Today’s advances in man-made nanomaterials pose new and unprecedented risks to employees along the whole value chain. Airborne, inhalable fiber-shaped nanomaterials like carbon nanotubes (CNTs) and graphene nanoplatelets (GNPs) can pose asbestos-like health risks when inhaled. Today’s available aerosol measuring devices are not capable of discerning CNT from less harmful airborne particles like pollen, dust or carbon black from diesel exhaust. Our high-tech but easy to use detection system can monitor an individual’s long-term exposure to nanotubes in workplaces. It allows university labs, R&D departments, start-ups, fiber producers and any company using material containing CNTs to monitor every individual employee.
