“…These findings also imply that, relative to newly generated specimens, some intrinsic properties of cubosomes alter after 24 hours of solvent and cubosome cohabitation. 70 In another investigation, Malheiros et al incorporated miltefosine (hexadecylphosphocholine, HePC), an anti-leishmanial drug, into PHYT-based cubosomes in a fully hydrated medium. At a HePC concentration of up to 3.5 mol%, the NPs displayed a bicontinuous Pn 3 m cubic phase structure, while at HePC concentrations above 7 mol%, both the Im 3 m and Pn 3 m cubic internal structures coexist, possibly suggesting that the Pn 3 m phase transition occurred at saturation.…”

“…13 In vitro inverse bicontinuous cubic phases have attracted significant attention due to their unique properties; 14 they are soft biocompatible structures that have a large surface area due to their interconnected water pore network. Therefore, inverse bicontinuous cubic structures have found uses as drug delivery platforms 15,16 and protein crystallisation systems 17,18 where amphiphile composition, 19 stereochemical purity, 20 water content, 21 charge of the system, 22 solvents, 23 pH, 24 pressure and temperature 25 can be altered to achieve a particular bicontinuous cubic spacegroup or bicontinuous cubic lattice parameter.…”

“…As amostras de cubossomos foram preparadas seguindo o protocolo Bottom up (BU) descrito na literatura (AKHLAGHI et al, 2016) e aprimorado pelo nosso grupo de pesquisa, devido a alta variabilidade do tamanho de partícula obtido por diferentes usuários. (LOTIERZO et al, 2020) (MALHEIROS et al, 2020 Este método é essencialmente baseado na dispersão de lipídio (que inicialmente está solubilizado em etanol) em excesso de água, na presença de F127 como estabilizador. No entanto, esta metodologia depende do uso de uma molécula de hidrótropo, como o etanol (LYNCH; SPICER, 2004), para solubilizar o lipídio, evitando assim o uso de alta energia mecânica externa para quebrar partículas grandes (conhecidas como fase bulk) em uma dispersão de partículas menores.…”

“…Devido às dificuldades iniciais de se incorporar a CNZ aos cubossomos, por conta da sua alta hidofobicidade, um segundo estudo surgiu dentro do projeto, a fim de estudar as interferências dos solventes orgânicos, que estavam sendo utilizados, na estrutura das nanopartículas (LOTIERZO et al, 2020). Os solventes utilizados foram escolhidos devido a sua versatilidade e ampla utilização.…”
