Research Interest
Engineering microbubbles for biomedical applications: Microbubbles are colloidal particles with 0.1 to 10 μm diameter and consist of a shell made of lipid or protein molecules. The shell encapsulates a gaseous core containing gases such as Perfluorobutane (PFB), Sulphur Hexafluoride (SF6) or Oxygen (O2). The microbubble shell can contract and expand upon exposure to ultrasound. This phenomenon enables the use of microbubbles in applications such as contrast imaging, sonoporation and as drug/gene delivery vehicles. Our research efforts are focused on synthesis of microbubbles and understanding the effect of shell material, additives, storage medium and transport properties of core gas on the stability and biocompatibility of aqueous microbubble suspensions.
