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.
