A Systematic Study on Long-acting Nanobubbles: Current Advancement and Prospects on Theranostic Properties

Delivery of diagnostic drugs via nanobubbles has shown to be an emerging field of study. Due to their small size, nanobubbles may more easily travel through constricted blood vessels and precisely target certain bodily parts. Nanobubble is considered the major treatment for cancer treatment and other diseases which are difficult to diagnose. The field of nanobubbles is dynamic and continues to grow as researchers discover new properties and seek practical applications in various fields. The predominant usage of nanobubbles in novel drug delivery is to enhance the bioavailability, and controlled drug release along with imaging properties Nanobubbles are important because they may change interfacial characteristics including surface force, lubrication, and absorption. The quick diffusion of gas into the water was caused by a hypothetical film that was stimulated and punctured by a strong acting force at the gas/water contact of the bubble. In this article, various prominent aspects of nanobubbles have been discussed, along with the long-acting nature, and the theranostical aspect which elucidates the potential marketed drugs along with clinical trial products. The article also covers quality by design aspects, different production techniques that enable method-specific therapeutic applications, increasing the floating time of the bubble, and refining its properties to enhance the prepared nanobubble's quality. Nanobubble containing both analysis and curing properties makes it special from other nano-carriers. This work includes all the possible methods of preparing nanobubble, its application, all marketed drugs, and products in clinical trials.
