Abstract
The synthesis of nanoparticles has become a matter of great interest in recent times due to their various advantageous properties and applications in a variety of fields. The exploitation of different plant materials for the biosynthesis of nanoparticles is considered a green technology because it does not involve any harmful chemicals. In this study, iron oxide nanoparticles (Fe3O4-NPs) were synthesized using a rapid, single step and completely green biosynthetic method by reduction of ferric chloride solution with brown seaweed (BS, Sargassum muticum) water extract containing sulphated polysaccharides as a main factor which acts as reducing agent and efficient stabilizer. The structural and properties of the Fe3O4-NPs were investigated by X-ray diffraction, Fourier transform infrared spectroscopy, field emission scanning electron microscopy (FESEM), energy dispersive X-ray fluorescence spectrometry (EDXRF), vibrating sample magnetometry (VSM) and transmission electron microscopy. The average particle diameter as determined by TEM was found to be 18 ± 4 nm. X-ray diffraction showed that the nanoparticles are crystalline in nature, with a cubic shape. The nanoparticles synthesized through this biosynthesis method can potentially useful in various applications.
A síntese de nanopartículas tornou-se objeto de grande interesse nos últimos tempos devido às suas diversas propriedades vantajosas e aplicações em uma variedade de áreas. A utilização de diferentes materiais vegetais para a biossíntese de nanopartículas é considerada uma tecnologia verde por não envolver substâncias químicas nocivas. Neste estudo, nanopartículas de óxido de ferro (Fe3O4-NPs) foram sintetizadas por meio de um método biossintético rápido, em etapa única e totalmente verde, pela redução de uma solução de cloreto férrico com extrato aquoso de alga marrom (BS, Sargassum muticum) contendo polissacarídeos sulfatados como o principal componente atuante como agente redutor e estabilizante eficiente. A estrutura e as propriedades das Fe3O4-NPs foram investigadas por difração de raios X, espectroscopia no infravermelho por transformada de Fourier, microscopia eletrônica de varredura por emissão de campo (FESEM), espectrometria de fluorescência de raios X por dispersão de energia (EDXRF), magnetometria de amostra vibrante (VSM) e microscopia eletrônica de transmissão. O diâmetro médio das partículas determinado por TEM foi de 18 ± 4 nm. A difração de raios X evidenciou que as nanopartículas são de natureza cristalina, com formato cúbico. As nanopartículas sintetizadas por meio deste método de biossíntese apresentam potencial para serem úteis em diversas aplicações.
