通过在空气-水界面形成未改性金属氧化物纳米颗粒的Langmuir膜改变薄膜物理性质的方法

报告内容简介：金属氧化物纳米颗粒(NPs)薄膜因其可能具备的光学和电学特性，在纳米技术领域如半导体和太阳能电池中被广泛应用。通过在空气-水界面形成纳米颗粒的Langmuir薄膜，然后将这些薄膜沉积或烧结到衬底上，可以制备出具有可控堆积密度的纳米颗粒薄膜。然而，金属氧化物纳米颗粒 (如SiO2或TiO2)的Langmuir膜不能在空气-水界面形成，因为它们的高亲水性使其在空气-水界面上不稳定。克服这一问题的常用方法是使用表面活性剂或聚合物对纳米颗粒进行疏水改性。 在本次讲座中，我们将讨论另外一种使未改性金属氧化物纳米颗粒在空气-水界面稳定的替代方法，该方法涉及向水相中添加无机盐。我们还将探讨如何通过在空气-水界面混合不同尺寸和类型的纳米颗粒来改变转移薄膜的物理性质如粗糙度和表面电荷等。 报告人简介：Cathy McNamee教授,日本信州大学

什么是Langmuir膜

Langmuir膜是漂浮在液-气界面或者液-液界面上的原子、分子甚至纳米颗粒构成的不溶性单层。液体表面不溶性分子的自组装力可以促使单层薄膜的形成。 许多材料都可以形成Langmuir膜 当分子具有疏水和亲水基团时，它们可以在整个薄膜上以可预测的方式在水面上定向排列，从而为进一步控制沉积分子膜的结构提供了惊人的可能性。 分子材料的混合物可以结合在一个单层中创建出全新的特性。这些性质可以通过控制分子堆积密度来调节，从而控制相邻分子相互作用的程度。 许多分子材料非常适合在气-液界面处形成不溶层。 这些物质包括脂质、纳米颗粒、聚合物、蛋白质和许多其他生物分子。 现代化学工程使合成几乎所有类型的具有疏水基团的功能分子成为可能，这些疏水基团使它们不溶于水从而适合于形成单分子层。 最近的研究表明，碳纳米管、纳米线或石墨烯等新型化合物都可以形成Langmuir膜&#823&#823

阿尔茨海默症（AD）是现阶段全球最普遍的神经退行性疾病。它影响了至少10%的65岁以上中老年人。尽管疾病严重，由于神经心理学测试和神经成像的准确性低及成本过高，AD的早期诊断仍然具有非常大的挑战性。 在这篇文章中，作者使用Langmuir-Blodgett膜分析仪成功制备出密集排列的碳纳米管（CNT）。而相对于传统商业化的ELISA方法检测，LB自组装CNT阵列方法可以将检测灵敏度提升10-1000倍。这项工作证明了基于LB方法的碳纳米管阵列生物传感器可用于早期AD诊断。

如何沉积氧化石墨烯薄膜?

氧化石墨烯(GO)是石墨烯的氧化形态。它是一种由石墨氧化形成的单原子层材料，价廉、易得。氧化石墨烯薄膜在许多领域中都有应用，如光电子学和生物传感器。由于氧基团的存在，氧化石墨烯是亲水性的，因此可以分散到水中。分散性使氧化石墨烯的溶液沉积成为可能。 溶液法制备氧化石墨烯薄膜 氧化石墨烯最大的优点之一是它在水和其他有机溶剂中的优良分散性。这使得使用溶液法沉积石墨烯成为可能。这种方法通常比气相沉积更省时，花费更低的设备成本。氧化石墨烯的许多应用里都要求在大面积基材上沉积形貌清晰、连续的单层薄膜。而单层的氧化石墨烯的形貌很难用最典型的、基于溶液的沉积方法控制，如旋涂或滴铸。简而言之，Langmuir-Blodgett方法（简称LB）已被成功地用于沉积界面清晰的纳米颗粒薄膜，而且该方法还可以更好地控制氧化石墨烯的单层膜沉积。 想了解更多关于Langmuir-Blodgett方法和布鲁斯特角显微镜的信息，请下载附件点击链接观看网络研讨会《如何用LB法沉积氧化石墨烯薄膜？》。

如何制备出更好的纳米颗粒薄膜传感器？

传感器是能够检测环境变化，将该变化转换为信号并将其发送以供人或仪器读取的装置。 传感器种类很多，有非常简单的温度传感器也有复杂的电化学传感器。与传统的传感器相比，基于纳米颗粒薄膜的传感器具有多种优势，例如：更好的灵敏度和选择性，特别是在电化学传感方面。纳米颗粒传感层的制备是最主要的挑战。我们常用的两种主要方法是层层自组装（LbL）和Langmuir-Blodgett（LB）法。 纳米颗粒薄膜作为传感元件 使用纳米颗粒（NP）作为传感元件的主要优点之一是纳米颗粒的尺寸和表面特性可以通过制备过程进行调节。通过微调纳米颗粒的性质，可以实现高选择性和高灵敏度。纳米颗粒可提供更大的有效传感器表面积，这也可以进一步提高灵敏度。 表界面上纳米颗粒的大小和分布影响着电化学传感器的性能。由于能形成具有确定结构的沉积，预合成和功能化的胶体纳米颗粒最常用于传感器应用。 层层自组装 层层自组装是一种将不同的材料层依次沉积在固体基体上的技术，最简单的方法是通过浸渍涂层。 我们取一个初始带正电荷的基板。首先，将基板浸入含负电荷物质的溶液中，通过静电相互作用将负电荷物质吸附在基板表面。这会产生一个带负电荷的表面。然后将基板浸入漂洗溶液中，去除松散的物质，以防止下一种溶液受到污染。然后将基板浸入含有正电荷的溶液中，以产生带正电荷的表面。接下来是另一轮的冲洗步骤。此过程可以根据需要重复多次，以构建所需的多层结构。 Langmuir-Blodgett方法 使用LB方法时，沉积从Langmuir单层的形成开始。 Langmuir单层是通过将待沉积物铺展到在浅槽中的空气-水界面上而形成的。 LB槽设备包含可以精确受控移动的滑障，以减小界面的表面积，从而使待沉积物更紧密地结合在一起。当达到所需的堆积密度时，可以通过从空气-水界面提拉基板完成样品沉积。 通过重复该过程也可以实现多层结构的沉积。 层层自组装（LbL）和LB方法的比较 这两种技术的主要区别在于沉积发生的界面。更多详情，请联系百欧林。

混合磷脂单分子层和双分子层的纳米尺度表面性质

Mixed distearoylphosphatidylethanolamine (DSPE) and dioleoylphosphatidylethanolamine (DOPE) monolayers and bilayers have been deposited on mica using the Langmuir-Blodgett (LB) technique, as amodel systemfor biomembranes. Investigation with atomic forcemicroscopy revealed phase-separation for both monolayers in air and bilayers in water in the form of microscopic DSPE domains embedded in a DOPE matrix. For the monolayers in air, the step height measured between the higher DSPE phase and the lowerDOPE phasewas larger than expected fromthemolecular lengths, and a significant contrast in adhesion and frictionwas observed despite identical lipid end groups. This unexpected behavior resulted primarily froma difference in the filmmechanical properties, theDOPEphase being inelastically deformed by the probe. For the bilayers in water, similar trends were found in terms of height, adhesion, and friction, but an additional short-range repulsive hydration/steric force over the DSPE phase contributed to the observed differences.
