TLDR
Imaging showed that nanotubes enter the systemic blood circulation and within 5 min begin to permeate through the renal glomerular filtration system into the bladder.Abstract:
Intravenously administered multi-walled carbon nanotubes, functionalized with DTPA and radiolabeled with Indium-111, were dynamically tracked in vivo using a microSingle Photon Emission Tomography scanner. Imaging showed that nanotubes enter the systemic blood circulation and within 5 min begin to permeate through the renal glomerular filtration system into the bladder.read more

TL;DR: A critical review of the biophysicochemical properties of various nanomaterials with emphasis on currently available toxicology data and methodologies for evaluating nanoparticle toxicity suggests that NPs may need to be sequestered into products so that the NPs are not released into the atmosphere during the product's life or during recycling.
Journal ArticleDOI
Current progress on the chemical modification of carbon nanotubes.
TL;DR: It is shown here how CNTs formed following Halogenation, followed by Direct Formation on Defect Sites, and the subsequent Encapsulation of Inorganic Substances led to the formation of CNT’s with Metal Nanoparticles.

Pulmonary Toxicity of Single-Wall Carbon Nanotubes in Mice 7 and 90 Days After Intratracheal Instillation
TL;DR: Results show that, for the test conditions described here and on an equal-weight basis, if carbon nanotubes reach the lungs, they are much more toxic than carbon black and can be more Toxic than quartz, which is considered a serious occupational health hazard in chronic inhalation exposures.

Enhanced flow in carbon nanotubes
TL;DR: It is shown that liquid flow through a membrane composed of an array of aligned carbon nanotubes is four to five orders of magnitude faster than would be predicted from conventional fluid-flow theory.
