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.
Here are some ways nanomaterials are used in cancer treatment: [1] Nano-materials Aerosol Drug delivery systems: Nanoparticles can be loaded with anticancer drugs, improving drug solubility, stability, and targeted delivery to cancer cells. This enhances the drug's therapeutic effect while reducing side effects on healthy tissues. [2]
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.
Nanotechnology has also helped to personalize oncology for the detection, diagnosis, and treatment of cancer. It is now able to be tailored to each individual's tumor for better performance. They have found ways that they will be able to target a specific part of the body that is being affected by cancer.
The main obstacle in using RNAi technology for the treatment of cancer is protecting the RNAi. It is very fragile, quickly metabolized, and it has to efficiently be delivered to the target cells in vivo. This is why nanoparticles are being used.
Nanotubes can help with cancer treatment. They have been shown to be effective tumor killers in those with kidney or breast cancer. [4] [5] Multi-walled nanotubes are injected into a tumor and treated with a special type of laser that generates near-infrared radiation for around half a minute. These nanotubes vibrate in response to the laser ...
The treatment of cancer is possible only because of the scattering and absorption that occurs for plasmonics. Under scattering, the gold-plated nano-particles become visible to imaging processes that are tuned to the correct wavelength which is dependent upon the size and geometry of the particles.
The GDNP has released several publicly accessible papers on nanotechnology and development, including "Nanotechnology and the Poor: Opportunities and Risks - Closing the Gaps Within and Between Sectors of Society"; "Nanotechnology, Water, and Development"; and "Overview and Comparison of Conventional and Nano-Based Water Treatment Technologies".
