Patent number: 11260148Abstract: The method of making an implant consists on coating of a supporting structure (1) with synthetic hydroxyapatite by immersing the supporting structure (1) in a suspension (3) and triggering of a cavitation in a portion of the suspension (3) being in contact with the supporting structure (1). The suspension (3) is formed by a liquid external phase, advantageously water, and internal phase, i.e. particles of synthetic hydroxyapatite having an average particle size not exceeding 100 nm and containing structural water in an amount from 2 to 6% by weight. The implant is coated with the above described hydroxyapatite subjected to cavitation and a thickness of 50 nm to 1000 nm, advantageously 50 nm to 300 nm.Type: GrantFiled: May 5, 2016Date of Patent: March 1, 2022Assignee: INSTYTUT WYSOKICH CISNIEN POLSKIEJ AKADEMII NAUKInventors: Wojciech Swięszkowski, Tadeusz Chudoba, Sylwia Kuśnieruk, Aleksandra Kędzierska, Bartosz Woźniak, Julia Rogowska-Tylman, Dariusz Smoleń, Elzbieta Pietrzykowska, Witold Lojkowski, Jacek Wojnarowicz, Aharon Gedanken, Janis Locs, Vita Zalite, Mara Pilmane, Ilze Salma

Patent number: 10370789Abstract: We disclose a system for preparing antimicrobial surfaces, coated with metal oxide nanoparticles by means of a novel sonochemical method. These antibacterial surfaces are widely used in medical and other applications. The deposition of metal oxides known to possess antimicrobial activity, namely ZnO, MgO and CuO, can significantly extend the applications of textile fabrics, medical devices and other items and prolong the period of their use. By means of the novel sonochemical method disclosed here, uniform deposition of metal oxide nanoparticles is achieved simply.Type: GrantFiled: April 18, 2016Date of Patent: August 6, 2019Assignee: BAR ILAN UNIVERSITYInventors: Aharon Gedanken, Yeshayahu Nitzan, Ilana Perelshtein, Nina Perkas, Guy Applerot
