The formation of self assembled nano-structures from the biopolymer laminarin dried onto mica is reported. The observed structures are composed of stacked terraced layers decreasing in size away from the mica surface. The layers display a high degree of dimensional regularity as observed using atomic force microscope imaging (AFM). The width of the layers is linearly dependent upon the number of layers in the structure and decreases with layer number away from the mica substrate. The thickness of the layers is uniform throughout the structure. A pore is contained in the central region of each structure with more than one layer. We postulate that these structures have potential use as templates in microelectronic devices and sensors where the central pore has the potential to immobilise functional materials.
报道了从干燥在云母上的生物聚合物海带多糖形成自组装纳米结构的过程。观察到的结构由堆叠的梯田状层组成，这些层的尺寸远离云母表面逐渐减小。使用原子力显微镜成像（AFM）观察到，这些层表现出高度的尺寸规则性。层的宽度与结构中的层数呈线性相关，并随着远离云母基底的层数增加而减小。层的厚度在整个结构中是均匀的。每个具有多层的结构的中心区域都包含一个孔。我们推测这些结构在微电子器件和传感器中具有作为模板的潜在用途，其中中心孔有可能固定功能材料。
