Review of advanced sensor devices employing nanoarchitectonics concepts
Beilstein J. Nanotechnol. 2019, 10, 2014–2030, doi:10.3762/bjnano.10.198
- monolayers [133][134], Langmuir–Blodgett films [135][136][137], and layer-by-layer assembly [138][139][140][141] on sensors and related devices is a key nanoarchitectonics step for sensor fabrication. For example, Furusawa et al. immobilized nickel-nitrilotriacetic acid within a self-assembled monolayer on

- pressures. Figure 2 shows SEM images of these Langmuir–Blodgett films. From the analysis of the SEM images, it appears that 30 mN·m−1 is the optimal transfer pressure in the sense of a more homogeneous MOF distribution and lower particle aggregation. Pressure values higher than 30 mN·m−1 lead to a worse MOF
- suspensions were prepared from dry powders using a Selecta Ultrasons 3000683 ultrasonic bath (30 min) and magnetic stirring at room temperature overnight. In all cases, the suspensions were also sonicated for 30 min before using them for Langmuir/Langmuir–Blodgett film preparation. Langmuir–Blodgett films
- range 0.025–0.11 mg·mL−1. ODP content in all suspensions is 0.8 µmol·mL−1. Note that relative ODP wt % changes because the mass amount of ODP for all the dispersions is the same but MOF concentration changes. SEM images of Langmuir–Blodgett films transferred at: (a) 25 mN·m−1, (b) 30 mN·m−1, (c) 35 mN·m

- ] and electric [12] fields have also been reported. Such methods depend on the inherent pinned magnetic moments and induced polarizability of the particles, respectively. Finally, interfacial techniques such as Langmuir–Blodgett films [13][14] and evaporation-induced self-assembly [15] have also been
Rigid multipodal platforms for metal surfaces
Beilstein J. Nanotechnol. 2016, 7, 374–405, doi:10.3762/bjnano.7.34
- form monomolecular layers between both electrodes. In many cases, either self-assembled monolayers (SAMs) [23] or Langmuir–Blodgett films (LB) [24][25] of organic molecules on a solid surface provide the order at the molecular level inside the junction to accomplish interface functionalization. The
Effects of electronic coupling and electrostatic potential on charge transport in carbon-based molecular electronic junctions

- of molecules oriented between two conductors, with charge transport through the molecular layer. The vast majority of existing junction structures are based on metal/molecule bonding such as the Au/thiol self-assembled monolayers [13][14][15][16][17][18][19][20][21], Langmuir–Blodgett films on metals
Controlled graphene oxide assembly on silver nanocube monolayers for SERS detection: dependence on nanocube packing procedure
Beilstein J. Nanotechnol. 2016, 7, 9–21, doi:10.3762/bjnano.7.2
- nanocubes layers fully covered with GO revealed the presence of a homogeneous, flexible and smooth GO sheet folding over the silver nanocubes and extending onto the bare surface. Preliminary SERS experiments on adenine showed a higher SERS enhancement factor for GO on Langmuir–Blodgett films of AgNCs with
- ± 0.5 °C (Haake thermostatic bath, Germany). Continuous spreading isotherms and hysteresis cycles were obtained using the same barrier speed of 20 mm min−1 in both directions. The reported results are the average of at least three independent measurements. Langmuir–Blodgett films were transferred, after
Surfactant-controlled composition and crystal structure of manganese(II) sulfide nanocrystals prepared by solvothermal synthesis
Beilstein J. Nanotechnol. 2015, 6, 2319–2329, doi:10.3762/bjnano.6.238
- resemble those of M2+ stearates. The occurrence of a splitting of ν(C=O) bands of StAc and stearates is reminiscent of the Davydov splitting occurring in highly ordered structures such as Langmuir–Blodgett films [43]. This suggests the formation of ordered layers on the NCs surface. Notably, the presence
