表面活性剂分子通常形成具有大纵横比的胶束，“蠕虫状”胶束，导致基于其缠结的网络结构。通过使用光镊，我们可以检测蠕虫状胶束溶液粘弹性的不均匀性，当测量时间尺度短于弛豫时间（胶束缠结发生溶解的时间）时，可以观察到这种不均匀性。
Surfactant molecules often form micelles with a large aspect ratio, “worm-like” micelles, leading to network structures based on their entanglements. By using optical tweezers, we could detect a heterogeneity in the viscoelastic properties of the worm-like micelle solution, which is observed when the measurement timescale is shorter than the relaxation time − the time at which dissolution of the micelle entanglements occurs.
