  • Fluorinated pickering emulsion
    Patent number: 11135586
    Abstract: Described here is a composition comprising amphiphilic silica nanoparticles, wherein the silica nanoparticles are partially fluorinated. Also described here is a method for droplet-based assay, comprising dispersing at least one aqueous droplet in a continuous fluorous phase in a microfluidic channel, wherein at least one amphiphilic silica nanoparticle is absorbed to the interface of the continuous fluorous phase and the aqueous droplet, and wherein the silica nanoparticle is partially fluorinated. Further described here is a method for droplet-based assay, comprising dispersing at least one aqueous phase droplet in a continuous fluorous phase in a microfluidic channel, wherein the continuous fluorous phase comprises at least one partially fluorinated amphiphilic particle adsorbed to an interface of the continuous fluorous phase and the aqueous phase droplet, and wherein the aqueous phase droplet comprises at least one hydrophilic polymer adsorbed to the amphiphilic particle at the interface.

  • Emulsion-based fermentation for accelerated gas substrate mass transfer
    Patent number: 10273510
    Abstract: Described here is a method for increasing the transfer of a gas substrate in microbial fermentation, comprising incubating an emulsion comprising an oil phase and an aqueous phase droplet dispersed in the oil phase, and supplying the gas substrate to the oil phase, wherein the aqueous phase droplet comprises a microorganism, and wherein the emulsion is stabilized by a surfactant or an amphiphilic particle that is adsorbed to an interface of the oil phase and the aqueous phase. Also described is an emulsion for microbial fermentation, comprises an oil phase and an aqueous phase droplet dispersed in the oil phase, wherein the aqueous phase droplet comprises a microorganism, wherein the emulsion comprises a gas substrate externally-supplied to the oil phase, and wherein the emulsion is stabilized by a surfactant or an amphiphilic particle that is adsorbed to an interface of the oil phase and the aqueous phase.
