downstream medical applications. We found that, whilst the efficiency of this process is seen to be low compared with conventional ultra-violet sources, we advocate the further exploration of the sonoluminescent approach given its potential for non-invasive applications. A strategy for enhancing the effect is also suggested.
