Abstract: The invention relates to methods for measuring conformational changes and self-assembly/aggregation of proteins, especially the formation of amyloid fibrils, using conjugated polyelectrolytes. The conjugate polyelectrolyte is exposed to the protein whereby the conjugated polyelectrolyte and the protein of interest interact, and a change of a property of the polyelectrolyte in response to conformational changes of the protein is observed. The detected change is used to determine different conformations of the protein, especially the formation of amyloid fibrils.

Abstract: A photovoltaic device optical system for enhanced light harvesting with a transparent layer of dielectric material having on one side an array of micro-lenses and on the opposite side a metal reflective film with an array of openings. The micro-lenses focus direct sunlight impinging thereon through the openings, to separate direct sunlight and diffuse sunlight. The photovoltaic device has a first photovoltaic cell system for the exploitation of the direct sunlight located in the opposite hemi-space of the micro-lenses array with respect to the plane of the openings array and a second photovoltaic cell system for the exploitation of diffuse sunlight, located in the same hemi-space containing the micro-lenses array with respect to the plane of the openings array.

Abstract: A patterned substrate for biosensing applications, wherein the pattern includes hydrophilic and hydrophobic areas, and selected ones of the areas include at least at least one reporter molecule, a property of which is detectable. A method of making a patterned substrate includes performing a stamping procedure to provide a pattern of hydrophilic and hydrophobic areas on a substrate of a suitable material. One step of the stamping procedure includes attaching at least one reporter molecule to at least selected ones of the areas, the fluorescence of the conjugated polyelectrolyte being detectable and which will change as a result of interaction with a biomolecule.

Abstract: A tool for biomedical surgery comprises an elongate tube-like structure which is insertable into a body lumen, a surgical tool, arranged on the elongate tube-like structure, and a layered polymer microactuator, arranged in or on the elongate tube-like structure, for inducing geometrical changes or movements to the surgical tool via an electrochemically induced change of volume of the layered polymer microactuator. The layered polymer microactuator is arranged for external electrical actuation.

Abstract: A complex between a conjugated polyelectrolyte, and one or more receptor molecules specific for a target biomolecule analyte, the polyelectrolyte and the receptor being non-covalently bound to each other, is usable as a probe for biomolecular interactions. It also relates to a method of determining selected properties of biomolecules. Thereby, a complex as above is exposed to a target biomolecule analyte whereby the analyte and the receptor interact, and a change of a property of the polyelectrolyte in response to the interaction between the receptor and the analyte is detected. The detected change is used to determine the selected property of the biomolecule.

Abstract: The invention relates to a method for manufacturing a micromachined structure to be at least partly released from a substrate surface. A surface contact area, over which structure and the said substrate surface are in surface contact with each other during the manufacturing step, is divided into at least a first and a second contact zone, the adhesiveness between the structure and the substrate being greater in the first contact zone than in the second contact zone. As a manufacturing step, or as a step subsequent to the manufacturing, the structure can be released from the substrate surface at least over said second contact zone. The completed structure may also be completely loose from the substrate. The invention is also directed to a micromachined structure manufactured according to the method.

Abstract: The invention relates to a method for the preparation of electronic and electro-optical components and circuits based on conducting polymers. One or more boundary surfaces in the component between a conducting polymer and another material are formed by melting of the conducting polymer.
