Soft matter is a branch of physics and materials science that focuses on the study of materials that are neither liquid nor solid in the traditional sense. Soft matter encompasses a wide range of materials, including colloids, polymers, liquid crystals, and biological tissues. These materials exhibit unique physical properties and behaviors that are intermediate between those of liquids and solids, such as viscoelasticity, self-assembly, and responsiveness to external stimuli. Research in soft matter often involves the study of the structure, dynamics, and properties of these materials, as well as the development of new materials with novel functions and applications. Soft matter research has applications in a variety of fields, including materials science, biophysics, and nanotechnology.
