Microbubbles are versatile ultrasound contrast agents with therapeutic potential. Ultrasound-activated microbubble cavitation can dissolve blood clots and deliver drugs or genes with targeted precision.

Area of Science:

  • Biomedical Engineering
  • Ultrasound Technology
  • Nanomedicine

Background:

  • Microbubbles are established ultrasound contrast agents.
  • Microbubble cavitation induced by ultrasound has therapeutic potential.
  • Targeted microbubbles offer precise diagnostic and therapeutic capabilities.

Purpose of the Study:

  • To review the therapeutic applications of microbubbles.
  • To discuss experimental results of microbubble-mediated treatments.
  • To explore targeted drug and gene delivery using ultrasound-activated microbubbles.

Main Methods:

  • Review of experimental studies on microbubble applications.
  • Analysis of microbubble cavitation mechanisms.
  • Incorporation of targeting ligands and drugs into microbubbles.
