Finding dimensions

New analytical method makes nanoparticle research faster a nd more reliable

Nanoparticles are extremely small, yet within chemistry they are relatively large stru ctures. As a result, it is difficult to fully analyze them using exis ting techniques. Until now, researchers often had to perform multiple separate measurements to map various properties, such as size and co mposition. Verduin therefore developed a new 2D LC platform that brea ks through this limitation.

The method combines various analyti cal techniques and automates the process, allowing the size of nanopa rticles to be determined accurately while simultaneously opening the particles to analyze their contents. This allows both properties to b e directly correlated. Verduin successfully tested the approach on tw o key types of nanoparticles: polymers and lipids. In both cases, it proved possible to quickly and reliably measure both the structure an d the content. Measuring multiple properties simultaneously

The new method offers significant benefits for both science and society. Because multiple properties are measured simultaneously, analyses ar e faster, simpler, and less prone to errors. Moreover, less sample pr eparation is required, saving time and costs. This has direct applica tions in various sectors.

In medicine, for example, nanoparticl es play a key role in modern vaccines. With this method, it is possib le to verify in a single analysis whether the particles are the corre ct size and contain sufficient active substance, which accelerates qu ality control and production. In industry, too, for instance in coati ngs and other materials, better insight into nanoparticles leads to m ore efficient and safer products. Additionally, the technique can con tribute to environmental research, such as the detection and analysis of nanoplastics, a growing problem. By better understanding how nano particles are structured and function, researchers and companies can ultimately develop safer and more effective applications.

DESCRIPTION: Finding dimensions

New analytical method makes nanopa rticle research faster and more reliable

Chemist Joshka Verduin h as developed a new analytical method that allows both the size and co ntent of nanoparticles to be determined simultaneously. This innovati on can significantly improve research into and the use of nanoparticl es in areas such as medicine, coatings, and environmental studies.Nan oparticles are extremely small, yet within chemistry they are relativ ely large structures. As a result, it is difficult to fully analyze t hem using existing techniques.
