Chapter 1 – Introduction to boron nitride nanotubes: synthesis, properties, functionalization, and cutting

This chapter presents an introductory review on properties, synthesis, functionalization, and cutting of boron nitride nanotubes (BNNTs). First, the intriguing properties of BNNTs are highlighted in the perspective of their application in the biomedical field. Then, the developments on the synthesis of BNNTs are summarized. In particular, recent advancements in mass production of BNNTs are described. The quality, purity, and dispersion issues of BNNTs synthesized by various techniques are then analyzed and compared for their potential use in biomedical applications. Later section of the chapter is devoted to review the covalent and noncovalent functionalization of BNNTs with various biocompatible polymers. Their dispersibility and cutting in aqueous media are then finally discussed.
