Research output: Contribution to journalConference articlepeer-review


We have developed a new synthesis of proteinaceous microcapsules at high concentrations with narrow size distributions. High-intensity ultrasound is used both to emulsify and to chemically crosslink protein molecules. The chemical crosslinking is responsible for the permanence of the microcapsules and consists principally of intermolecular disulfide bonds formed by cysteine oxidation from sonochemically-generated superoxide. Proteinaceous microcapsules of bovine serum albumin (BSA) filled with dodecane, decane, cyclohexane, or toluene have been synthesized.
