What if there were Nanites that could eat gunpowder in bullets and literally scour the planet for weapons, knowingly when they were going to be misused. A sort of smart, bacteria-sized robots that could sniff out and destroy ammunition and nuclear warheads, as well as conventional explosives, even the blade of a knife in the wrong hands. Is this possible? Of course the creator of this technology, would have to have anti-Nano Ammo. But still hopefully the establishment of right and good, could actually eliminate killing through weapons.

That is called Bio Germ Warfare.
Think of a better way to kill peoples and some tax collecting agency will figure out how to exploit it.
There was profit in Detante, there is more profit in war.

First we have to wait for Wesley Crusher to be born, so he can invent the things. 22nd or 23rd century if memory serves.
Second: gunpowder hasn’ t been used in weapons for years. It produces too much smoke. Its hard to see what you’re shooting at through a dense cloud of smoke. Smoke also tells the enemy where YOU are.
Third: I’d worry more about the nannites being used as weapons to eat everything. That would be easier to build than a selective machine. Self-replicating nano-sized machines could devour the earth. This would be bad. Very Bad.
