Raman Spectroscopy for Faster and Accurate Detection of Microplastics

What is it about?

Microplastic pollution is a growing concern because of its harmful effects on the environment and living organisms. To accurately assess the risks, scientists need reliable data on the amount, size, and composition of these tiny particles. Raman microscopy is a powerful tool for analyzing very small microplastics, but its use is limited by challenges like long testing times and interference from other materials. This review explores these challenges and presents practical solutions to improve the speed and accuracy of Raman microscopy. It also highlights advanced techniques that could allow for real-time detection and imaging of microplastics, helping researchers better understand and address this environmental issue.
