A technique for forming nanostructures including introducing a plurality of molecular-size scale and/or nanoscale building blocks to a region near a substrate and simultaneously scanning a pattern on the substrate with an energy beam, wherein the energy beam causes a change in at least one physical property of at least a portion of the building blocks, such that a probability of the portion of the building blocks adhering to the pattern scanned by the energy beam is increased, and wherein the building blocks adhere to the pattern to form the structure. The energy beam and at least a portion of the building blocks may interact by electrostatic interaction to form the structure.

Patterning of nanostructures

A technique for forming nanostructures including a definition of a charge pattern on a substrate and introduction of charged molecular scale sized building blocks (MSSBBs) to a region proximate the charge pattern so that the MSSBBs adhere to the charge pattern to form the feature.

An adjustable mold includes a distortable boundary, a flexible membrane, and a pressurizer, and method of use thereof. Pressure is applied to the flexible membrane, which causes the membrane to distort over the boundary. The shape of the boundary and the distortion of the flexible membrane control the optical characteristics of a lens resulting from the application and curing of a molding composition placed on the flexible membrane or to cast other items having variable shapes determined in part by the flexible membrane. In addition, a mold edge is used to allow casting in predetermined shapes, reducing need for grinding or edging. Visual and emission device calibration features used in conjunction with calibration reference images allow uniform selective distortion of the flexible membrane.

Electrically (and, possibly, mechanically) active patterns are applied using a colloidal suspension of nanoparticles that exhibit a desired electrical characteristic. The nanoparticles are surrounded by an insulative shells that may be removed by therefrom by application of energy (e.g., in the form of electromagnetic radiation or heat). The nanoparticle suspension is applied to a surface, forming a layer that is substantially insulative owing to the nanoparticle shells. The applied suspension is exposed to energy to remove the capping groups and fuse the particles into cohesion. If the nanoparticle suspension was deposited as a uniform film, the energy is applied in a desired pattern so that unexposed areas remain insulative while exposed areas exhibit the electrical behavior associated with the nanoparticles. If the nanoparticle suspension was deposited in a desired pattern, it may be uniformly exposed to energy. Additional layers may be applied in the same manner, one over the other, to form a multilayer device.
