Abstract: Anticancer medications as well as additional therapeutic compounds, have poor clinical
effectiveness due to their diverse distribution, non-selectivity for malignant cells, and undesirable
off-target side effects. As a result, ultrasound-based targeted delivery of therapeutic compounds
carried in sophisticated nanocarriers has grown in favor of cancer therapy and control.
Nanobubbles are nanoscale bubbles that exhibit unique physiochemical properties in both their
inner core and outer shell. Manufacturing nanobubbles primarily aims to enhance therapeutic
agents' bioavailability, stability, and targeted delivery. The small size of nanobubbles allows for
their extravasation from blood vessels into surrounding tissues and site-specific release through
ultrasound targeting. Ultrasound technology is widely utilized for therapy due to its speed, safety,
and cost-effectiveness, and micro/nanobubbles, as ultrasound contrast agents, have numerous
potential applications in disease treatment. Thus, combining ultrasound applications with NBs
has recently demonstrated increased localization of anticancer molecules in tumor tissues with
triggered release behavior. Consequently, an effective therapeutic concentration of drugs/genes
is achieved in target tumor tissues with ultimately increased therapeutic efficacy and minimal
side effects on other non-cancerous tissues. This paper provides a brief overview of the production
processes for nanobubbles, along with their key characteristics and potential therapeutic
uses.
