Additionally, their biological properties such as antioxidant, antibacterial, and DNA cleavage activities were determined. It is worth noting that, products 3 and 4 were newly synthesized structures. The antioxidant activities of all the nanomaterials 1, 2, 3, and 4 nanomaterials were investigated using some tests such as DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging and reducing power ability. Among the synthesized nanomaterials, product 2 exhibited the highest radical scavenging (64.8 +/- 1.94 %) and reducing power activity (0.61 +/- 0.017) at a concentration of 200 mg L-1. Product 4 was determined to have antibacterial activity against all three Gram-positive and three Gram-negative test bacteria. In addition, all the nanomaterials were tested for cleavage activity using pBR 322 plasmid DNA, as a result of which it was determined that only product 4 showed the ability of cleavage from both chains of DNA.eninfo:eu-repo/semantics/closedAccessAntioxidant activityDNA cleavage activityL-dopaNanomaterialsSilver NanoparticlesArticle61742174223Q3WOS:000656879800023Q32-s2.0-8510754158610.1002/slct.202004773
