Well it's a number of things.
A: Firstly nanotechnology can refer to something as simple as, say, children's lincoln logs on a nano scale. Many new medication delivery systems are nano tech, but the sophistication is in their construction at that scale, not what they can actually do.
B: What they can do requires precise laboratory control.
C: There are a few nanomachines, but consider the current level of robotic technology: Robots are extremely limited in there abilities, try making a really tiny one, you have to sacrifice a lot. Nano machines are currently about as sophisticated as wheels and gears. Each machine only capable of doing one incredibly simple task.
D: Nanocomputers do not exist yet, no computer no brain. Nano robots do not yet exist in any form I am aware of, current nano tech is analog.
E: Should they overcome these difficulties, I am not aware of any nano power sources to run them.
F: the afore mentioned legal difficulties before any such things can be used in human trials. That's not just a decade before those trials can begin, there is still as much as a decade of human trials before they could ever be approved. That means a fully functional nanorobot designed to fight all known forms of disease, if invented today, would not be used for up to two decades.
Is it a rainbow? Since everything is continuous and the light waves will randomly be placed, right at the edge, some of the spectrum will happen to fall on the black dot and get absorbed and others will happen to fall on the white and get reflected. They will not be organized perfectly so that each lump of rainbow light falls on solely on one side or the other. Maybe so, mabey not?
^ Uh no. Fine I'll say it.
Basically, the question is meaningless. Color is a property of objects, and not boundaries.
EDIT: Hehehehe! I feel so mischievous.
The boundary of the black is not the white. The boundary of the black is where black ends, not inclusive of white, and vice versa. The surface could have a hole instead of a spot and would have the same boundary. The spot could be by itself and still have the same boundary. There is no 'line' that differentiates the two - the two being different is what differentiates the two.
What are the current limitations for a wireless transfer of electricity to be possible on a large scale? e.g. Having one generator send electricity to all households in a town without wires.
