Nanoparticle-Assisted Sonosensitizers and Their Biomedical Applications

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Photodynamic Therapy

Background:

• Sonodynamic therapy (SDT) is a non-invasive treatment that uses ultrasound and sonosensitizers to produce reactive oxygen species (ROS).
• Traditional sonosensitizers have limitations that restrict the clinical use of SDT.
• Nanotechnology offers solutions by developing nanoparticles (NPs) to enhance sonosensitizer performance.

Purpose of the Study:

• To review the mechanisms of SDT.
• To classify nanoparticle-assisted sonosensitizers.
• To discuss the biomedical applications and future prospects of NPs-assisted SDT.

Main Methods:

• Literature review of SDT mechanisms.
• Classification of various NPs-assisted sonosensitizers.
• Discussion of applications in ultrasonography, drug delivery, and combination therapies.

Main Results:

• NPs enhance sonosensitizer efficacy and enable targeted delivery.
• NPs-assisted SDT shows promise in various biomedical applications.
• Challenges and future research directions for NPs-assisted SDT were identified.

Conclusions:

• Nanoparticle-assisted sonosensitizers represent a significant advancement in SDT.
• Further research is needed to overcome current challenges and fully realize the potential of NPs-assisted SDT.
