Nanoplastic and Optical-DOSY
We often talk about the "Plastic Age," but we are rapidly entering the "Nanoplastic Frontier." While microplastics have been the focus of research for years, nanoplastics—particles smaller than 1 micrometer—represent a unique scientific challenge.
Standard characterization techniques often fail at the nanoscale, especially when dealing with polydisperse samples (mixtures of different sizes). At InspectT, we are developing two cutting-edge techniques that might redefine what is possible.
Raman-DOSY and IR-DOSY: Solving the Polydispersity Puzzle
Nanoplastics in real-world environments are rarely uniform: They are a chaotic mix of various polymers and sizes. As shown in this article, Raman-DOSY (Diffusion Ordered Spectroscopy) and IR-DOSY (Infrared Diffusion Ordered SpectroscopY) can help for their analysis by providing:
Simultaneous Analysis: It combines Raman and IR chemical "fingerprinting" with DOSY’s ability to separate components based on their diffusion (size).
Accuracy: It provides a clear map of which polymer is which size, even in a "polydisperse" sample.
