🔬 Common Scientific Applications
🎯 pH sensing (ratiometric): Dual-wavelength intensity shifts enable quantitative pH mapping in solutions and model systems.
🔬 Fluorescence microscopy/imaging: Bright, water-soluble probe for pH visualization in in-vitro imaging workflows.
💧 Microfluidics & mixing studies: Tracer for flow, diffusion, and mixing with pH-dependent contrast in chips and channels.
🧪 Buffer/assay development: Monitor pH drift during enzyme/protein assays; verify buffer capacity and stability.
📏 Calibration standards: Prepare pH calibration curves for spectrofluorometers/plate readers (method validation & QC).
🧷 Materials & hydrogels: Embed to map local pH in polymers, membranes, and gel matrices during curing or transport tests.
🌿 Environmental testbeds: Indicator for water quality microcosms, soil eluates, and acid–base neutralization studies.
🔁 Transport/permeability assays: Track membrane permeability and compartmental pH changes in model vesicles and films.
Optical Properties
⚡ Excitation (λₑₓ): ~405 nm (blue light)
✳️ Emission (λₑₘ): ~512 nm (green fluorescence)
📈 Behavior: Fluorescence intensity varies systematically with pH, enabling ratiometric monitoring.
R&D use only. Spectral response depends on pH, ionic strength, and matrix; verify instrument filters and consult the SDS/CoA for your lot.
