在之前工作中，我们提出了一个能在不消耗信息或外部能量的情况下诱导持续定向输运的理论模型。然而，先前提出的实验验证方案在技术上具有挑战性，该模型尚未经过实验测试。在这项工作中，我们提出了一个大大简化的实验设计。通过表面修饰在金针尖端引入亲水性官能团，并将针压在两个液 - 气界面之一上，使压缩界面的离子浓度高于另一个界面，从而维持它们之间的浓度差。此设计将制造要求从纳米级降低到微米级，大幅降低了实验复杂性，并便于对所提出的机制进行实验检验。
英文摘要
In our previous work, we proposed a theoretical model capable of inducing sustained directed transport without consuming information or external energy. However, the experimental verification schemes proposed previously were technically challenging, and the model has therefore not yet been experimentally tested. In this work, we propose a greatly simplified experimental design. By introducing hydrophilic functional groups onto the tip of a gold needle through surface modification and pressing the needle against one of two liquid-vapor interfaces, the compressed interface is maintained at a higher ionic concentration than the other interface, thereby sustaining a concentration difference between them. This design reduces the fabrication requirement from the nanometer scale to the micrometer scale, substantially lowering experimental complexity and facilitating experimental examination of the proposed mechanism.
