In this paper, we present a new methodology for creating 3D ordered porous nanocomposites based on anodic aluminum oxide template with polyaniline (PANI) and silver NPs. The approach includes in situ synthesis of polyaniline on templates of anodic aluminum oxide nanomembranes and laser-induced deposition (LID) of Ag NPs directly on the pore walls. The proposed method allows for the formation of structures with a high aspect ratio of the pores, topological ordering and uniformity of properties throughout the sample, and a high specific surface area. For the developed structures, we demonstrated their effectiveness as non-enzymatic electrochemical sensors on glucose in a concentration range crucial for medical applications. The obtained systems possess high potential for miniaturization and were applied to glucose detection in real objects-laboratory rat blood plasma.
在本文中,我们提出了一种基于阳极氧化铝模板与聚苯胺(PANI)和银纳米颗粒创建三维有序多孔纳米复合材料的新方法。该方法包括在阳极氧化铝纳米膜模板上原位合成聚苯胺以及直接在孔壁上激光诱导沉积银纳米颗粒。所提出的方法能够形成具有高孔隙率纵横比、拓扑有序性以及整个样品性能均匀性和高比表面积的结构。对于所开发的结构,我们证明了它们作为非酶电化学传感器在医学应用关键浓度范围内检测葡萄糖的有效性。所获得的系统具有高度的小型化潜力,并应用于实际物体——实验大鼠血浆中的葡萄糖检测。
