Tryptone

All chemicals used in this work are of analytical level. Peptide with the sequence of KIIIIKYWYAF was bought from the SynPeptide Biotechnology Co., Ltd. (Nanjing, China). Monolayered GO aqueous dispersions (GO-1, 10 mg/g) were provided by the Hangzhou Gaoxi Technology Co., Ltd. (Hangzhou, China). D-anhydrous glucose (AR), phosphoric acid, ethanol, glycerol, glutaraldehyde, NaCl, tryptone, and agar powder were purchased from the Shanghai Maclean Biochemical Technology Co., Ltd. (Shanghai, China).

Magnesium (Ⅱ) chloride hexahydrate (MgCl2·6H2O), scandium (Ⅲ) chloride hexahydrate (ScCl3·6H2O), and ammonium carbonate ((NH4)2CO3) purchased from Shanghai McLean Biochemical Technology Co., Ltd. (Shanghai, China) were used to prepare the nano-textured Sc2O3-MgO. 2-2-2-Trifluoroethanol (TFE, Analytical reagent) obtained from Aladdin Biochemical Technology Co., Ltd. (Shanghai, China) was used as spinning solvents. Polycaprolactone (PCL, 80,000) and polyvinyl pyrrolidone (PVP, K-30, 58,000) purchased from Baoqian Plastic Chemical Material Co., Ltd. (Hangzhou, China) and Aladdin Biochemical Technology Co., Ltd. (Shanghai, China) were used to prepare nanofibers. The bacteria used in this experiment was Escherichia coli (E. coli, ATCC 25,922, Shanghai Luwei Technology Co., Ltd. (Shanghai, China)). In addition, agar, tryptone, NaCl, and yeast extract powder purchased from Shanghai Maclean Biochemical Technology Co., Ltd. (Shanghai, China) were also used for the antibacterial tests. All reagents were analytically pure and were used without further processing or purification.
