Patent number: 11000627Abstract: The present invention relates to a process of treating an implant, comprising a step of treating the surface of the implant with at least one phosphonic acid compound or a pharmaceutically acceptable salt, ester or amide thereof under sonication at a temperature of about 50° C. to about 90° C. This process is highly advantageous in that it allows the formation of a monolayer of the phosphonic acid compound on the implant surface, having a particularly dense surface coverage which, in turn, results in an improved implant biocompatibility and improved osseointegration.Type: GrantFiled: February 13, 2017Date of Patent: May 11, 2021Assignee: NANO BRIDGING MOLECULES SAInventors: Sabrina Buchini, Richard Curno, Björn-Owe Aronsson, Péter Péchy

Patent number: 9460861Abstract: The present invention relates to modified surfaces. The surfaces comprise an inorganic material on which a phosphinic acid derivative is adsorbed. The phosphinic acid thus turns out to be a new anchoring group useful for surface derivatization. The invention has many applications for photoelectric conversion devices, batteries, capacitors, electrochromic displays, chemical sensors, biological sensors, light emitting diodes, electrodes, semiconductors, separation membranes, selective adsorbents, adsorbents for HPLC, catalysts, implants, nanoparticles, antiadhesives, and anticorrosion coatings, for example.Type: GrantFiled: June 30, 2014Date of Patent: October 4, 2016Assignee: Ecole Polytechnique Federale De Lausanne (EPFL)Inventors: Shaik Mohammad Zakeeruddin, Peter Pechy, Michael Graetzel
