Abstract
This disclosure relates to polyethylene glycol (PEG)-functionalized nanoparticles comprising a functional agent, and preparation methods, properties and applications thereof. The nanoparticle represented by PEG-L-G/P, comprising a type of hydrophilic PEG, a hydrophobic functional agent G, which are covalently linked by L: a linker or a chemical bond, and a type of hydrophobic polymer P. The G and P form the hydrophobic core, while the PEG constitutes the hydrophilic outer layer of the nanoparticle in an aqueous medium. The functional agent comprises one or more functional compounds including a therapeutic drug, an imaging diagnostic agent, a photoelectric responsive diagnostic agent, an immune-stimulating agent, or a combination thereof. The nanoparticles comprising such functional agent can offer various applications in multiple biomedical fields.
