Summary: This work focuses on the functionalization of SWCNTs and MWCNTs with two selected isoflavones and compares their physicochemical properties. Acidic treatment improved the dispersibility of both types of nanotubes, but SWCNTs still remained aggregated. However, MWCNTs showed increased dispersibility after acidic treatment. The functionalization with isoflavones was confirmed by improved dispersibility of the nanotubes.

Summary: This study aimed to determine the influence of single or multi-walled structures and surface functionalization on pulmonary toxicity of carbon nanotubes (CNTs) and to identify the underlying mechanisms. Mice were exposed to different doses of SWCNTs or MWCNTs, and inflammation and DNA damage were assessed. Transcriptomics analysis showed similar responses across all CNTs, with inflammation, cellular stress, metabolism, and DNA damage responses being affected. One pristine SWCNT was found to be the most potent and potentially fibrogenic, warranting further toxicity testing.

Summary: Functionalization of single-walled carbon nanotubes (SWNTs) using a series of bromoalkanes and dibromoalkanes with different tether lengths was investigated. Longer tether lengths (six or more) resulted in SWNT adducts with two new photoluminescence (PL) peaks, while shorter tether lengths (3-5) produced single peaks. The formation mechanism of functionalized adducts was found to be influenced by the tether length, with shorter tethers tending to produce kinetic products.

Summary: To achieve fast and sensitive detection of proteins, researchers have developed a polymer-sorted high-purity semiconducting carbon nanotubes (CNTs) films-based field-effect transistor (FET) biosensor for ultrasensitive and label-free detection of MUC1, a transmembrane protein highly expressed in breast cancer exosomes. The modified CNT FET was capable of sensitively and selectively detecting exosomal MUC1 as low as 0.34 fg/mL, and it could differentiate breast cancer patients from healthy individuals by comparing the expression level of exosomal MUC1. This novel CNT FET biosensor holds great potential for early diagnosis of cancer.

Summary: This work explores a novel approach to disperse purified double-walled carbon nanotubes in high ionic strength aqueous media, i.e. a copper ion solution, to further prepare double-walled carbon nanotubes/Cu composites by co-electrodeposition. The capability of different surfactants to disperse the carbon nanotubes in the copper ion solution is analyzed, and Pluronic-P123 shows the best dispersive level. The dispersion mechanism suggests that the hydrophobic nature of Pluronic-P123 promotes efficient steric repulsions, enabling stable dispersion in the copper electrolyte.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
