“…In addition to allowing the visualization of the synthesized particles and its distribution in vitro, cerium is a very interesting and undervalued material for skin-related applications. When combined in low concentrations with HAp, Ce 3+ ions confer antibacterial properties [ 51 ]. Several studies reported that Ce 3+ -substituted HAp has excellent microbial restriction against S. aureus , E. coli , and Lactobacillus pathogens [ 52 ].…”

“…Materiais que contêm prata têm propriedades antibacterianas, pois a prata pode impedir o crescimento de biofilme e a colonização bacteriana nas várias superfícies (Dubnika e Zalite, 2014). Propriedades antibacterianas são encontradas na hidroxiapatita contendo cério (Ce 3+ ), isso ocorre devido à sua ação antibacteriana, cuja ação biocida ocorre em baixas concentrações de cério com efeito prolongado contribuindo para prevenir infecções pós-operatórias principalmente em procedimentos cirúrgicos de implantes ou próteses (Santos et al, 2020). O íon fluoreto (F -) pode promover a nucleação do HAp e substituir OHno HAp para formar fluorapatita, que possui boa rigidez, alto módulo de elasticidade e dureza, pode ainda estimular a diferenciação de células-tronco mesenquimais em osteoblastos.…”

“…Assim, promove uma dispersão homogênea de metais em toda a rede de polímeros devido ao seu crescimento controlado. Posteriormente, a lenta decomposição da matriz polimérica permite maior controle sobre a formação do material (Santos et al, 2020). A figura 2 apresenta um resumo esquemático do processo Pechini.…”

“…208 This ratio is more important during the HAp synthesis because it determines the phase composition of the nal product. [209][210][211] Although their method is a little greener due to the use of vegetable wastes, incorporating calcium precursors from seashells, eggshells, and other sources would be more environmentally friendly compared to the commercial CaCl 2 .…”
