Carbon Nano-Onions as Nontoxic and High-Fluorescence Bioimaging Agent in Food Chain—An <I>In Vivo</I> Study from Unicellular <I>E. coli</I> to Multicellular <I>C. elegans</I>

Nanocarbon–{[Na10(PrW10O36)]2·130H2O} composite to detect toxic food coloring dyes at nanolevel

“…On the other hand, the unique physical, chemical, spectral and optical properties of water-soluble carbon nano-onion (CNO) attracts to explore their use in composite materials for variety of applications in catalysis, biochemical sensors, engineering, and in bio-imaging (Sonkar et al 2012). Thus, making hybrid of carbon nano-onion with POM nanoparticles may combine the properties of two ideal functional nanomaterials to get a wide range of applications which will play an important role in the development of nanoscience and nanotechnology (Suárez-Guevara et al 2014).…”

Facile synthesis of electrochemically active Pt nanoparticle decorated carbon nano onions

“…10 The G/D peak intensity ratio has been used to determine the relative degree of disordered carbon and other structural imperfections in CNOs. 11 An average of the G/D ratios for each sample was calculated and displayed in Table 1. The G/D ratios for raw and purified CNOs were found to be 2.3 and 1.3, respectively, suggesting the highly graphitic nature of the samples.…”

Trophic transfer of silver nanoparticles from earthworms disrupts the locomotion of springtails (Collembola)

“…To date, however, few studies have evaluated the transfer of ticles [7][8][9][10], Ag nanoparticles [11], carbon nano-onions (CNOs) [12], CeO 2 [5], and La 2 O 3 nanoparticles [6]. Au nanoparticles are the most studied of these nanomaterials, with one research group focusing on plant to hornworm [7,8] and earthworm to bullfrog [9] trophic transfers.…”
