Supramolecular aggregates formed between polycyclic aromatic hydrocarbons and either naphthalene or perylene-derived diimides have been anchored in magnetite magnetic nanoparticles. The high affinity and stability of these aggregates allow them to capture and confine these extremely carcinogenic contaminants in a reduced space. In some cases, the high cohesion of these aggregates leads to the formation of magnetic microfibres of several microns in length, which can be isolated from the solution by the direct action of a magnet. Here we show a practical application of bioremediation aimed at the environmental decontamination of naphthalene, a very profuse contaminant, based on the uptake, sequestration, and acceleration of the biodegradation of the formed supramolecular aggregate, by the direct action of a bacterium of the lineage Roseobacter (biocompatible with nanostructured receptors and very widespread in marine environments) without providing more toxicity to the environment.
多环芳烃与萘或苝衍生的二酰亚胺之间形成的超分子聚集体已被锚定在磁铁矿磁性纳米颗粒中。这些聚集体具有高亲和力和稳定性，可将这些极具致癌性的污染物捕获并限制在较小的空间内。在某些情况下，这些聚集体的高内聚性导致形成几微米长的磁性微纤维，可以通过磁铁的直接作用从溶液中分离出来。在这里，我们展示了一种基于生物修复的实际应用，旨在通过直接作用于一种罗斯伯氏菌（与纳米结构受体生物相容，并且在海洋环境中非常普遍）来去除萘这种非常丰富的污染物，该方法可吸收、隔离和加速形成的超分子聚集体的生物降解，而不会对环境造成更大的毒性。
