Abstract: The present invention relates to a patterning method for producing optical displays and electronic/electro-optical devices based on quantum dots. By means of the invention, a pixelated multi-colored display containing quantum dots with no significant contamination can be produced, and quantum dots can be selectively patterned in targeted microscopic fields on an optical surface, with very little contamination.

Abstract: The present invention relates to a device for determining the mass of a nanoparticle, virus or protein in a suspension or solution in a fluid. This device can be applied in particular to mass spectrometry for ionized species with high collection efficiency (i.e. low limit of detection). According to the present invention, an instrument comprises a first device for electrospraying the fluid to obtain a charged flux comprising at least the particle, a second device for determining the mass of the particle by a frequency measurement and a third device that is fabricated on the same chip with, and surrounding the second device to focus and guide the majority of the incoming charged particles including at least the particle by means of holding charge on itself to act as an electrostatic lens.
