Functionalized surfaces based on polymers and carbon nanotubes for some biomedical and optoelectronic applications

Abstract

It has been long recognized that surface properties are of paramount importance for a broad range of materials and a large variety of devices. The recent development of nanoscience and nanotechnology has opened up novel fundamental and applied frontiers in surface functionalization and characterization. At the nanometre scale, the high surface-to-volume ratio characteristic of most nanomaterials has been demonstrated to have a tremendous influence of many fundamental material properties and device performance. In this paper, we present some of the important issues on the surface functionalization and characterization of polymers and carbon nanotubes for certain biomedical and optoelectronic applications and summarize our recent research activities along this line.

Hydrothermal technology for nanotechnology

“…In recent years functionalized surfaces based on CNTs and polymers, DNA-assisted dispersion and separation of CNTs and some special biomedical and optoelectronic applications have been prepared [193,194]. Hydrothermal technique has been effectively used to synthesize such nanocomposites.…”

Synthesis of MWCNT-COOH-Cysteamine composite and its application for dye removal

“…CNTs are divided into two types: (1) single-walled CNTs (SWCNTs) and (2) multi-walled CNTs (MWCNTs) [24,25]. CNT walls are not reactive, but their fullerene-like tips are known to be more reactive, so edge functionalization of CNTs is relatively used to generate the functional groups (e.g., − COOH, − OH, or -CO) [26].…”

Adsorption of Insulin Peptide on Charged Single‐Walled Carbon Nanotubes: Significant Role of Ordered Water Molecules

“…[1] They have rapidly become one of the most widely studied nanomaterials, primarily due to their fascinating structures and unique physicochemical properties. [2,3] The applications of SWNTs in biotechnology fields, such as biomaterials, [4] biosensor development, [5,6] biomedical devices [7] and cellular delivery of peptides and proteins [8,9] have recently started to emerge, raising great hopes. Although the lack of solubility of carbon nanotubes (CNTs) in aqueous media limits their application in bionanosystems, recently both covalent [10] and noncovalent [11] functionalizations have brought great opportunities for biological and biomedical applications.…”
