Parasitic helminths, despite their known negative impact (biomaterial) on human health and animal production, have fascinating features. In this study, we find fantastic magnetic properties in several forms: inductor [between 20.10 and 58.85 (±2.50) H], source of detectable electrical voltage [from +0.5 to 7.3 (±0.1) V, vs. the ground, GND, measured by an AVO meter] and different inductor magnitude [between 3.33 and 41.23 (±0.76)] μH, detected by electrochemical impedance spectroscopy as well as frequency scannable electromagnetic wave horn) in several frequencies (including 100, 120, Hz, and 1, 10, 100 kHz) in "Fasciola hepatica", "" (with and without larvae), " "", and " eggs. This claim is attributed to some surprising characteristics, including superior inductance and intrinsic magnetic susceptibility. This feature along with a close relationship to helminth egg structure, is a novel probe with acceptable reproducibility (RSD > 8.0%) and high enough trustworthiness for adequate differentiation in their magnitudes, relatively. These traits were measured by the "" methodology using a three-microelectrode system, implanted to each egg at the Giga ohm sealed condition (6.08 ± 0.22 GΩ cm, = 5). The reliability of these results was further confirmed using multiple calibrated instruments such as a high-resolution inductance analyzer, LCR meter, impedance spectrometer, potentiometer, and an anomalous Hall effect (Magnetic field density) sensor. In addition, the critical role played (Synergistic Effect) by water-like molecules as the intermediate medium, besides the partial influence of other compounds such as dissolved oxygen, are investigated qualitatively, and specific relation between these molecules and magnetic field creation in helminth eggs was proved. These intrinsic characteristics would provide novel facilitators for efficient arriving at the researchable bio-based magnetic biomaterials, besides innovative and real-time identification probes in the " fields.
寄生性蠕虫尽管对人类健康和动物生产有已知的负面影响(生物材料方面),但却具有迷人的特性。在本研究中,我们发现几种形式的奇妙磁性:电感[在20.10至58.85(±2.50)H之间]、可检测电压源[相对于地(GND),由AVO表测量,从+0.5至7.3(±0.1)V]以及不同的电感量[在3.33至41.23(±0.76)]μH之间,通过电化学阻抗谱以及频率可扫描电磁波喇叭在“肝片吸虫”、“(有幼虫和无幼虫)”、“”和“虫卵”的几个频率(包括100、120Hz以及1、10、100kHz)中检测到。这一特性归因于一些令人惊讶的特征,包括卓越的电感和固有磁化率。这一特性连同与蠕虫卵结构的密切关系,是一种具有可接受重现性(RSD>8.0%)且可信度足够高的新型探针,相对而言能够在其大小上进行充分区分。这些特性是通过使用三微电极系统的“”方法测量的,该系统在千兆欧姆密封条件(6.08±0.22GΩ·cm,=5)下植入每个虫卵。使用多种校准仪器如高分辨率电感分析仪、LCR表、阻抗谱仪、电位计和反常霍尔效应(磁场密度)传感器进一步证实了这些结果的可靠性。此外,定性研究了水样分子作为中间介质所起的关键作用(协同效应),以及其他化合物如溶解氧的部分影响,并证明了这些分子与蠕虫卵中磁场产生之间的特定关系。这些固有特性除了在“领域”提供创新和实时识别探针外,还将为高效获得基于生物的可研究磁性生物材料提供新的促进因素。
