Worldwide investment in nanotechnology increased from $432 million in 1997 to about $4.1 billion in 2005. [3]: 1–3 Because nanotechnology is a recent development, the health and safety effects of exposures to nanomaterials, and what levels of exposure may be acceptable, is not yet fully understood.
The environmental impact of nanotechnology is the possible effects that the use of nanotechnological materials and devices will have on the environment. [20] As nanotechnology is an emerging field, there is debate regarding to what extent industrial and commercial use of nanomaterials will affect organisms and ecosystems.
Nanotoxicology is the study of the toxicity of nanomaterials. [1] Because of quantum size effects and large surface area to volume ratio, nanomaterials have unique properties compared with their larger counterparts that affect their toxicity.
The United States National Nanotechnology Initiative involves 20 departments and independent agencies that focus on nanotechnology innovation and regulation in the United States. Projects and activities of NNI span from R&D to policy on environment and safety regulations of NMs.
Ethics of nanotechnology is the study of the ethical issues emerging from advances in nanotechnology and its impacts.. According to Andrew Chen, ethical concerns about nanotechnologies should include the possibility of their military applications, the dangers posed by self-replicant nanomachines, and their use for surveillance monitoring and tracking.

Nanotechnology has the potential to benefits all forms of work from daily life to medicine and biology. Despite these benefits, there are also health risks when it comes to human exposure to the nano material. Studies have shown that dangerous nano-particles can build up in the body after prolonged exposure.
Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale, surface area and quantum mechanical effects become important in describing properties of matter. This definition of nanotechnology includes all types of research and technologies that deal ...
A simulated particle collision in the LHC. The safety of high energy particle collisions was a topic of widespread discussion and topical interest during the time when the Relativistic Heavy Ion Collider (RHIC) and later the Large Hadron Collider (LHC)—currently the world's largest and most powerful particle accelerator—were being constructed and commissioned.
