Multilayer Langmuir–Blodgett assemblies of hydrophobized CdS nanoparticles by organization at the air–water interface

Langmuir–Blodgett monolayers of InP quantum dots with short chain ligands

“…It has been demonstrated that surface-modified hydrophobic colloidal nanoparticles may be organized at the air-water interface, and that multilayer films of the nanoparticles can be formed on various substrates by this technique [10,11]. The LB technique has already been used by several groups to form films of materials such as gold [8], silver [12], CdS [13], and CdSe [3] QDs.…”

Formation of platinum nanoparticles at air–water interfaces by the spontaneous reduction of subphase chloroplatinate anions by hexadecylaniline Langmuir monolayers

“…A variety of methods are currently being developed to assemble nanoparticles in two-dimensional structures; they include self-assembly of the particles during solvent evaporation [1], immobilization by covalent attachment at the surfaces of self-assembled monolayers [2,3] or surfacemodified polymers [4]; electrophoretic assembly onto suitable substrates [5]; and DNA-mediated assembly in thin film form [6,7] and by diffusion into ionizable fatty lipid films [8]. Fendler and co-workers and subsequently other groups have recognized the utility of the air-water interface in the organization of hydrophobic, surfactant-stabilized nanoparticles and have shown that multilayer films of the nanoparticles can be deposited by the versatile LangmuirBlodgett (LB) technique [9][10][11][12][13][14]. Growth of multilayer nanoparticle films by the LB technique has also been shown to be possible through interaction of suitably derivatized colloidal particles from the subphase with the polar groups of the Langmuir monolayer [15][16][17][18][19].…”

Fabrication and surface transformation of FePt nanoparticle monolayer

“…Of these, LB technique of Au, Ag, CdS and Fe 2 O 3 , etc. nanoparticles have extensively been investigated for their potential application in nanodevices [6][7][8][9][10][11][12][13][14][15][16][17]. Recently, Lieber's group used this method to investigate the aggregates of semiconductor nanowires (NWs), and efficiently patterned by photolithography [18][19][20].…”
