  • Patent number: 12059826
    Abstract: A method for manufacturing shaped polymers of surface-active macromolecules, in particular silk, is provided. The method is comprising the steps of: • a) depositing an aqueous solution of the surface-active macromolecules on a surface, wherein the aqueous solution of the surface-active macromolecules is deposited in the form of a droplet, and wherein the surface is a hydrophobic micropatterned surface adapted to prevent the aqueous solution from penetrating into the pattern and to receive the droplet of the aqueous solution of the surface-active macromolecules and retain its droplet state; and • b) forming shaped polymers of the surface-active macromolecules on the surface.

  • Publication number: 20230158490
    Abstract: The present invention is directed towards a microfluidic device comprising a first compartment comprising an inlet that is connectable to a fluidic control unit and a second compartment, wherein the first and second compartments are connected by a micrometer channel so as to allow fluid communication between the two compartments. The device also comprises an air-lock element in fluid communication with the second compartment and the air-lock element is configured so that in use the internal atmosphere of the device is sealed from the external atmosphere and so that when fluid is introduced or withdrawn from the first compartment via the inlet the air-lock element maintains an overall constant pressure within the device. The present invention is also directed towards a method of manufacturing the microfluidic device, a kit-of-parts comprising the microfluidic device and a method of using the microfluidic device for accommodating, growing, culturing, isolating, treating and/or processing cells.

  • Patent number: 10040944
    Abstract: Modification of polymer surface properties is disclosed by using a method comprising providing a liquid curable monomer formulation comprising a surface-active compound so that the surface active component is attracted to or repelled from at least a specific part of a master surface and is fixed in the polymer article upon curing. The method is carried out in one step and is thus simple and inexpensive to carry out.

  • Publication number: 20170351175
    Abstract: A synthetic paper is manufactured with a method comprising the steps of: a) providing at least two types of pho to-polymerizable monomers, b) exposing the volume to a three-dimensional light pattern to induce a polymerization reaction, and c) removing uncured monomer to create an open microstructure. The volume comprises at least one monomer comprising at least two thiol groups and at least one monomer comprising at least two carbon-carbon double bonds, where the ratio (r1) between the number of thiol groups and the number of carbon-carbon double bonds fulfils one of: 0.5?r1?0.9 and 1.1?r1?2. One advantage is that off stoichiometry creates an edge effect giving better defined boundaries between exposed and unexposed parts in the volume and giving a possibility to create thinner micro pillars. Another advantage is that it is easy to bind molecules to the surface to obtain desired surface properties.

  • Publication number: 20120174572
    Abstract: The present invention relates to methods for the batch fixation and electrical connection of pre-strained SMA wires on a microstructured substrate using electroplating, providing high bond strength and electrical connections in one processing step. The integration process here developed relies on conventional micro machining techniques and it provides an efficient solution to some problems that have hindered the widespread diffusion of bulk SMA to MEMS, such as the lack of cost-efficient integration methods of bulk SMA and the difficult electrical contacting of the actuator material at small scale. Also disclosed herein is a Joule-heated SMA wire actuator on silicon MEMS.

  • Publication number: 20070090314
    Abstract: The present invention discloses a microvalve for providing pneumatic-flow regulation suitable for use in microsystem applications that are operable using highly efficient actuation means for flow obstruction while being space efficient in design in a manner that is suitable for cost effective bullsk microfabrication. In an embodiment of the invention, the microvalve comprises a first substrate layer, a second layer disposed over the first substrate layer cooperating with the first substrate layer to form a channel through which the flow traverses and defines a direction of the flow. An obstruction element or knife gate is micromachined into the second layer such that it is pivotably attached and actuated with a bimorph actuator to displace the gate along a plane that is substantially perpendicular to the direction of the flow in order to controllably regulate the flow.
