Regulated synthesis of an Au NB-DT@Ag bimetallic core-molecule–shell nanostructure for reliable SERS detection

“…Penta-twinned Au seeds were synthesized through a heatinduced twinning method. 42,43 Briey, 13.75 mL of water, 6.25 mL of CTAC stock solution, 200 mL of 0.5 M CA and 200 mL of HAuCl 4 stock solution were added to a scintillation vial (25 mL) in sequence under vigorous stirring at room temperature. Then, 500 mL of fresh NaBH 4 solution (25 mM) prepared in icecold water was added to the above yellow solution and kept under vigorous stirring for 3 min, aer which the resultant brown solution was heated under gentle stirring and kept at 100 °C for 2 h. Finally, the seed solution was cooled and stored at room temperature.…”

Synthesis and photocatalytic property of Au–TiO2 nanocomposites with controlled morphologies in microfluidic chips

“…[23][24][25][26][27][28] Moreover, controlling the thermodynamic and kinetic factors in the synthesis process has proven to be challenging, severely limiting the synthesis, yield, and reproducibility of hybrid structures. [29][30][31] Precisely controlled one-step synthesis and structure manipulation of plasmonic metalsemiconductor nanocomposites remain a significant challenge. Microfluidics is a powerful tool for manipulating fluids in miniaturized devices due to its precise control, high throughput, rapid mixing, and heat transfer capabilities.…”

Mixing Performance Analysis and Optimal Design of a Novel Passive Baffle Micromixer

“…The single-channel micromixer has the advantages of a simple structure, low processing cost, and small pressure drop, and is most widely used in passive micromixers [5]. Commonly used single-channel micromixers include T-type [6], Y-type [7], sawtooth-type [8], square-wave-type [9], curved-channel-type [10,11], spiral-channel-type [12] and twisted-channel-type [13] etc. Because the T-type micromixer has a large number of baffles, the fluid flow path is longer, the vortex intensity is stronger, and it has a better mixing efficiency.…”
