Pluronics Tetronics and other surfactants Mediated Synthesis of Nanomaterials their Properties and Applicability

Abstract

newline ABSTRACT newlineChapter 1 newlineThis chapter is appended to introduce the subject of research to the readers. This chapter started with introduction of nanotechnology including types of nanomaterials ,types of nanoparticles. In this chapter, the general discussion of pluronics and tetronics have been discussed. The brief review on formation of micelles by pluronics and teronics has been discussed. Different methods to synthesize Au NPs as well as magnetic nanoparticles has been introduced. The brief discussion on Gemini surfactants has been also included in this chapter. newlineChapter 2 newlineTwo broader categories of water soluble block polymers such as Pluronics and Tetronics has been used in order to study their complexation tendency with Au NPs. On the basis of their original structure, adsorption phenomena of solid-liquid interface linear block polymers pluronics showed stronger association as compare to star shaped tetronics. Pluronics and Tetronics both have comprising units of polyethylene oxide (PEO)-polypropylene oxide (PPO)-PEO. The comparative applicability of pluronics and tetronics has been studied by various characterization techniques such as UV visible, size, zeta potential, solution conductivity, and microscopic studies. The critical aggregation concentration (CAC) between the block polymers and Au NPs has been calculated quantitively. Since these results will be used for diverse applications in biological systems where AuNPs frequently used as markers or drug delivery systems. newlineChapter 3 newlineThis chapter explains the surface adsorption of Gemini surfactants on tiny Ag/Au nanoparticles (NPs) to understand the solid liquid interface adsorption as well as micelle formation by using surface plasmon resonance (SPR) of Au/Ag NPs as an indicator. It is also explained by this chapter that NP surface-adsorbed Gemini surfactant systems can be treated as models for bio-nanomaterials in biological applications. We demonstrate this by choosing a series of highly surface active Gemini surfactants whose micelle formation a
