Self-assembled monolayers (SAMs) on glass were used as a platform to sequentially deposit fluorophores and small molecules for ion sensing. The preorganization provided by the surface avoids the need for complex receptor design, allowing for a combinatorial approach to sensing systems based on small molecules. The resulting libraries are easily measured and show varied responses to a series of both cations and anions. This technology is transferable from the macro- to the microscale both via microcontact printing (microCP), where the fluorophore is printed onto a glass surface, and via direct attachment of the fluorophore to microchannel walls. The ease of miniaturization of this technology may make the generation of a wide variety of simple yet efficient microarrays possible.
玻璃上的自组装单分子层(SAMs)被用作一个平台,用于依次沉积荧光团和小分子以进行离子传感。表面提供的预组织避免了复杂受体设计的需求,从而允许基于小分子的传感系统采用组合方法。由此产生的文库易于测量,并且对一系列阳离子和阴离子都表现出不同的响应。这项技术既可以通过微接触印刷(microCP)从宏观尺度转移到微观尺度,即将荧光团印刷到玻璃表面,也可以通过将荧光团直接附着到微通道壁上来实现。该技术易于小型化,这可能使生成各种各样简单而高效的微阵列成为可能。
