Your question is about the properties of nanomaterials in general?
In terms of size, small size leads to an increase in surface area (preferably in loading drugs)
All the properties of nano are good and useful, but in terms of toxicity and the risks of exposure to them in the long term
Very few studies
And it has not been proven that it is not 100% toxic to any substance
If you are doing your research outside Iraq, I wish you success
But inside Iraq, I do not advise you, there is no safe environment, the simplest safety conditions are not available, such as a special non-cotton jacket or special glasses that are not permeable to nanomaterials or shoes that are not permeable as well
To this day, most researchers and supervisors do not know how to store or dispose of nanomaterials due to negligence or the lack of special containers (not paying attention to safety) The only important thing is to increase the number of researches and not pay attention to the risks of these small-sized materials, the possibility of penetration upon contact with the skin or inhalation or etc.
And there is no study on their long-term effect
I sent you a research on the properties of nanomaterials
Nanomaterials possess unique properties, including a high surface area to volume ratio, enhanced reactivity, and quantum effects, which significantly differ from bulk materials. These characteristics enable applications in various fields, such as medicine, electronics, and energy.
