| Summary: | Cancer is among the most common causes of death in the world that affects a large number of people every year. Curcumin is one of the natural anticancer therapeutics with little or no negative effects. However, due to its hydrophobic nature, poor bioavailability, limited gastrointestinal uptake, and fast metabolism, its therapeutic applications are constrained. Therefore, the Bovine Serum Albumin-Coated Copper Sulfide anoparticles (CuS@BSA) for curcumin (CUR) drug delivery were synthesized and characterized, and then curcumin release from the nanosystem. Hemotoxicity, and cytotoxicity was investigated. This study involved the one-step synthesis of CuS@BSA nanoparticles first, followed by the addition of CUR. Then the synthesized nanoparticles were characterized employing Scanning Transient Electron Microscopy (STEM), Ultraviolet–visible spectroscopy (UV–vis) and Fourier-transform infrared spectroscopy (FT-IR) techniques. The Size and surface charge (zeta potential) of synthesized nanoparticles were determined by Dynamic Light Scattering (DLS) to be 120 nm and −13 eV, respectively. The results showed that the CUR loading was around 15% and also the release pattern of CUR was dependent on pH and increased in an acidic environment. The results of the hemolysis assay showed that the synthesized nanoparticles are not hemotoxic. The investigation of the cytotoxic effects of synthesized nanoparticles on cancer cells demonstrated that CuS@BSA nanoparticles did not exhibit any toxicity and therefore are an appropriate candidate for drug delivery.
