SUPPLEMENTARY INFORMATION: 

Nanotechnology is generally defined as 

the intentional manipulation of matter 

to form novel structures with one or 

more dimension or features less than 

100 nanometers (nm). Nanotechnology 

involves a wide range of chemistries 

and almost unlimited types of structures 

that have highly unpredictable 

interactions with biological systems. 

Carbon nanotubes (CNTs) are a type of 

nanomaterial comprised of a sheet of 

graphite (a hexagonal lattice of carbon) 

rolled into a cylinder that can have a 

length-to-width ratio greater than 1,000. 

Carbon nanotubes are produced having 

a single cylinder carbon wall (singlewalled carbon nanotubes [SWCNT]) or 

having multiple walls-cylinders nested 

within other cylinders (multi-walled 

carbon nanotubes [MWCNT]). CNTs 

range in diameter from about 1–2 

nanometers for SWCNTs to dozens of 

nanometers for MWCNTs with lengths 

extending into the micrometer range. 

There are several major techniques 

used in the synthesis of CNTs. The arcevaporation technique involves passing 

a current of about 50 A between two 

graphite electrodes in an atmosphere of 

helium in the presence of metal 

catalysts (Co, Ni). The second method is 

chemical vapor deposition, where 

nanotubes are formed by decomposition 

of a carbon-containing gas with use of 

nano-sized catalytic particles usually 

Fe, Co, Yt or Ni. The advantage of 

catalytic synthesis over arc-evaporation 

is the ability to scale-up for volume 

production. The third method for 

making CNTs, laser ablation, involves 

employment of a powerful laser to 

vaporize metal (Co and Ni)-graphite 

targets. Of the three major processes, 

chemical vapor deposition is the most 

prominent one that is currently used for 

CNT production. 

Due to their unique physical and 

chemical properties, CNTs have sparked 

much research into developing novel 

applications. CNTs are ideal nonbiodegradable materials; they are 

stronger then steel, flexible, lightweight, 

heat resistant, and have high electrical 

conductivity. The market for CNTs is 

estimated to grow substantially over the 

next decade. They are currently used in 

a variety of applications including: 

Electronics, reinforced plastics, microfabrication conjugated polymer 

activators, biosensors, enhanced 

electron/scanning microscopy imaging 

techniques, and in pharmaceutical/ 

biomedical devices for drug delivery 

and medical diagnostics. Estimates of 

the number of workers potentially 

exposed to CNTs are unavailable due to 

limited exposure data and its relatively 

recent introduction into domestic 

commerce. 

The toxic nature of SWCNTs and 

MWCNTs in humans is not known. 

Recently published in vitro and in vivo 

studies with some SWCNTs and 

MWCNTs describe adverse effects 

including their ability to be cytotoxic 

when tested in various cell cultures, and 

cause acute inflammation and early 

onset of fibrosis when delivered to the 

lungs of mice by pharyngeal aspiration 

or inhalation. No occupational exposure 

limits for CNTs have been established 

by NIOSH or the Occupational Safety 

and Health Administration (OSHA). 

NIOSH seeks to obtain materials, 

including published and unpublished 

reports and research findings, to 

evaluate the possible health risks of 

occupational exposure to CNTs. 

Examples of requested information 

include, but not limited to, the 

following: (1) Identification of 

industries or occupations in which 

exposures to CNTs may occur. 

(2) Trends in the production and use 

of CNTs. 

(3) Description of work tasks and 

scenarios with a potential for exposure 

to CNTs. 

(4) Workplace exposure measurement 

data in various types of industries and 

jobs. 

(5) Case reports or other health 

information demonstrating potential 

health effects in workers exposed to 

CNTs. 

(6) Research findings from in vitro 

and in vivo toxicity studies.
