Product Name

Name：Carboxyl modified red fluorescent polystyrene microspheres

^{Product Overview}

Carboxyl modified red fluorescent polystyrene microspheres are prepared by adding a red fluorescent dye that excites around 532 and emits around 612 during the preparation of polystyrene microspheres, and then modifying them with carboxyl groups. Customizable size range of 20nm-5 μ m. These microspheres have a uniform particle size distribution, which enables them to exhibit consistent performance in various applications. Fluorescent dyes are embedded inside the microspheres, effectively preventing fluorescence quenching and reducing the influence of environmental factors on fluorescence intensity.

^{Product Features}

Monodispersibility: The uniform particle size distribution of microspheres helps ensure consistency and reproducibility of experimental results.

Fluorescence characteristics: Contains highly fluorescent dyes that are embedded inside the microspheres, effectively preventing fluorescence quenching.

Adjustable particle size: By controlling the synthesis conditions, microspheres with different particle sizes can be prepared to meet different application requirements.

Surface functionalization: The surface of microspheres can be chemically modified by introducing specific functional groups, such as carboxyl and amino groups, to achieve specific biochemical functions.

High stability: Microspheres have good chemical and physical stability and are suitable for use in various environments.

Optical performance: The fluorescence emission of fluorescent microspheres is stable and not affected by changes in external environmental media.

Application Fields

Biomedical research: Fluorescent polystyrene microspheres can be used for cell labeling, imaging, and as carriers for drug delivery systems in fields such as cell biology, molecular biology, and biochemistry.

Standard measurement: As an instrument calibration particle, used to calibrate analytical instruments and ensure measurement accuracy.

High throughput drug screening: As a signal carrier, it helps to quickly screen a large number of compounds and search for potential drug candidates.

Medical diagnosis: In areas such as immune analysis and detection, the surface of microspheres retains their original functional groups, which will not affect immune analysis and detection.

Tracer research: In fields such as phagocytosis research and pore size determination, fluorescent microspheres can be used as tracers to monitor cellular endocytosis processes.
