Description
SPIO@SiO2-PEGs (PEG = polyethylene glycol) are SPIOs functionalised with a synthetic polymer (ethylene glycol). These are encapsulated in a thin layer of silica. They are water-soluble and often find applications in the biomedical sector and cosmetics.
SPIO@SiO2-PEGs increase the ability of nanoparticles to evade macrophages and improve their stability at physiological pH.
