Preparation and Characterization of Chitosan and Inclusive Compound-Layered Gold Nanocarrier to Improve the Antiproliferation Effect of Tamoxifen Citrate in Colorectal Adenocarcinoma (Caco-2) and Breast Cancer (MCF-7) Cells

Abstract

Objectives: Cancer diseases have been linked to a huge number of causes that led to deaths in this century along with cardiovascular and lung diseases. Most death-leading types of cancer are colon, lung, breast, and prostate cancers. Due to the remarkable properties of gold (Au) nanocarrier, they are used to deliver and improve tamoxifen (Tam) citrate activity in Caco-2 and MCF-7 cells. Materials and Methods: In this study, preparation of Au nanoparticles (NPs), zeta-potential and size, high resolution transient electron microscopy (HRTEM), high-performance liquid chromatography, ultraviolet-visible spectra, fluorescence microscopy, fourier infrared spectroscopy, and real-time cellular analysis xCELLigence technology were investigated. Results: value <0.00001). Conclusion: -CD-HA-Chi-Au nanocomposite is a potential nanocarrier for delivering the drug to Caco-2 and MCF-7 cancer cells, since it has improved Tam citrate activity on colorectal cancer cells. After all, the developed formula showed more effect on Caco-2 than MCF-7. The prepared nanocomposite could be used to improve the cancer therapy in clinical trials.
