It is worth mentioning that bacterial cellulose has been modified for reasons other than its use in composites. For example, bacterial cellulose has been modified by nitrogen-containing plasma in order to improve its cell affinity, and thus increase its potential for use in biomedical applications [176]. This opens the door, not only for other uses for bacterial cellulose but also additional ways it can be modified.

Phospholipids are a diverse group of compounds they are fat derivatives in which one fatty acid has been replaced by a negatively charged phosphate group, and one of several nitrogen-containing molecules and an alcohol group. Phospholipids are vital constituents of all cell membranes. The most widespread phospholipid in the plasma is lecithin (phosphatidylcholine), which is synthesised in the liver. 

Unexpected elements in a plasma polymer often are due to the redeposition of ablated materials. The presence of nitrogen found in a plasma polymer of a monomer that does not contain nitrogen can be traced to contamination of the reactor, which has been used for plasma polymerization of nitrogen-containing monomers [1]. The ablation of electrode material has been utilized to create a graded metal-polymer and polymer-metal interfaces to obtain an excellent adhesion [2,3]. Ablation, therefore, could be utilized in a beneficial way in the engineering of interfaces if we know the nature of ablation and how to control it.
