Filled Carbon Nanotubes: Promising Material for Applications

Carbon nanotubes (CNTs) were first filled with a number of metals starting in 1993 [...].

In my review paper [19], I summarize the main achievements in metal halogenide, metal chalcogenide, metal, and metallocene-filled SWCNT research.The data from the analysis of the kinetics and electronic properties of filled SWCNTs were reviewed.New methods of processing the spectroscopic data were developed.The dependence of chemical properties on the chemical nature of substances was discussed.The achievements in metallicity-sorted SWCNT filling were described.The correlations between the chemical and physical properties of introduced substances and outer SWCNTs were highlighted.
In a research paper [20], the authors studied in detail the applications of aminated graphene for the covalent conjugation of monoclonal antibodies.They applied X-ray photoelectron and absorption spectroscopies and electron microscopy to their investigations (Figure 1).Chemiresistive biosensors composed of aminated graphene and conjugated antibodies were made.The authors showed that there is a selective response towards IgM immunoglobulins with a low limit of detection (Figure 2).In the Special Issue entitled "Applications of Functionalized Carbon Nanomaterials: Advances and Perspectives", we focus on applications of chemically functionalized carbon nanomaterials such as carbon nanotubes, graphene, graphene nanoribbons, 2D heterostructures, fullerenes, and nanodiamonds.
