This study presents the effect of chitosan on the properties of zinc ferrite nanoparticles suitable for potential biomedical applications. The co-precipitation method is employed to fabricate these bio-composites that exhibit excellent microstructural properties. The X-ray diffractometer (XRD) analysis confirms the presence of a cubic spinel structure in the zinc ferrite-chitosan bio-composites, indicative of their crystalline nature. Scanning electron microscope (SEM) imaging revealed spherical particles with a size distribution below 100 nm, demonstrating the successful synthesis of homogenous nanosized particles. Fourier transform infrared spectroscopy (FTIR) spectroscopy analysis identifies the active functional groups within the bio-composites, providing valuable insights into the molecular structure and interactions present in the synthesized materials. The presence of chitosan is confirmed, highlighting its role in modifying the chemical composition and enhancing the biocompatibility of the samples. UV–vis absorption spectra analysis reveals that the samples exhibits absorbance within the visible range. Vibrating sample magnetometer (VSM) analysis demonstrates the superparamagnetic behavior of the samples. Remarkably, these formulated samples exhibit superparamagnetism with zero coercivity and a magnetization of ≈0.0125 emu g⁻¹ at 5 kOe when doped with chitosan. These properties are crucial for potential biomedical applications making it a promising candidate for various biomedical applications.

壳聚糖对铁氧体纳米粒子微观结构性能的影响

这项研究介绍了壳聚糖对适合潜在生物医学应用的铁酸锌纳米粒子性能的影响。采用共沉淀法来制造这些具有优异微观结构特性的生物复合材料。 X 射线衍射仪 (XRD) 分析证实铁氧体锌-壳聚糖生物复合材料中存在立方尖晶石结构，表明其结晶性质。扫描电子显微镜 (SEM) 成像显示尺寸分布低于 100 nm 的球形颗粒，证明均质纳米颗粒的成功合成。傅里叶变换红外光谱 (FTIR) 光谱分析可识别生物复合材料中的活性官能团，为合成材料中存在的分子结构和相互作用提供有价值的见解。壳聚糖的存在得到证实，突出了其在改变化学成分和增强样品生物相容性方面的作用。紫外可见吸收光谱分析表明样品在可见光范围内表现出吸光度。振动样品磁力计 (VSM) 分析展示了样品的超顺磁行为。值得注意的是，当掺杂壳聚糖时，这些配制的样品表现出超顺磁性，矫顽力为零，并且在 5 kOe 时磁化强度约为 0.0125 emu g ^-1 。这些特性对于潜在的生物医学应用至关重要，使其成为各种生物医学应用的有希望的候选者。
