摘要:
biocompatible gel comprising nanoparticles and / or nanoparticle aggregates; and kit comprising a biocompatible gel the present invention relates to compositions and methods for use in the diagnosis and medical monitoring of the patient, typically in the context of therapy, particularly in the context of oncology to optimize local irradiation of the tumor bed. and more particularly relates to a biocompatible gel comprising nanoparticles and / or nanoparticle aggregates, wherein i) the density of each nanoparticle and each nanoparticle aggregate is at least 7 g / cm3, the nanoparticle or nanoparticle aggregate comprising a inorganic material comprising at least one metal element having an atomic number z of at least 25, more preferably at least 40, each of said nanoparticles and each of said nanoparticle aggregates being covered with a biocompatible coating; (ii) the concentration of nanoparticles and / or nanoparticle aggregates is at least about 1% (w / w); and iii) the apparent viscosity at 2 s -1 of the gel comprising nanoparticles and / or nanoparticle aggregates is between about 0.1 ppm and about 1000 ppm when measured between 20 ° C and 37 ° C. 1/1resumo gel biocompatível compreendendo nanopartículas e/ou agregados de nanopartículas; e kit compreendendo um gel biocompatível a presente invenção se refere a composições e métodos para uso no diagnóstico e monitoramento médico do paciente, tipicamente no contexto de terapia, particularmente no contexto de oncologia para otimizar a irradiação local do leito tumoral. e mais particularmente se refere a um gel biocompatível compreendendo nanopartículas e/ou agregados de nanopartículas, em que i) a densidade de cada nanopartícula e de cada agregado de nanopartículas é de pelo menos 7 g/cm3, a nanopartícula ou agregado de nanopartículas compreendendo um material inorgânico que compreende pelo menos um elemento metálico que tem um número atômico z de pelo menos 25, mais preferencialmente de pelo menos 40, cada uma das di
