    • A nanotube based device for guiding a beam of x-rays, photons, or neutrons, includes a beam source and at least one nanotube. Each nanotube has an optical entrance positioned in a manner that a projection of the direction of the central axis at the optical entrance intersects with the beam source. Each nanotube may have an interior diameter that varies along the length of the nanotube. to point the entrances of a bundle of nanotubes toward a point-shaped beam source, the bundle can be grown as an array of multilayer nanotubes from a spherical growth plate. The clear aperture of the bundle is enhanced by providing a smaller number of wall layers of each nanotube near the growth plate than at a distance from the growth plate.
    • 用于引导X射线,光子或中子束的基于纳米管的装置包括束源和至少一个纳米管。 每个纳米管具有以使得在光学入口处的中心轴的方向的投影与光束源相交的方式定位的光学入口。 每个纳米管可具有沿纳米管长度变化的内径。 为了将一束纳米管的入口指向点状束源,该束可以从球形生长板作为多层纳米管的阵列生长。 通过在生长板附近提供比与生长板相距一定距离的每个纳米管的较小数量的壁层来增强束的透明孔。

    • A graphene biosensor is formed on an electrically insulating substrate with a single- layer graphene sheet arranged between two metallic electrodes. The graphene sheet is in electrical contact with the metallic electrodes. The graphene sheet has perforations creating edges in the graphene sheet. The perforations may be holes on a micrometer scale or in a nanometer scale. The biosensor can be configured as an ISFET. The graphene sheet may comprise affinity probes immobilized on the edges for attaching specific molecules to the graphene sheet. Several graphene sheets may be arranged in a microarray with different affinity probes on different graphene sheets. The sensor may also be arranged on the distal end of a catheter for in situ measurements in a body vessel.

    • A pulsed laser beam (16) engraves a groove pattern on substrate (18) of material relatively transparent to the laser beam. The grooves (20) of the pattern are filled with a filling material of different density or different electron density. The pattern of grooves filled with material of different density creates a spatial density modulation that forms the basic structure of various optical elements. By adjusting the flux density of the laser beam to exceed a material break-down threshold only in specific locations, the material ablation can be reduced to a diameter smaller than the diameter of the laser beam itself. The grooves fabricated in this manner can be filled with a deformable material under vacuum with subsequent exposure to air pressure or higher pressure. It is also possible to fill the grooves with nanoparticles of different density and secured by heat application or with a coating.
    • 脉冲激光束(16)在与激光束相对透明的材料的基板(18)上雕刻凹槽图案。 图案的凹槽(20)填充有不同密度或不同电子密度的填充材料。 用不同密度的材料填充的凹槽的图案形成了形成各种光学元件的基本结构的空间密度调制。 通过仅在特定位置调整激光束的磁通密度才能超过材料分解阈值,材料消融可以减小到小于激光束自身直径的直径。 以这种方式制造的槽可以在真空下用可变形材料填充,随后暴露于空气压力或更高的压力。 也可以用不同密度的纳米颗粒填充凹槽,并通过加热或涂层来固定。
