The goal of this chapter is to review the most recent trends to produce cellulose nanoparticles and nanocomposites with biomedical applications. These particles could be named as bacterial cellulose, cellulose nanofibers, and cellulose nanocrystals. The production of these nanoparticles with diameters below 100 nm is challenging because of the strong agglomeration tendency which occur upon drying aqueous cellulose suspensions or during the compounding process with hydrophobic polymers. Typically, the physical and mechanical properties of these nanoparticles depend on the source of cellulose and the extraction process employed. Cellulose nanoparticles are obtained by mechanical, chemical, or enzymatic process treatments to open the structure of the cellulose source and facilitate accessibility to its microstructure. Usually, a combination of these processes makes the extraction more efficient.

In the present work was carried out the surface modification of microfibril and cellulose whiskers. Two different techniques were tested, one of them was the liquid phase modification and the other one, gas phase modification. Five reactants were tested, palmitoyl chloride, acetyl chloride, sebacoyl chloride and two anhydrides allow to functionalize the surface of the cellulose, granting it the hydrophobic character required. The liquid phase modification was made just with palmitoyl chloride, to perform this reaction was hard to find the conditions (not available information, no previous work) and many things to do to carry out the reaction, one of that was the exchange of solvent, from water to DMF; residual water and the size of the particles was the parameter to help to decide whether the exchange had worked. From the results we can say that the right temperature to accomplish this type of modification is 90 ° C and the time can change between 24 and 96hours, always taking care of the amount of pyridine to add. The gas phase modification was made with the five reactants, in all cases (except with maleic anhidride) the cellulose was modified. Was possible to find two reactants that just modify the surface of the crystal, sebacoyl chloride and ASA anhidride, the last one is environmentally friendly; in these cases the DSg was lower than DSsurface.

Nanomaterials are defined as materials in which at least one length dimension is below 100 nanometers. In this size regime, these materials exhibit particular - and tunable - optical, electrical or mechanical properties that are not present at the macro-scale. This opens up the possibility for a plethora of applications at the interface of materials, chemistry, physics and biology, many of which have already entered the commercial realm. When nanomaterials are blended with other materials not necessarily in the nanometer regime, the resulting nanocomposites can exhibit dramatically different properties than the bulk material alone, leading to an enhanced performance in terms of, for example, increased thermal and mechanical stability. This book presents the synthesis, characterization and applications of nanomaterials and nanocomposites, covering zero-dimensional, elemental nanoparticles, one-dimensional materials such as nanorods and nanowhiskers, two-dimensional materials such as graphene and boron nitride as well as three-dimensional materials such as fullerenes, polyhedral oligomers and zeolites, complemented by bio-based nanomaterials, e.g., cellulose, chitin, starch and proteins. Introductory chapters on the state-of-the-art of nanomaterial research and the chemistry and physics in nanoscience and nanotechnology round off the book.
