Ultrasound microbubbles can serve as cavitation nuclei for targeted drug and gene delivery. By incorporating therapeutics into these agents, ultrasound energy triggers localized release, enhancing treatment efficacy.

Area of Science:

  • Biomedical Engineering
  • Acoustic Medicine
  • Nanotechnology

Context:

  • Ultrasound microbubbles are known to lower the cavitation threshold.
  • Cavitation is a key phenomenon in ultrasound-mediated therapies.
  • Current drug and gene delivery methods face challenges in targeted delivery and efficacy.

Purpose:

  • To explore the use of ultrasound microbubbles as cavitation nuclei for enhanced drug and gene delivery.
  • To investigate the incorporation of therapeutic agents into ultrasound contrast agents.
  • To demonstrate localized release of therapeutic agents via ultrasound-induced microbubble cavitation.

Summary:

  • Ultrasound microbubbles can function as cavitation nuclei, facilitating targeted drug and gene delivery.
  • Tailoring microbubble physical properties and coating materials allows for the incorporation of drugs and genetic materials.
