SEM/EDX analysis of the samples surface, together with information on chemical composition and the distribution of elements. Data underlying the research project "Gelatin-alginate hydrogels for hard-to-heal wounds" (GAlHyd)

This dataset contains data collected during investigation of hydrogels based on natural polymers (gelatin, sodium alginate), as part of the research project "Gelatin-alginate hydrogels for hard-to-heal wounds". The purpose of these experiments was to determine the chemical composition and the distribution of elements in samples of hydrogels saturated with an antiseptic (chlorhexidine digluconate).Prior to structure determination, micrographs were collected on several lyophilized hydrogel films with a JEOL JSM-6510LV scanning electron microscope (SEM). To obtain high quality micrographs, a thin gold film was sputtered with a JEOL JFC 1200 fine coater on samples randomly spread on a carbon tape. An OXFORD Energy Dispersive X-ray Spectrometer (EDS) coupled to the microscope was employed to verify the presence of Cl, Na, O, C and N elements and their spatial distributions within the crystals. The distribution of these elements is homogeneous, as shown in EDS elemental maps.

本数据集收录了"用于难治性伤口的明胶-海藻酸钠水凝胶（Gelatin-alginate hydrogels for hard-to-heal wounds）"研究项目中，针对天然聚合物基水凝胶（明胶、海藻酸钠）开展的调查实验所采集的数据。本系列实验的核心目标为测定负载消毒剂氯己定二葡萄糖酸盐（chlorhexidine digluconate）的水凝胶样品的化学组成及元素分布情况。在开展结构表征前，研究人员使用JEOL JSM-6510LV型扫描电子显微镜（SEM）对多份冻干水凝胶薄膜采集显微图像；为获得高质量成像效果，采用JEOL JFC 1200型精细镀膜仪，在随机铺展于碳胶带上的样品表面溅射一层超薄金膜。搭配该显微镜的OXFORD能量色散X射线光谱仪（EDS）被用于验证氯（Cl）、钠（Na）、氧（O）、碳（C）与氮（N）元素的存在，并分析其在晶体内部的空间分布；EDS元素分布图结果显示，上述元素的分布均一性良好。
