In the present study, chitooligosaccharide (COS) and salicylic acid (SA) conjugates were synthesized using H2O2-induced grafting polymerization and oxidized alginate (OA) and gelatin hydrogels were fabricated using Schiff's base reaction. To confirm the synthesis and improved activity of the COS-SA ...
1A. Briefly, 3 mL of methanol was mixed with 0.5 mL of acetic acid under agitation for 5 min. 19.7 mg HAuCl4.3H2O and 7.7 mg GSH were added and mixed for 5 min. Freshly prepared sodium borohydride solution (1.5 mL at 20 mg mL−1) was dropwise added and ...
Furthermore, it has been known that compounds comprising vicinal hydroxyl groups can be oxidized with the help of suitable oxidants, in particular with periodic acid or salts of periodic acid, such as sodium metaperiodate, such that two aldehyde functions are formed by breaking the C—C bond on...
