Dear Peter, you want to fix starches particles of a few nanometers dimensions on a grid and then cover them with a glass ?

If you are interested in measuring chemical contaminants (silica, metals, ecc.), we can look at the spectroscopic signal of the laser-induced plasma. For understanding the structure is much more complex; maybe we could try by vaporizing the material at low laser fluences and observing the eroded surface via confocal microscopy (which we have in our laboratory). It is not necessary to work in a liquid enviroenment; we can ablate in air.Gabriele

Dear Peter,I have not well understood the problem you propose. The method that I described allows to produce nanoparticles by focusing a laser pulse on the surface of a target submerged in a liquid. The energy of the pulse results in the ablation of the target, forms a plasma which cools in the liquid environment producing the nanoparticles. I have not understand what you suggested with the starch granule. For what concerns the gel, I suppose that a part of the laser is absorbed in the gel itself. Nanoparticles would probably be formed by chemical elements composing the target and the polymers (carbon, nitrogen, oxygen..).What you think ?

Dear all,
I began working in the production of nanoparticles via Pulsed Laser Ablation in liquid environment. The method seems very interesting because NPs are "pure", devoid of surfactant agents and chemical precursors. I am interested in joining projects related to such a matter.
