- Millisecond-Timescale Monitoring of PbS Nanoparticle Nucleation and Growth Using Droplet-Based Microfluidics
Ioannis Lignos, Stavros Stavrakis, Ardita Kilaj and Andrew J. deMello
Article first published online: 21 MAY 2015 | DOI: 10.1002/smll.201500119
A droplet-based microfluidic system with integrated absorbance and fluorescence detection is used for the online screening of nucleation and growth of lead sulfide (PbS) nanoparticles at a millisecond time scale. The novel approach reveals the fundamental mechanisms, which govern PbS quantum dot formation at high temperatures and its adoption allows for high-throughput measurements gaining mechanistic understanding of various nanoparticle syntheses.

The preparation of 1D WS2 and MoS2 flexible nanoribbons by laser-induced unzipping of the nanotubes is reported. The nanoribbons are of high quality, uniform width, and devoid of surface contamination. The zig-zag edges in WS2 nanoribbons give rise to ferromagnetism at room temperature.

On page 2392, W. Hu, L. Liao, and co-workers report a large enhancement of the photoresponse in few-layer MoS2 phototransistors by coupling few-layer MoS2 with plasmonic nanostructures. Gold nanostructures, such as periodic nanoplates or randomly distributed nanoparticles, can excite localized surface plasmonic resonance waves under illumination, thus manipulating the direction of incident light propagation at a specific wavelength. In this manner, gold nanostructures can enhance the light-absorption efficiency as well as the photoresponsivity of MoS2 phototransistors.

A nanotechnology platform for highly parallel measurements is presented by N.-J. Cho and co-workers which monitors the interaction between membrane-active antiviral peptides and individual lipid vesicles. On page 2372, each vesicle is tethered to a passivated glass surface for highly specific detection. When the peptide forms a pore in the vesicle, fluorescent dye is released from inside the vesicle and the intensity change per vesicle can be followed in real time. Quantitative measurement capabilities enable comparison of various agents and are useful for drug development research.
