Mitsui-7, heat-treated, and nitrogen-doped multi-walled carbon nanotubes elicit genotoxicity in human lung epithelial cells

Publikováno v: Particle and Fibre Toxicology, Vol 16, Iss 1, Pp 1-19 (2019)

Abstract Background The unique physicochemical properties of multi-walled carbon nanotubes (MWCNT) have led to many industrial applications. Due to their low density and small size, MWCNT are easily aerosolized in the workplace making respiratory exp

Biokinetic Evaluation of Contrast Media Loaded Carbon Nanotubes Using a Radiographic Device

Autor: Mieko Takasaka, Shinsuke Kobayashi, Yuki Usui, Hisao Haniu, Shuji Tsuruoka, Kaoru Aoki, Naoto Saito

Publikováno v: Toxics, Vol 9, Iss 12, p 331 (2021)

Considerable progress has been made in various fields of applied research on the use of carbon nanotubes (CNTs). Because CNTs are fibrous nanomaterials, biosafety of CNTs has been discussed. The biokinetic data of CNTs, such as using the radioisotope

Multi-walled carbon nanotubes (MWCNTs) are composed of multiple coaxially arranged graphene cylinders. MWCNTs range in diameter from 1 to over 100 nm depending on the number of constituting graphene cylinders. MWCNTs can be divided into two general s

We explore the temperature dependence of pressure-driven water permeation through membranes consisting of a vertically aligned double-walled carbon nanotube (VA DWCNT) array. The prepared membrane with CNT inner diameter of 3.9 nm exhibits no water p

Nanofluidics in CNTs is argumentative though it is theoretically calculated by various reports. It is because only a few of experimental reports are available, and the measured permeability is not so large as that suggested from the theoretical calcu
