Data Sheet 2_Systematic optimization of Nile Red staining parameters for the reliable detection of microplastics ≤ 2 µm.pdf is a 112.7 KB PDF document authored by Uroosa and last updated on 2026-04-23. It describes an optimized filtration and Nile Red staining protocol for detecting microplastics smaller than 5 µm, with a focus on particles ≤ 2 µm. The protocol is designed as a cost-effective alternative to techniques like FTIR and Raman spectroscopy for labs with lower resources.
A PDF document presents a systematically optimized filtration and Nile Red staining protocol for detecting microplastics smaller than 5 µm, with emphasis on particles ≤ 2 µm. The study, authored by Uroosa and last updated in April 2026, demonstrates the protocol's effectiveness on polystyrene and polyethylene particles while confirming dye specificity against inorganic controls. This cost-effective method is designed for labs with lower resources and for initial screening of natural samples.
