Micelle-forming polymers such as poloxamer 407 (P407) are promising drug nanocarriers, yet their sol–gel transition under physiological conditions remains poorly understood. In a recent study, researchers from Japan experimentally analyzed how P407 micelles interact in saline environments mimicking bodily fluids. Using advanced X-ray and light scattering techniques, they shed light on key inter-micellar interactions and structures that influence gelling behavior, providing crucial insights for future drug nanocarrier design.

Poloxamer 407 self-assembles into micelles in solution and turns into a gel at around body temperature. This study revealed important differences in how these micelles interact and organize into gels depending on the salts and ions present in the solution, which could ultimately affect key properties for drug nanocarrier technologies like the drug release rate.
