I have also used a single glass fibre (held in a small bead of plasticene or Blu-tak) dipped in a drop of clear adhesive (Durofix, Bostik etc) to pick up single grains down to about 20microns for XRD analysis by the Gandalfi Camera method followed by elemental analysis by SEM. The catch then is the speed required to moisten the fibre with a minimal amount of adhesive and get it attached to the specimen within the couple of seconds before the tiny drop of adhesive dries.
All has to be done under a microscope of course, and it needs a steady hand, but then so does any method of handling such small grains.
