This question supports and is linked to a fortified essay on the future of nanotechnology by Physical Chemist Kevin Ausman. Click here to read the full essay. There is a related question, whether nanoparticle-enabled cancer therapy will be approved by 2041, here.
Inorganic nanoparticles are small collections of a few thousand to a few billion atoms, typically ranging from 1 to 100 nm in diameter. They have many peculiar chemical and physical properties, which make them attractive for designing therapies.
Will an inorganic nanoparticle-enabled cancer therapy be approved by the FDA before 2031?
This resolves when the FDA gives full approval to a cancer therapy that uses inorganic nanoparticles in the patient's treatment. The therapy must target the cancer cells rather than downstream symptoms. We specify "inorganic" to exclude lipid nanoparticles etc.
