The various embodiments herein provide super paramagnetic iron oxide nanoparticles (SPIONs). The SPIONs have a plurality of metallic coatings and plurality of polymeric gaps. The embodiments herein also provide a method of synthesizing the SPIONs with metallic rings and polymeric gaps. The metallic coatings form a ring like structure on the outer surface of the SPION. The SPION has a size of 13 nm. The ring has a thickness of 2-3 nm. The rings are one or more in number. The polymeric gaps have a thickness of 3-5 nm. The polymeric gaps are one or more in number. The method involves mixing the SPIONs with a plurality of polymers and then forming a metallic ring on the outer surface of the SPIONs. The SPIONs have anti-bacterial properties and stop a growth of bacterial biofilms. The SPIONs also have SERS properties.
这里的各种实施例提供了超顺磁性氧化铁纳米颗粒(SPIONs)。SPIONs具有多种金属涂层和多种聚合物间隙。此外,这里的实施例还提供了一种合成具有金属环和聚合物间隙的SPIONs的方法。金属涂层在SPION的外表面形成环状结构。SPION的尺寸为13纳米。环的厚度为2-3纳米。环的数量为一个或多个。聚合物间隙的厚度为3-5纳米。聚合物间隙的数量为一个或多个。该方法涉及将SPIONs与多种聚合物混合,然后在SPIONs的外表面形成金属环。SPIONs具有抗菌性能并阻止细菌生物膜的生长。SPIONs还具有SERS性能。
