At present, in the field of drug delivery, great consideration is given to colloidal systems and especially to polymeric nanoparticles and nanogels because of their characteristics, such as biocompatibility, biodegradability, water solubility, and ability of incorporation and preservation of drugs. The great benefit of these devices is the possibility to functionalize their surface through proper coating agents to improve their ability in targeted drug delivery and be able to treat specific tissues of human body. Obviously, many strategies are available, and the choice is strictly case-dependent. In this review, we illustrate the most important techniques of nanoparticles’ surface functionalization. Moreover, a detailed focus on the use of polymers, cell membranes, proteins, antibodies, and hybridized DNA structures as coating strategies is provided, together with a comparison of their characteristics, advantages, and disadvantages.
