纳米等离子体传感（NPS）

Insplorion—XNanoII 样本

纳米等离子体传感（NPS 局域表面等离子体（LSP）是金属纳米粒子中自由电子连贯的、集体的空间振荡，可以通过近可见光的电磁场来激发。当白光穿过等离子体的传感器时，由于光被粒子吸收和散射，导致消光光谱上出现消光峰，即共振峰。 共振峰的位置由纳米粒子的尺寸、形状和材料决定，更重要的是，它也取决于邻近纳米粒子的介质的折射率。因此，通过监控共振峰的变化，就可以检测和监控界面处发生的变化过程对传感器表面纳米粒子的介电环境产生的影响。

Application Note # 15 在金表面的偶氮苯功能化自组装单层膜的光开关

Insplorion's Nanoplasmonic Sensing (NPS) technology enables measurements of the photoisomerization kinetics of self-assembled monolayers of azobenzene-containing thiols in real time. In this application note it is shown how quantitative data on the photoinduced trans?cis and cis?trans isomerization processes in inert gas atmosphere was obtained as a function of irradiation intensity.

Application Note # 14 软物质吸附2：可控的膜结构

The different available surface coatings on Insplorion’s sensors enable control over the material composition of the surface. In this application example lipid membrane platforms (vesicles and bilayers) are assembled on Insplorion sensors with different surface chemistries (bare gold disks on glass and TiO2 and SiO2 coatings, respectively). Due to the extreme surface sensitivity of Insplorion's Nanoplasmonic Sensing (NPS) technique information is obtained not only on the lipid adsorption but also on the membrane architecture and subsequent membrane-peptide interactions.

Application Note # 13 软物质吸附1：脂囊泡的附着和变形动力学

The extreme surface sensitivity of Insplorion's Nanoplasmonic Sensing (NPS) technique makes it especially suited to study surface adsorption phenomena on the nanoscale. In this application example it is shown how NPS can be employed in a quantitative study of the kinetics of lipid vesicle adsorption. NPS provides information on both the attachment and deformation of adsorbed vesicles.

Insplorion's Localized Surface Plasmon Resonance (LSPR) technology enables in situ, real-time kinetics measurements of small molecule percolation and adsorption into thick mesoporous structures by probing the hidden internal interface. Both kinetic and quantitative (i.e. diffusion coefficient and surface coverage) information can be derived.

Application Note # 07 纳米粒子的烧结

Catalyst sintering is a major cause of catalyst deactivation, which yearly causes billions of dollars of extra cost associated with catalyst regeneration and renewal. In order to develop more sintering-resistant catalysts, a detailed under?standing of the sintering kinetics and mechanisms is required. It is therefore of great importance to investigate sin?tering in situ, in real time and under realistic catalyst operation conditions (i.e. at high temperatures and pres?sures in reactive gas atmospheres). Today there is a lack of available techniques that allow such studies. Using Pt/SiO2 as model catalyst, this Application Note illustrates that Indi?rect Nanoplasmonic Sensing (INPS) has the potential to fill this gap and provide novel real time data at low cost and with high throughput.

Application Note # 06 氧化钡的氮氧化合物存储动力学

NOx storage/release catalysts, in which NOx is temporarily accumulated in the catalyst before being reduced to N2, play a key role in automotive emission cleaning. They rely on an active material, for example barium oxide (BaO), which upon NOx storage is converted to Ba(NO3)2 or related compounds. Pt (and in practice usu?ally also Rh) is needed for the reduc?tion step and also for oxidation of NO (when present) to NO2 during the storage phase.

Application Note # 04 催化反应的光学纳米量热法

Introduction Dissipated heat from an exothermic catalytic reaction is a critical parameter for phenomena like catalytic ignition and light-off in catalytic converters for e.g. car emission cleaning. This application note illustrates the possibility to use the Insplorion’s Indirect Nanoplasmonic Sensing (INPS) platform to measure nanoscale local temperature changes and to exploit this for a novel optical nanocalorimetry of reactions on supported nanoparticle catalysts under realistic temperature and pressure conditions.
