Abstract The removal of environmental pollutants through adsorption by nanomaterials or nanocomposites has attracted great attention over the past few decades. In this work, a novel strategy that combined with Diels-Alder (DA) and multicomponent reactions has been developed to fabricate carbon nanotubes (CNT) based polymer composites and their potential utilization for removal of rare earth ions from wastewater. First, the amino groups were introduced on the CNT through the DA reaction between C...

Abstract In this work, a novel one-step method based on the aryl diazonium chemistry has been developed for the first time to synthesize benzenesulfonic-modified NDs (NDs-SO3H), which were used to remove methylene blue (MB) in dyestuff sewage. The particle morphology, structure, physicochemical characters of NDs and NDs-SO3H were examined through SEM, TEM, XPS, TGA and FT-IR. To further explore the adsorption application, the adsorption behavior of NDs and NDs-SO3H at different temperature, init...

Abstract Nanodiamond (ND) has been regarded as one of the most fascinating carbon nanomaterials for biomedical applications owing to its excellent physicochemical and biological properties. The biomedical application of ND-based materials mainly depends on its surface chemistry and properties, so the surface modification of ND is very important to improve its final biomedical application performance. In this work, a novel route for the surface modification of ND was developed via the combination...

Abstract A number of nanomaterials, such as silicon dioxide, graphene oxide, nano-diamond, etc. have been discovered and reported for various applications in recent years. The removal of environmental pollutants using nanomaterials should be one of the most important topics owing to their small size, high specific surface areas and catalytical properties. However, the removal capability of some nanomaterials is still need to improve for the lack of active adsorption sites. The surface modificati...

Superwetting membranes with responsive property have attracted heightened attention because of their fine-tunable surface wettability. However, their functional diversity is severely limited by the "black-or-white" wettability transition. Here, we develop a coating strategy to fabricate the multifunctional responsive superwetting membranes with SiO2/octadecylamine patterns. The adjustable patterns relating to the responsive region are the key factor for functional diversity. Specifically, the co...

Abstract Recently, polydopamine (PDA) has emerged as a popular material due to its striking properties. As a novel bio-inspired material, PDA can be easily formed in environmental conditions on virtually all kinds of inorganic and organic substrates. The abundant functional groups on PDA allow it to be a versatile platform for further loading of other components with desired functionalities. Along with its excellent performance in various fields, research interest and attention about PDA have si...

Abstract Highly sensitive and selective detection of specific DNA or metal ions based on sensor platform of dye-labeled single-stranded DNA (named as ssDNA) and functional materials has attracted great research interest over the past few decades. Herein, we reported for the first time that polydopamine (PDA) modified SiO2 nanoparticles (PDA-co-SiO2 NPs) could be severed as effective fluorescent quenchers for fabrication of fluorescent DNA sensor systems for detection of functional nuclear acids ...

Abstract The effective removal of environmental pollutants using nanomaterials and their composites has attracted great attention over the past few decades. Among them, carbon nanotubes (CNTs) have been extensively applied as adsorbents to remove various environmental pollutants for their small size, large surface areas and unique chemical structure. However, the adsorption performance of pristine CNTs is largely limited for their poor dispersibility and lack of functional groups. In this work, ...

Abstract Carbon nanotubes (CNTs) are a novel type of one-dimensional carbon nanomaterials that have been widely utilized for biomedical applications such as drug delivery, cancer photothermal treatment owing to their high surface area and unique interaction with cell membranes. However, their biomedical applications are still impeded by some drawbacks, including poor water dispersibility, lack of functional groups and toxicity. Therefore, surface modification of CNTs to overcome these issues sho...
