Live bio-nano-sonosensitizer targets malignant tumors in synergistic therapy

Acta Biomaterialia, 2023
Sonosensitizers that can increase the concentration of reactive oxygen species (ROS) within a tumor microenvironment is a high priority for sonodynamic therapy (SDT). In this study, a functionalized, smart nanosonosensitizer based on Au-RuO2 nanoparticles (NPs) and selenium nanoparticles (Se NPs) that were electrostatically self-assembled onto the ...

[Sonosensitizing Action of Teraphtal in Bacterial Media].

Biofizika, 2015
Employing bacterial model systems it was shown that the introduction of the soluble compound--sodium salt of cobalt octacarboxyphthalocyanine (teraphtal)--into the medium led in an ultrasonic field to a decrease in the proportion of survived bacteria.

Mitochondria-targeting sonosensitizer-loaded extracellular vesicles for chemo-sonodynamic therapy

Journal of Controlled Release, 2023
Sonodynamic therapy (SDT) has emerged as an effective therapeutic modality as it employs ultrasound (US) to eradicate deep-seated tumors noninvasively. However, the therapeutic efficacy of SDT in clinical settings remains limited owing to the low aqueous stability and poor pharmacokinetic properties of sonosensitizers.

Ultrasound-dependent cytoplasmic internalization of a peptide-sonosensitizer conjugate

Bioorganic & Medicinal Chemistry, 2017
A method to induce cytoplasmic peptide delivery, using ultrasound, was demonstrated using a molecular conjugate of a cell-penetrating peptide (CPP), a functional peptide, and a sonosensitizer. As a model of such molecular conjugates, TatBim-RB, consisting of the Tat CPP, the Bim apoptosis inducing peptide, and the sonosensitizer rose bengal was ...

Immunosonodynamic Therapy Designed with Activatable Sonosensitizer and Immune Stimulant Imiquimod

ACS Nano, 2022
Sonodynamic therapy (SDT) has garnered extensive attention as a noninvasive treatment for deep tumors. Furthermore, imiquimod (R837), an FDA-approved toll-like receptor 7 agonist, is commonly used in clinical settings as an immune adjuvant. We prepared an activatable sonodynamic sensitizer platform (MR) based on glutathione-sensitive disulfide bonds ...

A sonosensitive diphenylalanine-based broad-spectrum antimicrobial peptide

Nature Biomedical Engineering
The antimicrobial effect of antimicrobial peptides is typically slow; they can be rapidly biodegraded and often have non-selective toxicity and elaborate sequences. Here we report a short peptide that is activated by ultrasound, that shows high broad-spectrum antibacterial efficiency (>99%) against clinically isolated methicillin-resistant bacteria ...

Engineering Sonosensitizer‐Derived Nanotheranostics for Augmented Sonodynamic Therapy

Small
AbstractSonodynamic therapy (SDT), featuring noninvasive, deeper penetration, low cost, and repeatability, is a promising therapy approach for deep‐seated tumors. However, the general or only utilization of SDT shows low efficiency and unsatisfactory treatment outcomes due to the complicated tumor microenvironment (TME) and SDT process.

Multifunctional Porphyrin‐Based Sonosensitizers for Sonodynamic Therapy

Advanced Functional Materials
AbstractSonodynamic therapy (SDT), as a promising non‐invasive therapeutic modality combining ultrasound (US) and sonosensitizers to produce cytotoxic reactive oxygen species (ROS) for treating deep‐seated tumors, has received increasing attention in recent years.

Sonosensitizers for Sonodynamic Therapy: Current Progress and Future Perspectives

Ultrasound in Medicine & Biology
Sonodynamic therapy (SDT) is a novel non-invasive treatment method that combines low-intensity ultrasound and sonosensitizers. Compared with photodynamic therapy, SDT has the advantages of deeper tissue penetration, higher accuracy and fewer adverse reactions. Sonosensitizers are essential for the efficacy of SDT. Sonosensitizers have the advantages of

Tumor growth inhibition by sonodynamic therapy using a novel sonosensitizer

Free Radical Biology and Medicine, 2012
Sonodynamic therapy (SDT) with low-intensity ultrasound combined with a sonosensitizer may be a promising approach to cancer therapy. Use of ultrasound has the advantage of being noninvasive, with deep-penetration properties, and convenient because of the low or no sensitivity of sonosensitizers to light. In this study, SDT with a novel sonosensitizer (
