Carboxylated red fluorescent polystyrene microspheres provide optimized fluorescence intensity, superior surface reactivity, and enhanced biomolecule binding. Designed for biomedical imaging and diagnostic applications, they ensure effective signal detection, extended durability, and high adaptability.
Product Overview
Carboxylated red fluorescent polystyrene microspheres are synthesized by incorporating red fluorescent dye (with an excitation wavelength around 532 nm and an emission wavelength around 612 nm) and introducing carboxyl groups onto the surface. The fluorescent dye is effectively encapsulated within the microsphere, preventing fluorescence quenching and reducing the impact of environmental factors on fluorescence intensity. These microspheres exhibit uniform particle size distribution, making them ideal for various biomedical and scientific applications.
Key Features
- Monodispersity: The microspheres have a uniform particle size distribution, ensuring consistent and reproducible experimental results.
- Fluorescent Properties: The encapsulated high-fluorescent dye ensures stable fluorescence emission that is not affected by environmental changes, effectively preventing fluorescence quenching.
- Customizable Particle Size: The particle size can be adjusted according to the application requirements, allowing flexibility for different uses.
- Surface Functionalization: The surface of the microspheres can be functionalized with carboxyl, amino, and other functional groups to enable specific biochemical functionalities.
- High Stability: The microspheres demonstrate excellent chemical and physical stability, allowing them to perform consistently under various environmental conditions.
Applications
- Biomedical Research: Widely used in cell labeling, imaging, and drug delivery systems, with applications in cell biology, molecular biology, and biochemistry.
- High-Throughput Drug Screening: These microspheres serve as signal carriers, helping to screen large numbers of compounds and identify potential drug candidates.
- Medical Diagnostics: Suitable for immunoassays and diagnostic tests, with surface functional groups that do not interfere with the detection process.
- Tracer Studies: Fluorescent microspheres can act as tracers in studies of phagocytosis, pore size determination, and other biological processes, enabling real-time monitoring of cellular activities.
