Our research focuses on the design and application of Biocolloids. Biocolloids are particles less than ten microns in diameter comprised of biological molecules, such as lipids, proteins and polymers. Examples include microbubbles, vesicles, micelles, microemulsions and nanoparticles. Biocolloids are often used in biomedical applications as imaging contrast agents and drug delivery vehicles. Our group is very interested in microbubbles, which are stabilized gas particles of less than 10 microns in diameter (roughly the size of a red blood cell). They may be used for ultrasound imaging, targeted drug delivery and metabolic gas delivery. We are investigating both the underlying physicochemical properties and biomedical performance of microbubbles. Our approach is to gain a better understanding of microbubbles through colloid science methods and to use this knowledge to engineer new constructs to expand their biomedical potential.
