In wet foam, molecules are more structured than in liquids but more random than they are in solids. Recently, physics of foam has become a rapidly developing branch in science and engineering. A deeper understanding is crucial for many technological applications of wet foam. Hence, in this article, the basic structure and properties of foam are reviewed based on the literature survey of published research work. Some research works, available in the literature, in which optical probes have been used to study the structure, properties and dynamics of foam. In this article, wet foam is used to study the basic structure and properties of foam for better understanding. Raman Spectroscopy and Diffusing wave Spectroscopy have been used on wet foam to establish its structure and properties are also reported. Finally, in conclusion, recent scientific, technological and commercial applications and future prospects of wet foam are proposed to build impulse on the wet foam science more to enrich our day to day life with the modern concepts of nanofoam technology. Recently, due to rapid increase of nanotechnology, different metallic (Cu, Au, Ni, Pt, Pd etc.) or nonmetallic (C) solvent-assisted nanofoam have modernized the structure, properties of foam science and hence have accelerated its day to day technological applications.
