Aqueous suspensions of microspheres were infused around gels of varying composition. The solutes were excluded from zones on the order of 100 microm 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.
将微球水悬浮液注入不同成分的凝胶周围。溶质被排除在距离凝胶表面约100微米的区域之外。我们提供的证据表明，这一发现并非人为现象，并且溶质排斥力存在的距离远大于传统理论的预测。这些观察结果表明，溶质之间的相互作用范围可能出乎意料地长。
