硅纳米线场效应晶体管的超分子界面已经开发,目的是创造再生电子生物传感器。该方法的关键是用β-环糊精(β-CD)官能化的Si-NW,受体部分可以用正交超分子连接体连接到所述Si-NW。在这里,我们展示了使用已知的最强的生物分子系统,链霉亲和素(SAV)-生物素的完全回收。结合的SAv和接头可以通过与浓缩的β-CD竞争性解吸而从表面选择性地去除,从而再生传感器以供重复使用。β-CD的另一个优点是立体选择性传感器的可能性,我们在这里证明了定量手性靶标的对映体组成的能力。
A supramolecular interface for Si nanowire FETs has been developed with the aim of creating regenerative electronic biosensors. The key to the approach are Si-NWs functionalized with β-Cyclodextrin (β-CD), to which receptor moieties can be attached with an orthogonal supramolecular linker. Here we demonstrate full recycling using the strongest biomolecular system known, streptavidin (SAv)-biotin. The bound SAv and the linkers can be selectively removed from the surface through competitive desorption with concentrated β-CD, regenerating the sensor for repeated use. An added advantage of β-CD is the possibility of stereoselective sensors, and we demonstrate here the ability to quantify the enantiomeric composition of chiral targets.
