Cobalt-zinc ferritemagnetic纳米粒子在空气中(CZF-MNPs) wereprepared environmentbyconventional co-precipitationmethodusingferric,锌与sodiumhydroxide和钴盐,溶液温度在80°C,涂有生物相容性Dimercaptosuccinic酸(DMSA)。Themorphologyof所需nanoparticleswas调查byTransmission ElectronMicroscopy (TEM)和裸和涂布纳米颗粒的平均尺寸是16 - 40 nm。的结构和晶体阶段CZF-MNPs决心byX-ray衍射(XRD),结果证实了单相尖晶石铁氧体的形成。Theaverageof微晶sizeswas calculatedabout 13 nmusingScherrerA’s公式扩大的最强烈的峰值(311)。9000年执行的sampleswere Magnetizationmeasurements uptomaximumfield oe在roomtemperature deviceAlternating梯度FieldMagnetometry (AGFM)。涂层的saturationmagnetization nanoparticleswas thanthebarenanoparticles少。此外,结果表明,DMSA涂布的saturationmagnetization byincreasingmolarity下降。红外光谱resultsof thesampleswereanalyzedinthefrequencyrange 400 - 4000 cm - 1,结果也证实XRDandformation ofCo-Zn ferritephase。这些光谱表明DMSA覆盖表面的纳米粒子的存在
