ClearAnalyzing microplastics with Nile Red: Emerging trends, challenges, and prospects
This review evaluates the Nile Red staining technique as an analytical method for identifying and quantifying microplastics in environmental samples. The study concludes that while Nile Red has emerged as a viable low-cost alternative to visual identification for microplastics research, not everything that fluoresces is plastic, so additional spectroscopic analysis is needed to validate results.
