Question: how are your nano-crystals created?

Kate Nicholson answered on 13 Mar 2014:

Same way as regular ones only in much smaller pots! I make a solution of whatever I want to crystallise, then make it into tiny droplets about 10nm across by putting them in oil and soap mixture. This is just like in your washing up bowl where the soap traps the oil from the dishes into teeny droplets only in my case it’s the water on the inside! Next bit is either wait patiently, or stick them in the fridge for a little gentle encouragement. As the drops collide together they swap bits of material so the crystals can grow, bit by bit. Next I take a drop of the oil and put it on a grid (think like your kitchen sieve only with nano holes) then go look at it with an electron microscope. If all has gone as it should then I have tiny nano crystals of the sort I want.
