通过真正的纳米级控制引导生物分子在表面上自组装的能力是创建功能性基材的关键。在此,我们报告了通过纳米图案表面上的选择性自组装和最小化非特异性吸附来制造纳米级生物分子阵列。我们证明所开发的平台可以在单分子水平上同时筛选特定的蛋白质/DNA 结合事件。这里提出的策略具有普遍适用性,并且能够以单分子分辨率实时高通量监测生物活性。
The ability to direct the self-assembly of biomolecules on surfaces with true nanoscale control is key for the creation of functional substrates. Herein we report on the fabrication of nanoscale biomolecular arrays, via selective self-assembly on nanopatterned surfaces and minimized non-specific adsorption. We demonstrate that the platform developed allows for the simultaneous screening of specific protein/DNA binding events at the single-molecule level. The strategy here presented is generally applicable, and enables high throughput monitoring of biological activity in real-time and with single-molecule resolution.
