Amphiphilic copolymers are unique molecules that contain both hydrophilic (water-attracting) and hydrophobic (water-repelling) segments. This dual nature allows them to interact with both water and oil, making them useful in various applications, such as drug delivery, emulsification, and surface modification. These copolymers can self-assemble into structures like micelles or vesicles in solution, which can encapsulate drugs or other substances. Their ability to form stable structures in different environments makes them valuable in fields like biotechnology and materials science.
