Amphiphilic copolymers have revolutionized the study of membrane proteins (MPs), where MPs are known to be critical targets in pharmaceutical development due to their roles in various physiological processes. Traditionally, MP extraction has relied on detergents, which often compromise the protein integrity. Advancements over the past 15 years include the use of poly(styrene--maleic acid) (SMA) to form nanoscale SMALPs (styrene maleic acid lipid particles), enabling detergent-free MP extraction. SMALPs preserve the native environment of MPs, facilitating their detailed analysis through a wide range of biophysical techniques. Despite their advantages, SMA-based technologies face challenges such as sensitivity to divalent cations and instability under low pH conditions. Ongoing research focuses on developing next-generation polymers with enhanced properties, utilizing controlled polymerization techniques to obtain narrow molecular weight distributions and chain-end functionality. This paper explores various SMA derivatives and alternative polymer systems like poly(diisobutylene--maleic acid) (DIBMA) and polymethacrylates, offering potential solutions to current limitations and expanding the toolkit for MP research and application.
