Carboxymethyl starch as a reducing and capping agent in the hydrothermal synthesis of selenium nanostructures for use with 3D-printed hydrogel carrier

The hydrothermal method is a cost-effective and eco-friendly route for preparing various nanomaterials. It can utilize a capping agent, such as a polysaccharide, to govern and define the nanoparticle morphology. Elemental selenium nanostructures (spheres and rods) were synthesized and stabilized using a tailor-made carboxymethyl starch (CMS, degree of substitution = 0.3) under hydrothermal conditions. CMS is particularly convenient because it acts simultaneously as the capping and reducing agent, as verified by several analytical techniques, while the reaction relies entirely on green solvents. Furthermore, the effect of sodium selenite concentration, reaction time, and temperature on the nanoparticle size, morphology, microstructure, and chemical composition was investigated to identify the ideal synthesis conditions. A pilot experiment demonstrated the feasibility of implementing the synthesized nanoparticles into vat photopolymerization 3D-printed hydrogel carriers based on 2-hydroxy..., , , # Carboxymethyl starch as a reducing and capping agent in the hydrothermal synthesis of selenium nanostructures for use with 3D-printed hydrogel carrier

This Zip file comprises data present in the Main article. Most files are .csv files with the Figure number used in the main article.
A CIF file was taken from the COD (crystallography open Database) as a reference.

Each folder has the experimental data files used to get the interpretation in the main articles, such as Fig1-NMR data, which has three .csv files, one named \"final results.csv,\" which has two data sets outlined by black color box, one from the 1H NMR. Another is from the 13C NMR, where column G values and column Q values, which correspond to the particular chemical shifts, are used for calculating the degree of substitution of CMS, found from the Mnova software for NMR illustration.Another one is polysacc1HNMR.csv files comprising the 1H N...
