在不同组成的凝胶周围注入微球的水悬浮液。溶质被排除在距离凝胶表面100 μ m左右的区域。我们提出的证据表明，这一发现不是人为的，而且溶质排斥力存在的距离远远大于传统理论预测的距离。这些观察结果表明，溶质之间的相互作用可能出乎意料地长。
Aqueous suspensions of microspheres were infused around gels of varying composition. The solutes were excluded from zones on the order of 100 mum from the gel surface. We present evidence that this finding is not an artifact, and that solute-repulsion forces exist at distances far greater than conventional theory predicts. The observations imply that solutes may interact over an unexpectedly long range.
