    Cobalt-60 gamma irradiation effectively synthesizes hydrophilic functional microspheres from 2-hydroxyethyl methacrylate. These microspheres, useful for cell labeling, demonstrate controlled particle size via monomer concentration and stabilization techniques.

    Area of Science:

    • Polymer Chemistry
    • Materials Science
    • Biotechnology

    Background:

    • Hydrophilic functional microspheres are valuable in biomedical applications.
    • Controlling microsphere size and distribution is crucial for their efficacy.
    • Gamma irradiation offers a versatile method for polymer synthesis.

    Purpose of the Study:

    • To investigate the synthesis of hydrophilic functional microspheres using Cobalt-60 gamma irradiation.
    • To explore the influence of various factors on microsphere characteristics.
    • To evaluate the utility of these microspheres in biological labeling.

    Main Methods:

    • Synthesis of 2-hydroxyethyl methacrylate microspheres via Co gamma irradiation.
    • Investigation of monomer concentration, steric stabilization, and electrostatic interactions.
