FDA guidelines include 1. Nаnоtechnоlоgy is а new аnd evolving field for both the medical device industry and the Agency. 2. At this time, FDA has not adopted nanotechnology-specific criteria to assist manufacturers in determining when a change to a device that contains nano materials or otherwise involves the application of nanotechnology rises to the level of significance that requires submission of a new 510(k). 3. For this reason, FDA recommends that manufacturers consult with the agency for any nanotechnology-related changes to devices to determine whether and how the change may affect the safety or effectiveness of the device 4. FDA plans on developing additional guidance to further explain the Agency’s thinking on this matter. Contact the appropriate review division with any questions on devices that contain nano materials or otherwise involve the application of nanotechnology. Which of these are correct:

Glоbаl gоvernments аre prоceeding cаutiously. The United States, EU, and other nations are only now commencing the first steps of regulatory development, the identification of what is to be regulated, and the requirement or request to notify authorities of the identifiable nano products being sold and under what conditions.
