The present invention relates to an arrangement () for detection of a first resonance frequency (F), related to a mass (') loaded carrier means (), and to compare said first resonance frequency (F) with a second, as a reference used, resonance frequency (F), related to said carrier means (), by using frequency comparing and/or calculating means () to evaluate, by a noted frequency shift (F-F), a mass weight (&#x2032;). An array of individual carrier means () are arranged adjacent to each other, that one or more of said carrier means are allotted different second resonance frequencies, that received resonance frequencies (F) from said loaded carrier means are received and/or evaluated simultaneously, or at least essentially simultaneously, in a signal receiving and/or processing unit () and that said first resonance frequencies (F) are compared and/or calculated within said calculating means () with corresponding resonance frequencies (F) stored in said unit () in a memory () thereof.

Arrangement for detecting resonance frequency shifts

Method for manufacturing a mold tool (), devised for forming a structured nanoscale pattern on an object () and having a layer () which is anti-adhesive with regard to the object (). A stamp blank () is provided with a structured pattern () on a surface (). The patterned surface () is coated with a layer () of a metal, which has a stable oxidation number and can form a mechanically stable oxide film. The metal layer () is oxidized for forming of an oxide film (). The oxide film () is exposed to a reagent comprising molecule chains (), each of which has a linkage group () which bonds to the oxide film () by chemical bonding, wherein the molecule chains () either at the outset comprise at least a group () comprising fluorine, or in a subsequent step is provided with at least one such group ().

Mold for nano imprinting

A device is provided for transferring a pattern to an object. The device may be used for transferring a pattern, such as micro- or nanostructures, from a stamp to an object. In accordance with one embodiment, the device comprises a first contacting means with a receiving surface for the stamp and a second contacting means with a receiving surface for the object. The device may further include a pressing means that is adapted to operate at least one of the contacting means for contacting the stamp with the object. One of the contacting means may include a base and a holder. The holder has a first end which defines one of the receiving surfaces and a second opposite end which is pivotally connected to the base in such a manner that the stamp and the object are automatically placed in a parallel position when contacting each other.

Device for transferring a pattern to an object

A metal mold for use in a nano-imprinting process comprises a firmly adhering monomolecular non-sticking layer. The layer was obtained by subjecting the mold to a reaction with a fluoroalkyl compound having a mercapto group. As a result of said reaction, the layer comprises an organic sulfide of said metal.
