A Universal Approach to Ultrasmall Magneto‐Fluorescent Nanohybrids

Abstract

Seeded emulsion polymerization is a powerful universal method to produce ultrasmall multifunctional magnetic nanohybrids. In a two-step procedure, iron oxide nanocrystals were initially encapsulated in a polystyrene (PS) shell and subsequently used as beads for a controlled assembly of elongated quantum dots/quantum rods (QDQRs). The synthesis of a continuous PS shell allows the whole construct to be fixed and the composition of the nanohybrid to be tuned. The fluorescence of the QDQRs and magnetism of iron oxide were perfectly preserved, as confirmed by single-particle investigation, fluorescence decay measurements, and relaxometry. Bio-functionalization of the hybrids was straightforward, involving copolymerization of appropriate affinity ligands as shown by immunoblot analysis. Additionally, the universality of this method was shown by the embedment of a broad scale of NPs.

Chiral MoS2 Quantum Dots: Dual‐Mode Detection Approaches for Avian Influenza Viruses

“…Over the last few years, nanohybrid materials have gained significant research interest, and various approaches to conjugate different materials in one nanostructure have been described, either in a direct synthesis manner or by the conjugation of separate nanomaterials. In particular, magnetochirofluorescent nanohybrids are favorable materials for diverse applications in biomedical field, that is, fluorescence sensing, fluorescence imaging, magnetic resonance imaging, and magnetic separation of target analytes . In this study, we applied a two‐step process to make magnetochirofluorescent nanohybrids through immunoreaction for avian influenza virus detection.…”

“…[1][2][3] Surfactants play an important role in the process which could obtain materials with more active surface areas or specific areas. Fusiform nano-architectures (FNA) enriched abundant unsaturated or dangling bonds have attracted considerable attention as ideal structure for various applications.…”

“…In case of the introduction of CTAB, the summation energy of O 2 , CTAB, and Te (0001) are -605.447 eV, higher than the summation energy of Te (0001) and OC (-605.838 eV) as well as the energy of OCT (-606.992 eV), which means that the Te (0001) can be oxidized easily in the presence of CTAB. A detailed comparison is shown in Scheme 2 with the total energies of O 2 , CTAB and Te (0001) as the benchmark (0 eV).The relative energies of the other states are shown in Scheme 2(2,3,4). Moreover, Te fusiform-structures cannot form…”

In Vivo Deep Tissue Fluorescence and Magnetic Imaging Employing Hybrid Nanostructures

“…[30][31][32] On the other hand, fluorescent NPs can act as deep tissue tracking and visualizing agents. 16,[33][34][35][36] Studies involving polymer-encapsulation strategies have presented excellent results for in vitro studies and the imaging of topical tumor grafts, 33,37,38 but so far in vivo experiments performing deep tissue imaging with HNSs have sparsely been reported. 39 The use of such HNSs for in vivo applications is restricted by the spectral range of LNPs used (visible-red), which limits their optical penetration depth into biological tissues.…”
