The conjugation of gold nanoparticles (AuNPs) with biomolecules could create many outstanding biofunctions for the surface-functionalized nanoparticles and extend their biomedical applications. In this review, we summarize the recent advances in the surface bioengineering of AuNPs with biomolecules, such as DNA, proteins, peptides, and biopolymers, in which the details on the structure, functions, and properties of surface- bioengineered AuNPs are discussed. In addition, the surface-biofunctionalization of AuNPs for biomedical applications like biosensing, bioimaging, drug delivery, and tissue engineering are introduced. It is expected that this work will be very helpful for readers to understand the surface functionalization and engineering techniques for various metallic nanoparticles and design novel biomaterials for biomedical applications.

Prostate and breast cancer are the current leading causes of new cancer cases in males and females, respectively. Phosphatidylserine (PS) is an essential lipid that mediates macrophage efferocytosis and is dysregulated in tumors. Therefore, developing therapies that selectively restore PS may be a potential therapeutic approach for carcinogenesis. Among the nanomedicine strategies for delivering PS, biocompatible gold nanoparticles (AuNPs) have an extensive track record in biomedical applications. In this study, we synthesized biomimetic phosphatidylserine-caped gold nanoparticles (PS-AuNPs) and tested their anticancer potential in breast and prostate cancer cells in vitro. We found that both cell lines exhibited changes in cell morphology indicative of apoptosis. After evaluating for histone-associated DNA fragments, a hallmark of apoptosis, we found significant increases in DNA fragmentation upon PS-AuNP treatment compared to the control treatment. These findings demonstrate the use of phosphatidylserine coupled with gold nanoparticles as a potential treatment for prostate and breast cancer. To the best of our knowledge, this is the first time that a phosphatidylserine-capped AuNP has been examined for its therapeutic potential in cancer therapy.
