Abstract

Nanobubbles, particularly bulk nanobubbles, are gas-filled cavities suspended within a liquid. Recently, bulk nanobubbles have garnered significant interest due to their distinctive nanoscale physical properties. While traditional gas diffusion theories and Laplace pressure suggest that nanobubbles should dissolve within a few microseconds, experimental observations have shown that they can persist in solution for hours or even days. This exceptional stability and extended lifespan have made bulk nanobubbles a focal point for numerous research groups globally. In this paper, we explore the historical development of research on bulk nanobubbles, examine their characteristics along with current techniques for their generation and detection, and assess the validity of stability theories related to bulk nanobubbles. Additionally, we highlight key applications of bulk nanobubbles across various fields.
