“…When a magnetic field was applied, the magnetic nanoparticles would collect the magnetic field and did not show magnetism after removal of the magnetic field [ 151 , 152 ]. It was found that the antimicrobial effect and inhibition time of the AMP Ib-M2 were improved through being encapsulated by SPIONs, which had implications for further study for targeted delivery of AMPs [ 62 ]. It was also shown that iron oxide nanoparticles (IONPs) could penetrate small capillaries in tissues and integrate into the natural metabolism of the body; they easily contacted with bacterial cells, and their antibacterial mechanism was the production of reactive oxygen, which could cause membrane disruption, protein damage, and DNA damage ( Figure 8 B) [ 153 , 154 ].…”

“…La síntesis de las IONPs se llevó a cabo mediante el método de coprecipitación [9] haciendo uso de cloruro de hierro tetrahidrato (II) (Sigma Aldrich, ≥99,0%), cloruro de hierro hexahidrato (III) (ACS, Reag. Ph Eur), hidróxido de amonio (NH 4 OH de Merck), quitosano (Sigma Aldrich, peso molecular medio), ácido acético glacial (Merck, 100%, Merck), N,Ndiisopropiletilamina (DIPEA, Sigma Aldrich, ≥99%), O-(benzotriazol-1il)-N,N,N',N′-tetrametiluronio tetrafluoroborato (TBTU, Sigma Aldrich, ≥98,0%), nitrógeno gaseoso de grado comercial (Praxair), y agua tipo 1 desionizada (18,2 MΩ•cm).…”
