Droplet-based Biogenic Paramagnetic Nanoparticle Synthesis
نویسندگان
چکیده
Droplet-based microfluidic system for biogenic paramagnetic nanoparticle synthesis is reported in this study. The engineered recombinant Escherichia coli (E. coli), which expressed heavy metal-binding proteins, were injected to droplets in the microchannel together with iron and manganese solution. Homogeneous droplets were generated and went through a serpentine channel to mix the three components efficiently. The droplets were collected from the outlet and incubated overnight at 37 °C. The synthesis of Fe-Mn paramagnetic nanoparticle inside E. coli was confirmed by detecting the movement of cells in the droplets induced by an external magnet, and was characterized by TEM.

We report the fast and sensitive trace analysis of diaquat dibromide monohydrate (DQ) in water using a surface-enhanced Raman scattering (SERS)-based microdroplet sensor. This sensor is composed of two compartments: the first one is for droplet generation for fresh silver nanoparticle (AgNP) synthesis and the second for droplet merging for SERS detection. Silver ions were nucleated and grown to...
