“…37 The hydroxyl groups appeared at 3404 cm À1 (O-H stretching vibration) and 1622 cm À1 (O-H bending vibration), which included adsorbed water on the GO surface in air. 38,39 To confirm the presence of the oxygen-containing groups on the surface of GO, XPS measurements were conducted. From Figure 1b, the XPS analysis revealed that GO contains 27.8% oxygen, which can be related to the oxygen-containing groups discussed in detail below.…”

Graphene, a single layer of graphite, has recently attracted a large amount of attention because of its extremely high electronic and thermal properties, as many nanoscale materials are based on individual graphene. Graphene oxide (GO), which is the intermediate during the chemical processing of graphene, consists of graphene functionalized with oxygen-containing functional groups that imparts the desirable solution-processability to the neat graphene. Herein, poly(vinyl alcohol) (PVA), a hydrophilic polymer, was selected as the matrix, and PVA/GO nanocomposites were prepared by a simple and environment friendly process using water as the proceeding medium. In the PVA matrix, GO was exfoliated and nanodispersed. We found that the nanocomposites constructed by the incorporation of GO up to 1% by weight possess remarkable properties, such as significantly high mechanical and thermal properties. These excellent reinforcement effects were achieved not only by the rigid structure and high aspect ratio of the exfoliated GO but also by the strong interaction between PVA and GO. Furthermore, owing to the sheet-like structure of GO, the barrier properties of the nanocomposites were found to be dramatically increased.

Carbon-based nanomaterials have attracted much interest during the last decade for biomedical applications. Multimodal imaging probes based on carbon nano-onions (CNOs) have emerged as a platform for bioimaging because of their cell-penetration properties and minimal systemic toxicity. Here, we describe the covalent functionalization of CNOs with fluorescein and folic acid moieties for both imaging and targeting cancer cells. The modified CNOs display high brightness and photostability in aqueous solutions and their selective and rapid uptake in two different cancer cell lines without significant cytotoxicity was demonstrated. The localization of the functionalized CNOs in late-endosomes cell compartments was revealed by a correlative approach with confocal and transmission electron microscopy. Understanding the biological response of functionalized CNOs with the capability to target cancer cells and localize the nanoparticles in the cellular environment, will pave the way for the development of a new generation of imaging probes for future biomedical studies.

“…Annealing at 700°C in vacuum changed the zeta potential to a positive value of 34 mV. In the FTIR spectra, the peak at 1778 cm -1 of B corresponding to the CO stretching vibration of the carbonyl and/or carboxyl groups disappeared and the absorption at around 2900 cm -1 corresponding to CH 2 [12,[20][21][22][23][24] became pronounced after heating (Fig. 3).…”

A new facile method that employs high‐power sonication is used to break up firmly agglutinated nanodiamonds and obtain dispersion just as effectively as stirred‐media milling. The dispersion properties of the de‐agglutinated nanodiamonds in various nonaqueous solvents, and the pH‐dependent dispersion/precipitation behavior of the hydrosols are presented (see figure). The brownish color of the colloids is attributed mostly to the Rayleigh scattering superimposed over the finite absorption in the visible wavelength.
