Patent number: 11712484Abstract: A method for generating vapour bubbles in an object comprises introducing a composition into the object, the composition comprising carbon-based nano- or microparticles that can couple with a photon wave of electromagnetic radiation. The method also comprises irradiating said object using electromagnetic radiation. The irradiation thereby is adapted for using a set of carbon-based nano- or microparticles for subsequently forming first vapour bubbles and at least second vapour bubbles using the same carbon-based nano- or microparticles.Type: GrantFiled: June 29, 2016Date of Patent: August 1, 2023Assignees: UNIVERSITEIT GENT, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE CNRS, UNIVERSITE DES SCIENCES ET TECHNOLOGIES DE LILLE 1Inventors: Kevin Braeckmans, Stefaan De Smedt, Joseph Demeester, Sangram Keshari Samal, Ranhua Xiong, Sabine Szunerits, Rabah Boukherroub
