RAT BLOOD PROFILE EVALUATION AFTER Fe3O4/CHITOSAN COLLOID INJECTION. The application of iron oxide (Fe3O4) magnetic nanoparticles in the biomedical field is still being explored, mainly related to its toxicity and side effects. This article reported results of the study aimed at analyzing the effect of chitosan-coated magnetic nanoparticles (NPM-C) on rat blood profiles. Magnetic colloid as much as 1 ml (concentration of 5 mg NPM-C / mL aquabidest) for 1 kG rat body weight was injected through intra-venous to the treated rat group (4 Wistar rats aged 6 months; weight ± 275 grams; male sex) while another four rats injected with sterile aquabidest used as a control group. The blood taking from each group of rats was carried out on 1 day before injection and several days after injection (days 1, 7, 14, 21, 28) through veins in the tail. To these blood samples, a series of blood profile analyzes is carried out including basic hematology, blood chemistry, and fragility of the erythrocyte membrane. The results of the analysis showed no significant differences between blood profiles after treatment and control, which indicated that chitosan-coated magnetic nanoparticles did not trigger cellular stress responses in the blood. The stability of blood magnetism analyzed by VSM (Vibrating Sample Magnetometer) also shows that magnetic nanoparticles are detected in the blood and tend to decrease in number with increasing time, so it is thought that these nanoparticles can be degraded or have been distributed into organs. These stable properties are analyzed due to an existence of chitosan coating around magnetic nanoparticles. Based on this study it can be concluded that up to the given concentration limit, iron oxide nanoparticles coated by chitosan are not toxic and have the potential to be used as drug carriers, MRI contrast agents, and other biomedical applications.

“…In this situation, the hysteresis loop is formed by fluctuating the applied external field, H, initially H = 0 ascending to +Hmax, decaying to H = 0, descending to -Hmax, then back to the beginning, repeating the same pattern as the first ascending magnetic field, which is through zero to +Hmax. For determining magnetic domain type, this loop has been proved to be very essential [9][10][11][12]. Hysteresis loop causes different magnetic domain type behaviours, as shown in Figure 1 and explained by Tauxe [10,11] regarding its three-plot curve characteristic behaviour.…”

In rock magnetism, Vibrating-Sample Magnetometer (VSM) data displays magnetic moment in specific magnetic field applied in descending and ascending magnitude, which results in a pattern called hysteresis loop. This loop characterizes different magnetic materials depending on its shape. In recent years, the usage of computer software to analyze hysteresis loop has become necessary due to its precision. Easily executable, intuitive, and user-friendly open-source programs for analyzing VSM data are still not widely available despite their necessary utilization. HYSGUITS was designed with this issue in mind to further improve the development of tools in this field. HYSGUITS is a Graphic User Interface (GUI) to analyze the hysteresis loop of VSM data. MATLAB is a suitable base for producing this GUI compared to other programming language due to its sophisticated features and clean data visualization. This software is able to visualize hysteresis loop in different ways, mainly through the difference of ascending with descending magnetization value and its 1st derivative. The GUI displays the graph as an interactive plot window which provides detailed observation on each data points, supported by features such as interpolation and smoothing. This article introduces of the functionalities of HYSGUITS and demonstrates its utilization with example use case.
