제목 Microbubble-Self-Aggregate Complex Applied for Ultrasound-Mediated Enhanced Targeted Imaging and Drug Delivery
초록 Microbubbles can be applied to a bifunctional material, such as drug delivery carrier and ultrasound contrast agent. Microbubble delivers the drug by conjugation of drug delivery carriers seems like nanoparticles or liposome. Under the acute ultrasound condition, the microbubble proceeds to collapse and release conjugated nanoparticles. After the microbubble is collapsed, induced strong mechanical stress can occur at the site of the blood vessel and increased permeability. It is called ‘microjet’. As using this technique, we can control drug release at the target area by the selective exposition of ultrasound. In this study, a self-assembled nanostructure loaded hydrophobic drug was chemically conjugated to microbubble. The conjugation ratio of microbubble and micelle was examined by UV-Vis spectroscopy. And the size distribution of microbubble and self-assembled nanostructure were analyzed by dynamic laser scattering(DLS).
