NanoSight, manufacturers of unique nanoparticle characterization technology, is pleased to report that the School of Chemical Engineering at the University of Birmingham is using multiple NanoSight nanoparticle characterization systems to study viruses and catalyst nanoparticles. Working in the group of Professor Kevin Kendall, Marie-Curie Research Fellow, Dr Shangfeng Du, says "it's a very good tool for us to characterize the molecular adhesion and fracture, and interaction between particles in the research areas of catalysts and the biosciences."
DU博士的研究集中在燃料电池的催化剂纳米颗粒上。yabo214这项工作的一个重要重点是PT，Ni和基准金属的纳米颗粒催化剂的合成，尤其是在其结构中产生新的聚集度，以表征纳米颗粒以定义新的结构，组成，过程和过程。yabo214
对于催化剂表征，了解基于数字的粒径非常重要，因为它直接与催化性能联系在一起。通过了解悬浮液中颗粒的尺寸分布，可以获得有关分子粘附的信息，例如单线，双线，三重径yabo214和较大的聚集。这在理解分散体的处理方面非常有用。
Before finding out about NanoSight, the group mainly used electron microscopy (TEM and SEM) and dynamic light scattering (DLS) to measure particle size and aggregation. The main benefit of NanoSight's nanoparticle tracking analysis (NTA) is that it tracks particles individually making it possible to analyze small aggregations like doublets or triplets which were not seen by DLS. Moreover, it can be used to analyze the sample using a very low concentration which is very difficult by DLS or electron microscopy techniques.
The successes at Birmingham have led to Dr Du saying "I believe we'll get more achievements in this area." This work has already been expanded into the measurement of molecular interactions between nanoparticles and could have significant application use in a number of fields. One such area is on-line calibration of virus number concentrations which may be studied simultaneously with the interactions of viruses with polymer surfaces.
