An Experimental Comparison Between FTIR and Raman Microspectroscopy Applied to the Morphological Analysis of Microplastics in Drinking Water
AI summary Read the abstract
Researchers compared two advanced chemical identification techniques — FTIR and Raman microspectroscopy — for detecting microplastics in drinking water, helping establish which method is more reliable for routine water quality monitoring and public health protection.
Fourier-Transform InfraRed micro-spectroscopy (µFTIR) was applied to the microplastic (MP) analysis of drinking water samples taken from the inlet and outlet of a groundwater-fed waterworks located in Denmark. The outcome of the µFTIR analysis was then...

Raman Spectroscopy Based Approaches for Microplastics Investigations
AI summary Read the abstract
Researchers reviewed Raman spectroscopy-based approaches — including confocal Raman microscopy, surface-enhanced Raman scattering, and automated imaging — for identifying and characterizing microplastics in environmental samples, highlighting their superior chemical specificity compared to FTIR for sub-10-μm particles. Accurate chemical identification of microplastics at the nanoscale is foundational for both environmental monitoring and toxicological research, as particle composition (polymer type and additives) strongly influences biological harm.
Microplastics Characterization by Raman Microscopy
AI summary Read the abstract
Raman microscopy has emerged as a powerful tool for identifying and characterizing microplastics at small particle sizes that are difficult to analyze with other methods, enabling more accurate quantification in environmental samples. Improving characterization techniques is critical because smaller microplastic particles are more numerous and more likely to be ingested by a wider range of organisms, including humans.
Microplastics Characterization by Raman Microscopy
AI summary Read the abstract
Raman microscopy enables reliable identification and quantification of microplastics in environmental samples, with smaller particles posing greater ecological risk due to their higher numbers and broader species exposure. Standardizing this analytical technique is essential for producing comparable data across studies and informing effective pollution monitoring.
