The Use of Pickering Emulsion for Mitigating Dye Leakage in Droplet Microfluidics
نویسندگان
چکیده
This work describes a strategy to mitigate the undesirable transport of small molecules among aqueous droplets immersed in fluorinated oil by replacing surfactant molecules with nanoparticles as emulsion stabilizers (Pickering emulsions). Amphiphilic silica particles were synthesized and redispersed in fluorinated solvents, and monodispersed picoliter aqueous drops were generated from flow-focusing devices. The drops were highly stable and transport of model dye molecules were significantly decreased at a time span of at least 24 hours.

Droplet-based microfluidics is increasingly used for biological applications, where the recovery of cells or particles after an experiment or assay is desirable. Here, we present an electro-demulsification chip which circumvents the use of harsh chemicals and multiple washing/centrifugation steps and offers a mild way for extracting cells and polymer particles into an aqueous phase from microfl...

متن کاملAgarose Droplet Microfluidics for Highly Parallel and Efficient Emulsion Pcr
An agarose droplet method was developed for highly parallel and efficient single copy emulsion PCR. By capitalizing on the unique thermal-sensitive sol-gel switching property of agarose, PCR is efficiently performed in agarose solution droplets, which is gelated to agarose beads after PCR to capture amplicons to maintain the monoclonality of each droplet. This method allows high throughput gene...
