The processing of polyelectrolyte-covered magnetite nanoparticles in the form of nanostructured thin films

Nanostructured Fe3O4 satellite gold nanoparticles to improve biomolecular detection

“…The adsorption peaks indicate that the absorbance increased linearly with the number of Fe 3 O 4 @Au/PVS bilayers. This behavior was also observed for other LbL-fabricated films containing polyelectrolytes and nanoparticles [29,33].…”

“…In particular, the surface of Fe 3 O 4 @Au NPs provides enhanced chemical stability [23], and the biocompatibility and optical, magnetic, and catalytic properties of the surface can be readily fine-tuned [24]. Fe 3 O 4 @Au NPs have many potential applications in fields such as electrocatalysis [25], immunoassays [26], diagnosis [27], photothermal and magnetic thermal therapies [28], biomolecule separation, sensing, and biosensing [17,29].…”

Fabrication, Property, and Application of Lignin-Based Nanocomposites

“…In the LBL technique, ultrathin films are formed by assembling nanoparticles and polyelectrolytes onto specific solid substrates from their liquid solutions, and main features of the thin films are fully tunable by external deposition parameters [72,84,85]. Lignin is a kind of natural anionic polyelectrolytes [73], and it is a promising material for LBL self-assembly as building block due to its accessibility and low cost.…”

Hybrid Nanoscale Magnetic Composites

“…[8][9][10][11][12][13][14][15][16] This method provides the necessary control of inter-particle distances in order to tailor the nanocomposite's end properties.

“…Among the myriad of bottom-up approaches developed so far, the layer-by-layer (LbL) self assembly 6 is a costeffective technique that enables one the fabrication of multifunctional nanofilms, where molecules and nanoobjects of different chemical compositions are transferred and held together at the surface of a solid support by different types of intermolecular forces, such as ion-pairing, hydrogen bonding, dispersion forces, etc. [8][9][10][11][12][13][14][15][16] Polyelectrolytes are essential in these types of films, since they hinder nanocrystal agglomeration and also provide the mechanical and chemical stability of the nanocomposite material. 7 The LbL technique is easily performed and short-time consuming and the deposition process can be scaled-up by very simple automation frameworks.…”
