    Abstract: An object of the present invention is to provide an anti-adhesive/anti-clogging and/or color marked/tinted micro-capillary tube (microtube), microneedle, or micropipette. Typically, the color/tint will be selected such that the tip of the microneedle or micropipette is in contrast (e.g., visually) to the biological material. The tint/color may be selected to contrast the stained biological material. In some aspects, the color mark comprises nanoparticles that are modified by adding a non-adhesive coating/material that minimizes protein adhesion/adsorption. The microtubes and/or micropipettes may be treated with an anti-clogging reagent and an anti-adhesive reagent to prevent or reduce clogging and adhesion of the micropipette or microneedle to biological materials. The microtubes and/or micropipettes may be formed using additive printing processes and additive manufacturing techniques or from micropipette and microneedle pullers.

    Abstract: A method of manufacturing a plurality of through-holes (132) in a layer of first material, for example for the manufacturing of a probe (100) comprising a tip containing a channel. To manufacture the through-holes (132) in a batch process,
    - a layer of first material is deposited on a wafer (200) comprising a plurality of pits (210)
    - a second layer is provided on the layer of first material, and the second layer is provided with a plurality of holes at central locations of the pits (210);
    - using the second layer as a shadow mask when depositing a third layer (240) at an angle, covering a part of the first material with said third material (240) at the central locations, and
    - etching the exposed parts of the first layer using the third layer (240) as a protective layer.

    Abstract: The present invention relates to a method of manufacturing a probe comprising a cantilever with a conduit. According to the invention, an etchant window is provided in a layer covering an elongated sacrificial conduit core that is to form the conduit. This allows for an etching process where the elongated sacrificial conduit core is etched away before all material of a substrate is etched away, the remaining material of the substrate material making the probe stronger without being in the way during use of the probe.

    Abstract: A micro-machined nozzle includes a substrate (12) having a hole (14) formed on a first side (12a) that extends partially through a thickness dimension of the substrate (12) and a nozzle orifice (16) formed on a second opposite side (12b) that communicates with the hole (14). The nozzle orifice (16) has at least a portion of its interior wall serrated. A method of fabricating a micro-machined nozzle includes the steps of etching a first side (12a) of a silicon substrate (12) to form a hole (14) that extends partially through a thickness dimension of the substrate (12) and etching a second opposite side (12b) of the silicon substrate (12) to form a serrated nozzle orifice (16) that communicates with the hole (14).
