“…These results could be explained by the lower oleic acid amount we have used, with respect to other authors: for instance,Farridi-Majidi et al [25], who International Journal of Chemical Engineering used more oleic acid per unit MNP, found an increased encapsulation efficiency and also a larger particle size, an effect we tried to avoid.…”

An original technique, based on supercritical CO 2 and on the particles from gas saturated solution (PGSS) micronization method, was developed to obtain magnetically active lipid microparticles. Magnetite nanoparticles (MNPs) were encapsulated into triestearin and phosphatidylcholine mixtures to increase their biocompatibility for future applications in the fields of biomedical diagnostics and therapeutic medications. The lipid particles produced were characterized to determine size and size distribution, and to confirm the encapsulation of MNP. The mean size was in the range of 200-800 nm. The possibility to drive these magnetically active particles by an external magnet was demonstrated in a simple apparatus simulating a vessel of the circulatory system. The results obtained indicate that the modified PGSS technique is suitable to produce lipid microparticles with magnetic activity for possible use in medical applications.

Abstract. Nanoemulsions are increasingly being investigated for their fascinating capability of loading both hydrophobic and hydrophilic molecules while their stability is still an issue, being affected by various factors. In this study, to evaluate the dominant factors affecting the stability of nanoemulsions, artificial neural networks (ANNs) were implemented. Nanoemulsions of almond oil in water containing oleic acidcoated superparamagnetic iron oxide nanoparticles were prepared using a mixture of Tween 80 and Span 80 as surfactant system and ethanol as a co-surfactant. The ratio of transparency of the samples at 30 min and 7 days after preparation was taken as an indication of the stability of samples. Four independent variables, namely, concentration of nanoparticle, surfactant, oil, and alcohol were investigated to find their relations with the dependent variable (i.e., transparency ratio). Using ANNs modeling, it was concluded that the stability is affected by all variables, with all variables showing reverse effect on the stability beyond an optimum amount.

“…Quando revestidas de poliestireno (PS), as propriedades de superfície das nanopartículas magnéticas são preservadas reduzindo no sistema a formação de aglomerações, mudanças na geometria molecular, nem degradação devido a exposição ao meio fisiológico (MAHMOUDI et al, 2011;RAMOS, FORCADA, 2011). Além disso a baixa distribuição de tamanho e forma final que podem ser obtidas na partícula revestida de PS será importante para o tratamento médico (FARIDI-MAJIDI et al 2006). al., 2011).…”
