Bengt Kasemo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9658157
    Abstract: The invention concerns an arrangement comprising at least one sensor nanoparticle supporting Localized Surface Plasmon Resonance (LSPR), at least one sensing material and at least one separating layer which separates the at least one sensor nanoparticle from the at least one sensing material. The arrangement allows for indirect sensing studies of change in and on the surface of a sensing material or environment by the sensor nanoparticle. The arrangement may also be used for optical temperature measurements and calorimetry, optical differential scanning calorimetry (DSC), to study hydrogen storage, catalytic reactions or for NOx sensing.

  • Patent number: 8431034
    Abstract: The present invention relates to nanopore membranes, methods for manufacturing such nanopore membranes, and uses thereof. In the methods for manufacturing the membranes colloidal lithography is used, which results in production of nanosize pores in a short time and on a large scale. The nanopore membranes have a narrow size distribution and are randomly arranged. Furthermore, the inter-pore distance shows very little variation.

  • Publication number: 20100139420
    Abstract: The present invention relates to a nanocell, and method for manufacturing same, for holding small volumes of soft matter confined in a gap of order 1 micrometer or smaller and measurement systems using the same. The nanocell comprise: a first structure (3) with a substantially flat surface in one direction; a second structure (6) with a substantially flat surface in one direction; and at least one spacer (1, 2); wherein said substantially flat surface of each first and second structure face each other and are separated by the at least one spacer and the two surfaces and the spacer together define a volume (7) between them for holding said soft matter or fluid, and the distance defined by the spacer between said surfaces of the first and second structure is less than 1 micrometer; the volume between the surfaces of the first and second structures and the spacer is in the range between 1 femto liters and 1 micro liters.

  • Patent number: 6006589
    Abstract: A device and a process for measuring resonant frequency and dissipation factor of a piezoelectric resonator are presented. After exciting the resonator to oscillation, the driving power to the oscillator is turned off after the decay of the oscillation of the resonator is recorded and used to give a measure of at least one of the resonators properties, such as dissipation factor, changes in the dissipation factor, resonant frequency and changes in the resonant frequency.

  • Patent number: 5697997
    Abstract: A method for preparing implant surfaces using gas discharge plasma including conveying the implants to a vacuum chamber. The implants are treated with an inert gas plasma to remove existing surface contamination and oxide layers from the implant surfaces. The implants are treated with an oxidizing plasma or by means of thermal oxidation to reoxidizing the implant surfaces. The implant treatment steps are carried out in a closed space, including a controlled atmosphere and produce a highly accurate and reproducible microstructure, composition, purity, and sterility in the implants.

  • Patent number: 4712681
    Abstract: The invention relates to a method of packaging artificial implants in a sterile and contamination-free manner, comprising applying the implant inside a closable capsule made of the same material as the implant, thereafter enclosing the capsule in a hermetically sealable outer casing and sterilizing the package thus produced, and also to a package for performing the method.
