New analytical method makes nanoparticle research faster and more reliable

Nanoparticles are extrem ely small, yet within chemistry they are relatively large structures. As a result, it is difficult to fully analyze them using existing te chniques. Until now, researchers often had to perform multiple separa te measurements to map various properties, such as size and compositi on. Verduin therefore developed a new 2D LC platform that breaks thro ugh this limitation.

The method combines various analytical tec hniques and automates the process, allowing the size of nanoparticles to be determined accurately while simultaneously opening the particl es to analyze their contents. This allows both properties to be direc tly correlated. Verduin successfully tested the approach on two key t ypes of nanoparticles: polymers and lipids. In both cases, it proved possible to quickly and reliably measure both the structure and the c ontent. Measuring multiple properties simultaneously

The new me thod offers significant benefits for both science and society. Becaus e multiple properties are measured simultaneously, analyses are faste r, simpler, and less prone to errors. Moreover, less sample preparati on is required, saving time and costs. This has direct applications i n various sectors.

In medicine, for example, nanoparticles play a key role in modern vaccines. With this method, it is possible to v erify in a single analysis whether the particles are the correct size and contain sufficient active substance, which accelerates quality c ontrol and production. In industry, too, for instance in coatings and other materials, better insight into nanoparticles leads to more eff icient and safer products. Additionally, the technique can contribute to environmental research, such as the detection and analysis of nan oplastics, a growing problem. By better understanding how nanoparticl es are structured and function, researchers and companies can ultimat ely develop safer and more effective applications.

DESCRIPTION:

New analytical method makes nanoparticle research fas ter and more reliable

Chemist Joshka Verduin has developed a new analytical method that allows both the size and content of nanoparti cles to be determined simultaneously. This innovation can significant ly improve research into and the use of nanoparticles in areas such a s medicine, coatings, and environmental studies. Nanoparticles are ex tremely small, yet within chemistry they are relatively large structu res. As a result, it is difficult to fully analyze them using existin g techniques. Until now, researchers often had to perform multiple se parate measurements to map various properties, such as size and compo sition. Verduin therefore developed a new 2D LC platform that breaks through this limitation. The method combines various analytical techn iques and automates the process, allowing the size of nanoparticles t o be determined accurately while simultaneously opening the particles to analyze their contents. This allows both properties to be directl y correlated. Verduin successfully tested the approach on two key typ es of nanoparticles: polymers and lipids. In both cases, it proved po ssible to quickly and reliably measure both the structure and the con tent. Measuring multiple properties simultaneously The new method off ers significant benefits for both science and society. Because multip le properties are measured simultaneously, analyses are faster, simpl er, and less prone to errors. Moreover, less sample preparation is re quired, saving time and costs. This has direct applications in variou s sectors. In medicine, for example, nanoparticles play a key role in modern vaccines. With this method, it is possible to verify in a sin gle analysis whether the particles are the correct size and contain s ufficient active substance, which accelerates quality control and pro duction. In industry, too, for instance in coatings and other materia ls, better insight into nanoparticles leads to more efficient and saf er products. Additionally, the technique can contribute to environmen tal research, such as the detection and analysis of nanoplastics, a g rowing problem. By better understanding how nanoparticles are structu red and function, researchers and companies can ultimately develop sa fer and more effective applications.
