The dataset presented herewith is that of a research paper entitled “Sodium alginate/cuprous oxide composite materials with antibacterial properties: A Preliminary Study revealing the counteracting effects of oligosaccharides in the matrix”, authored by Reeba Thomas, Fengyi Wang, Wipa Suginta, Chien-Yi Chang, Fengwei Xie.

In this study, different hydrogel samples based on sodium alginate (SA), chitin or chitosan oligosaccharides (NACOS or COS), and cuprous oxide (Cu₂O) particles were prepared and their antimicrobial properties were assessed. The below table shows the formations of the different samples. The details of this research can be read from the paper.

Table1 Different samples and their formulations
Code	Composition	
SA	SA	
SA-Cu2O	SA/Cu₂O = 1:2 (w/w)	
SA-NACOS-Cu2O	SA/chitin oligosaccharide/Cu₂O = 1:1:2 (w/w)	
SA-COS-Cu2O	SA/chitosan oligosaccharide/Cu₂O = 1:1:2 (w/w)	
SA-NACOS	SA/chitin oligosaccharide = 1:1 (w/w)	
SA-COS	SA/chitosan oligosaccharide = 1:1 (w/w)
