Carbon-based materials are from principles compatible with living organisms. Newly invented nanodiamond-based materials are characterized by their resistance to radiation and have good biological tolerance for a number of systemic tissues. Most recently it has been found that nanodiamond particles have antioxidant, antiinflammatory, antiallergic, antibacterial, and antitumor properties. There are a number of research communications indicating that detonation nanodiamond particles are fairly reactive and that their surface can be effectively modified by chemical, mechanical, and plasma-chemical methods. Plasma-chemical modification of detonation nanodiamond particles gives the possibility to control the surface of nanodiamond particles in biological tests. Such nanoparticles, obtained by the detonation method, reveal the biological activity that is strongly depending on surface functionalization. The antioxidant and antibacterial properties of detonation nanodiamond particles can be used as an active packaging technology in the cosmetic and food industries. Newly invented food packaging layers containing nanodiamonds may exhibit improved durability, flexibility, as well as temperature and humidity resistance. Moreover, incorporation of functionalized nanodiamonds to the polymer matrix of food packaging layers may significantly change the oxygen-barrier and antimicrobial properties of new packaging materials. This chapter summarizes the recent advances on research and applications of diamonds and nanodiamonds particles in the food industry, medicine, and cosmetology. Moreover, potential toxicological risk of nanodiamonds modified food packaging layers is highlighted and discussed.
