Directed self-assembly of inorganic nanoparticles at air/liquid interfaces

Abstract: Inorganic nanoparticles (NPs) appear as the forefront functional structure in nanotechnology. The preparation of functional materials based on inorganic NPs requires their assembly onto well-defined structures. Within this context, self-assembly at air-liquid interfaces is probably the best candidate for a universal procedure for active materials composed of assembled NPs. The detailed in situ mechanism of the lateral self-assembly and vertical organization of NPs at air-liquid interfaces is still unknown desp… Show more

“…The comparatively higher signal‐to‐noise ratio of the UV/Vis reflection spectra of QD_F compared to those of QD_TOPO might arise from a larger aggregation at the air–liquid interface, see Figure S9 (Supporting Information). The aggregation of inorganic nanoparticles at the air–liquid interface led to micron‐sized domains of nanoparticles, resulting in a higher noise in the spectroscopic signal . Such domains were visualized by microscopy, as reported below.…”

“…The field induced rotation is rectified into translational motion only in the proximity of an interface, condition that is fulfilled in most of the systems of application. [58,59] The vesicles reach velocities larger than the ones measured when they are loaded with superparamagnetic spherical particles. In superparamagnetic beads the susceptibility at static field is isotropic, and the induced torque is mainly determined at low frequency by the possible existence of a permanent moments in the particle, and at high frequency by the complex susceptibility.…”

“…In the first approach, the fluid membranes respond linearly to the synchronous or asynchronous spinning motion of the confined nanowires, perturbing at the same time the fluid outside in a controlled manner. The field induced rotation is rectified into translational motion only in the proximity of an interface, condition that is fulfilled in most of the systems of application . The vesicles reach velocities larger than the ones measured when they are loaded with superparamagnetic spherical particles.…”

“…Ultra‐large ordered monolayer structure is crucial to offer a readily implemented solution for the challenges that are currently faced on the use of inorganic NPs in practical applications . So far, the self‐assembly at the air‐water interface has been shown to be a simple, low‐cost, and high‐throughput method to assemble NPs into 2D closely‐packed and periodic nanostructured arrays with a large scale . Both hydrophilic and hydrophobic inorganic particles are suitable for such a method.…”
