Fluorescent Particles, Nile Red, 1%w/v, 0.7-0.9µm, 2mL

Our Fluorescent Particles, Nile Red, 1% w/v, 0.7–0.9 µm – 2 mL are high-quality, monodisperse fluorescent polystyrene microspheres designed for microscopy, particle tracking, and flow-based assays. Each particle is internally labeled with Nile Red, a bright, photostable fluorophore with excitation/emission ~535/575 nm, producing strong red–orange fluorescence compatible with standard fluorescence filter sets.

The 0.7–0.9 µm particle size makes these beads ideal for nanoparticle tracking, flow studies, and environmental microplastic detection. The 1% w/v aqueous suspension ensures optimal particle concentration for direct use in imaging or calibration experiments.
