摘要:
A structured substrate is described which is suitable for forming and hosting a crystal array, as well as associated methods for making and using such a structured substrate. The structured substrate is made by injection molding and has on one side a combination of macro- and micro-structured features. Each macro-structured feature comprises an edge that forms a perimeter around an enclosed area containing a large number of the micro-structured features. When a droplet of a solution containing molecules of interest and a solvent is deposited onto one of the enclosed areas such that it extends somewhat beyond the perimeter, the droplet slowly dries and shrinks through evaporation of the solvent, during which the edge acts to seed crystallization of the molecules, and the micro-structured features act to direct crystal growth from the seed into the enclosed area. The crystal thus forms over the whole of the enclosed area in a shape that conforms to the perimeter. Crystals of a desired size and shape can therefore be formed.

A method of manufacturing a device with a planar electrode structure, the method comprising: (a) forming a microfluidic channel on a substrate; (b) applying a primer layer to at least part of the microfluidic channel, (c) applying a conductive liquid to the microfluidic channel, the conductive liquid comprising electrically conductive particles dispersed in a carrier medium, the carrier medium including a solvent; (d) allowing the conductive liquid to flow throughout the microfluidic channel by capillary action to form the planar electrode structure; and (e) evaporating the solvent from the carrier medium, is described. Devices obtainable using the method and their applications are also described.
摘要:
A method for copy protection in which an audiovisual or audio data is divided into a plurality of portions. The plurality of portions is at least partly scrambled and prepared so as to be stored on a record carrier in the scrambled order. This is done so that a physical position on the record carrier, e.g., a sector of the record carrier, where a respective portions of the divided data is stored depends on the scrambled order.

A hologram comprises a holographic layer stack including a holographic layer, holographic structures being formed in the holographic layer, and a functional layer, wherein the functional layer is configured to change its optical properties when being exposed to an environmental influence, wherein the holographic layer and the functional layer are stacked. The hologram may be attached to a device, for example, an electric mobile device. Examples of the electric mobile device comprise a mobile phone, a personal digital assistant, an MP3 player, a camera, and a watch.

A microfluidic device includes a first substrate made of a first polymer material and a second substrate made of a second polymer material, the first and second substrates having respective bonding surfaces, at least one of the bonding surfaces having channel formations so that, when the bonding surfaces are bonded by surface deformation to one another, the bonded first and second substrates and the channel formations form at least part of a microfluidic channel network comprising a plurality of microfluidic channels, wherein one or more indicator pits, separate to the channel formations defining the microfluidic channel network, are formed in at least one of the bonding surfaces, so that surface deformation caused by the bonding process causes a change of configuration of the one or more indicator pits.
摘要:
A microfluidic device comprising in sequence first, second and third layers of plastics materials. A microfluidic circuit including a laterally extending microfluidic channel is formed at the interface between the first and second layers by surface structure in one or both of the first and second layers. A via is formed in the third layer for supplying or removing fluid to or from the microfluidic circuit. A conduit is formed in the second layer to provide fluid communication between the microfluidic channel and the via. A weld is formed at the interface between the second and third layers in a continuous closed path around the via and forms a fluid-tight seal for fluid flow between the via and the microfluidic circuit.

Method and device for supplying of a data set stored in a database to supply of a data set, e.g. the content of a copy protected audio CD, which is stored in a database, e.g. to a user PC on which said content of a copy protected audio CD cannot be accessed, the following steps are performed: receiving a serial code of a set of serial codes assigned to said data set, verifying of said received serial code, in case of a positive verification, accessing said data set correspond to said received and positively verified serial code from said database and outputting of at least parts of said accessed data.
摘要:
A method of producing a polymer part comprising the following steps: (a) incorporating a hydrophobic small molecule into the polymer before, during or after manufacture of the polymer part, the hydrophobic small molecule and the polymer being essentially inert to one another; and (b) annealing the polymer part to induce migration of the hydrophobic small molecules to a surface of the polymer part to provide that surface with a specified degree of hydrophobicity defined by the combination of the polymer and the hydrophobic small molecule; is described. Polymer parts made according to the method are also described.
