Carboxylated green fluorescent polystyrene microspheres provide optimized fluorescence intensity, superior surface functionality, and enhanced biomolecule binding. Designed for biomedical imaging and diagnostic applications, they ensure precise signal detection, extended durability, and high adaptability.
Product Overview
Carboxylated green fluorescent polystyrene microspheres are synthesized by incorporating green fluorescent dye (with an excitation wavelength of 498–516 nm) and introducing carboxyl groups on the surface. The fluorescent dye is effectively encapsulated within the microsphere, preventing fluorescence quenching and minimizing the effects of environmental factors on fluorescence intensity. These microspheres exhibit uniform particle size distribution, making them ideal for a variety of biomedical and scientific applications.
Key Features
- Monodispersity: The microspheres have a narrow and uniform particle size distribution, ensuring consistent and reproducible results in experiments.
- Fluorescent Properties: The encapsulated fluorescent dye ensures stable fluorescence emission that is unaffected by environmental changes, effectively preventing fluorescence quenching.
- Customizable Particle Size: The microsphere size can be tailored to meet specific requirements based on the synthesis conditions, enabling versatility for different applications.
- Surface Functionalization: The surface of the microspheres can be functionalized with carboxyl, amino, and other functional groups, enabling specific biochemical interactions for targeted applications.
- High Stability: These microspheres exhibit excellent chemical and physical stability, making them suitable for use in various environmental conditions and ensuring long-lasting performance.
Applications
- Biomedical Research: Widely used for cell labeling, imaging, and as carriers for drug delivery systems, these microspheres are essential in cell biology, molecular biology, and biochemistry.
- High-Throughput Drug Screening: Serve as signal carriers to facilitate the screening of large numbers of compounds and identification of potential drug candidates.
- Medical Diagnostics: Used in immunoassays and diagnostic tests, the surface functional groups do not interfere with the detection process, ensuring accurate results.
- Tracer Studies: Act as tracers in studies of phagocytosis, pore size determination, and other biological processes, enabling real-time monitoring of cellular processes.
