In this paper, the principles of the action of the selective (NaIO4 and 2,2,6,6-tetramethylpiperidine-1-oxyl-TEMPO radical) and non-selective (H2O2 and KMnO4) oxidation agents on cellulose are presented. Their importances in modifying the existing properties or giving new properties to cellulosic materials, as well as examples of their applications are also given. The oxidation product - oxicellulose, presents the base for obtaining a wide range of materials for special applications. Particularly, the influence of TEMPO-mediated oxidation on natural and man-made cellulosic fibers is presented, with a detailed overview on the type and quantity of introduced functional groups, changes in structure, sorption and mechanical properties. Also, we described the use of TEMPO-mediated oxidation for the production of cellulosic nano-materials in the form of dispersions, particles and films, as well as the potential application of these nano-structural materials.
