The action that will most likely help the scientist study the particle's motion is that He needs to use quantum mechanics, not Newtonian mechanics because this is a nanotechnology product.
This refers to the branch of mechanics that has to do with the description of motion and the different concepts of quantization of energy
Hence, we can see that based on the fact that a scientist uses a new quantum dot to make a dye and uses Newton's laws, but he seems to be breaking the laws, so he needs to use quantum mechanics because this is a nanotechnology product.
