Development of Microbubble Assisted Ultrasound Mediated Drug Delivery System |
| 초록 |
Microbubbles play a role not only ultrasound contrast agent for use molecular imaging but ultrasound mediated drug delivery carrier. Microbubble able to deliver the drug by conjugation of drug delivery carriers like liposome or nanoparticles. Under the intensive ultrasound, microbubble undergoes collapse and release conjugated nanoparticles. Destruction of microbubble produces strong mechanical stress called microjets, it can partially damage blood vessel so a selective increase of permeability is possible. By using this technique, selective expose of ultrasound to target area make a targeted drug delivery. In this study, hydrophobic drug loaded self-assembled nanostructure was chemically conjugated to microbubble. Microbubble and self-assembled nanostructure size distribution were analyzed with dynamic laser scattering (DLS), conjugation ration of microbubble and micelle were examined by UV-vis spectroscopy. |
