Abstract:
According to the present invention, a process for treating cultured cells is provided, which comprises the steps of: a) providing planar, two-dimensional objects ("flakes"), wherein these objects comprise a material which, upon application of an extrinsic stimulus, is transferred from the planar state into a rolled state, b) providing cells on said flakes, and c) transferring the flakes from the planar state into a rolled state by application of said extrinsic stimulus.
Abstract:
The invention relates to a device for analyzing one or more samples for the presence, amount or identity of one ore more target molecules in the samples, comprising one or more capture sites whereby the device comprises a gas evolving means. The gas evolved by the gas evolving means moves unbound target molecules away from the capture site and therefore helps to increase the efficacy of the analysis.
Abstract:
To improve automation, especially in 2D gel electrophoresis of proteins, DNA etc., a separation device (1) has a physically activatable means for releasing surfactant,eg. SDS, into the gel fr SDS-PAGE. In one embodiment, surfactant-bound polymer is photolytically cleaved; in another, a barrier layer (30) is melted/destroyed to allow surfactant from reservoir (20) to reach the separation area (10). The barrier layer may comprise a novolac.
Abstract:
A method of producing a lenticular device for an autostereoscopic display apparatus comprises providing a substrate having a surface which corresponds in shape to a desired surface profile for the array of lenticular elements, and providing an optical layer mixture of an optically birefringent material and a polymer precursor over the substrate surface. The optical layer is exposed to a stimulus for polymerizing the polymer precursor to have at least a polymer surface layer, thereby enclosing the material between the polymerized material and the surface to define lenticular elements. This method allows a simple polymerization process, forming a single layer, to complete the LC cell formation in the desired lenticular array shape.
Abstract:
An electronic device (10) comprises a substrate (100) carrying a single electrode structure (120) and a plurality of electro-optical elements (140; 160,180). The plurality of electro-optical elements (140, 160, 180) at least includes a first electro-optical element (140) covering a first part of the electrode structure (120), the first electro-optical element (140) comprising a first electrooptical material with a first transmission/voltage response characteristic and a second electro-optical element (160) covering a second part of the electrode structure (120), the second electro-optical element (160) comprising a second electro-optical material with a second transmission/vokage response characteristic. Consequently, the various electro-optical elements (140; 160 180) can be individually controlled with a single electrode structure by applying variable voltages.
Abstract:
An active matrix display device has an optical layer (7,9,11) comprising a mixture of an electro-optical material and a polymer precursor. An upper surface of the active plate comprises an array of wells (70) such that the upper surface has higher (72) and lower regions, and the optical layer mixture is provided over the active plate. The optical layer is exposed to a stimulus for polymerizing the polymer precursor into a polymer layer constituted by a top surface (9) and by side walls (11), thereby enclosing the electro-optical material between the polymerized material and the active plate to define display pixels. Enclosed bodies of electro-optical material defining display pixels are thus provided over the lower regions. This method uses the processing of the active plate to define wells (70) which provide a height difference which can be used to provide alignment of enclosed display pixels cells. This avoids the need for an alignment mask during the deposition and exposure of the optical layer.In an embodiment of the invention,a layer (74) having affinity to the polymer precursor is provided on the higher regions in a stamping step before exposing the otical layer to the stilus.
