Methyl-Modified Green Fluorescent Polystyrene Microspheres

Product Overview

Methyl-modified green fluorescent polystyrene microspheres are created by embedding green fluorescent dye (with fluorescence emission wavelengths between 498-516 nm) into polystyrene microspheres and modifying their surface with methyl groups. These microspheres offer uniform particle size distribution, ensuring consistent performance across various applications. The fluorescent dye is effectively encapsulated within the microspheres, preventing fluorescence quenching and reducing the impact of external environmental factors on fluorescence intensity.

Key Features

• Monodispersity: These microspheres exhibit a narrow particle size distribution, ensuring consistent and reproducible results in experiments.
• Fluorescence Characteristics: High fluorescence dye is embedded inside the microspheres, providing stable fluorescence emission that is unaffected by environmental changes.
• Customizable Particle Size: The size of the microspheres can be adjusted based on synthesis conditions, allowing for versatility in meeting different application requirements.
• Surface Functionalization: The microsphere surface can be chemically modified with functional groups like carboxyl, amino, and others, enabling specific biochemical functions.
• High Stability: The microspheres maintain both chemical and physical stability across a variety of experimental conditions, ensuring reliability in diverse environments.

Applications

• Biomedical Research: These microspheres are ideal for cell labeling, imaging, and as carriers in drug delivery systems. They are extensively used in cell biology, molecular biology, and biochemistry.
• High-Throughput Drug Screening: As signal carriers, they aid in quickly screening large numbers of compounds to identify potential drug candidates.
• Medical Diagnostics: Used in immunoassays and diagnostics, the functional groups on the microsphere surface remain stable and do not interfere with immunoanalysis results.
• Tracer Studies: Employed in phagocytosis studies and pore size measurement, these microspheres act as tracers to monitor cellular uptake processes.
