“…Surface potential mapping of the surfaces functionalized with synthetic peptide assemblies were obtained using theEFM technique to distinguish purple membrane-peptide interactions at the interfaces [350]. EFM measurements were also performed to study theelectronic behaviour of the polymerizable unit conjugated peptide assemblies [43] and peptide-carbon nanotube hybrid architectures [351]. Within AFM-based approaches, Kelvin probe force microscopy (KPFM) [352] is used for the characterization ofpeptide assemblies to determine contact potential differences (CPD), which is related tothe work function of the samples.…”

Nature is an important inspirational source for scientists, and presents complex and elegant examples of adaptive and intelligent systems created by self-assembly. Significant effort has been devoted to understanding these sophisticated systems. The self-assembly process enables us to create supramolecular nanostructures with high order and complexity, and peptide-based self-assembling building blocks can serve as suitable platforms to construct nanostructures showing diverse features and applications. In this review, peptide-based supramolecular assemblies will be discussed in terms of their synthesis, design, characterization and application. Peptide nanostructures are categorized based on their chemical and physical properties and will be examined by rationalizing the influence of peptide design on the resulting morphology and the methods employed to characterize these high order complex systems. Moreover, the application of self-assembled peptide nanomaterials as functional materials in information technologies and environmental sciences will be reviewed by providing examples from recently published high-impact studies.

“…Pristine CNTs are very difficult to disperse in solution due to the formation of big bundles held strongly together by the van der Waals forces. In order to separate the nanotubes from self-aggregation, various dispersion agents such as ioniccomplementary peptides [38], biomolecules [39], surfactants [40], pyrene-containing polymers [41], and hyaluronic acid [42] as well as other natural polymers like gum Arabic, amylose, and Suwannee River natural organic matter [43] are used in order to achieve the desired dispersion effect.…”

The revolutionary development of functionalized carbon nanotubes (f-CNTs) for applications in nanomedicine has emerged as one of the most interesting fields, which has increased exponentially in recent years. This is due to their appealing physical and chemical properties, as well as their unique architecture. After a brief introduction on the physicochemical properties of carbon nanotubes (CNTs), we described several functionalization methods for the surface modification of CNTs, with the aim to facilitate their solubility in physiological aqueous environment. This review focuses on recent advances in drug delivery design based onf-CNTs with an emphasis on the determination of various parameters involved and characterization methods used in order to achieve higher therapeutic efficacy of targeted drug delivery. In particular, we will highlight a variety of different analytical techniques which can be used to characterize the elemental composition, chemical structure, and functional groups introduced onto the CNTs after surface modification. We also review the current progress of availablein vitrobiocompatibility assays based onf-CNTs and then discuss their toxicological profile and biodistribution for advanced drug delivery.

“…10 On the other hand, noncovalent functionalization involves the physical adsorption of surfactants, polymers, DNA, and peptides. [11][12][13] The noncovalent bonding of surfactants with CNTs is typically considered as a superior approach since it does not modify the p-electron network of CNTs and preserves their structural integrity. In addition, surfactants can be relatively easily removed aer treatment by washing.…”
