Abstract

It has long been known that inorganic nanoparticles (NPs) can interact with biological macromolecules and show a wider range of biomedical characteristics, including antibacterial, anticancer and antioxidant effects, which cannot be mimicked by their bulky counterparts. It is of great importance in their biomedical applications to study DNA damage in bacterial and cancer cells to develop biocompatible therapeutic nano-platforms derived from inorganic NPs. Therefore, to determine how DNA interacts with inorganic NPs serving as therapeutic agents, thermodynamic and structural studies are essential for an understanding of those mechanisms, thereby allowing for their modulation and manipulation of nano-bio interface. In this paper, we aimed to overview the biophysical techniques typically employ to study DNA–NP interactions as well as the mechanistic aspects of the interaction between different inorganic NPs and calf thymus DNA (CT-DNA), a well-known laboratory model, followed by a survey of different parameters affecting the interaction of NPs and DNA. The molecular interactions between inorganic NPs and DNA were then discussed in relation to their anticancer and antibacterial properties. As a final point, we discussed challenges and future perspectives to put forward the possible applications of the field. In conclusion, the interaction between NPs and DNA needs to be studied more deeply in order to develop potential NP-based anticancer and antibacterial platforms for future clinical applications.
