  • Patent number: 12596304
    Abstract: Silanol-containing organic-inorganic hybrid coatings on semiconductor substrates for forming patterns thereon. The present coatings can be produced by coating of semiconductor substrates with metal and silanol containing polyhydridosilsesquioxane resin solutions. Provided herein is also a method for patterning a metal and silanol containing polyhydridosilsesquioxane coated substrate with radiation of light at a specific wavelength, the method comprising the steps of irradiating a coated substrate along a selected pattern to form an irradiated structure with a region of irradiated coating and a region with un-irradiated coating and selectively developing the irradiated structure to remove a substantial portion of the un-irradiated coating to form a patterned substrate. The invention allows for obtaining a preselected silanol content polyhydridosilsesquioxane resin, and adjustment of the silanol content will make it possible to obtain a highly sensitive coating for application in EUV.

  • Publication number: 20250229102
    Abstract: Method of treating biological surfaces with electromagnetic radiation in the form of light of two different energy levels, a first light with photons having a majority energy in the range from 3.5 eV to 2.8 eV and a second light with photons having a majority energy in the range from 1.24 eV to 2.48 eV. The photons of the first light and the second light are simultaneously directed against the biological surface. The invention also contemplates the use of sensitizers in topical treatments of infections using the method. The treatment will achieve good tissue penetration. It makes it possible to give antibacterial treatment to different areas of pathogen at the same time as two or more different energy photons can target molecules in different areas.

  • Patent number: 12161719
    Abstract: Antibiotic for use in a method comprising systemically administering a photosensitive antibiotic to a subject having a microbial infection in a target tissue to provide a blood plasma concentration of the antibiotic in the subject; allowing the plasma or tissue concentration of the antibiotic increase to a predetermined level; and subjecting the target tissue to photodynamic therapy in order to increase the antimicrobial action of the antibiotic in the target tissue. With light activation the efficacy of the photosensitizer antibiotic can be enhanced, the spectrum of the microbial effect broadened and even an antiviral effect can be obtained. Generally, the present invention can be exploited when there is a need for enhancement of the local antimicrobial effect of antibiotics.
