Abstract:  

In this work, the preparation of novel calcium citrate (CaCit) nanoparticles (NPs) has been disclosed and the use of these NPs as “Trojan” carriers has been demonstrated. The concentration ratio between calcium ions and citrate ions was optimized, yielding spherical NPs with size in the range of 100–200 nm. Additionally, a fluorescent dye, fluorescein isothiocyanate (FITC), was successfully encapsulated by the coprecipitation method. The products were characterized by thermogravimetric analysis and scanning electron microscopy. The cellular uptake was investigated by incubating the synthesized fluorescent-tagged NPs with human keratinocytes using a confocal microscope. The accumulation of the FITC in the cells suggested that the CaCit NPs can potentially be used as novel drug carriers.
