The present invention relates to a method and an apparatus for forming one or more compartments in a yield-stress fluid, wherein the one or more compartments can be one or more droplets. The yield-stress fluid is selected from polydimethylsiloxane, silicone oil, colloidal particles in water or oil, diblock or triblock copolymers in water or oil, microcellulose, xanthum gum, 0.1 wt % Carbopol and a combination thereof. The present invention is applicable for use in crystallisation, bioassays and chemical microreactors.

A method for fabricating quantum dots according to the present disclosure includes (a) synthesizing InP cores based on an aminophosphine type phosphorus (P) precursor, (b) size-sorting the InP cores, and (c) forming at least two shells on the size-sorted InP cores. In this instance, the size-sorting includes precipitating the InP cores with an addition of a dispersive solvent and a nondispersive solvent to the InP cores and separating the InP cores using a centrifugal separator, wherein the InP cores are separated in a descending order by size by performing iteration with a gradual increase in an amount of the nondispersive solvent.

The present invention pertains to a flow path structure body for forming self-assembling molecular particles. The flow path structure body has a base body and a flow path structure provided to the interior thereof, the flow path structure having a first introduction channel 10 and a second introduction channel 20 that are independent of one another on the upstream side of the flow path structure, and the introduction channels merging at a merging site. The flow path structure has a dilution flow path 40 that is bent three-dimensionally toward the downstream side of the merging site. The dilution flow path 40 has two or more Y structural elements 50 that protrude out in the Y direction and one or more Z structural elements 60 that protrude out in the Z direction within the dilution flow path, and at least two adjacent Y structural elements protrude out alternately in the Y direction. The present invention pertains to a method of producing self-assembling molecular particles, whereby a self-assembling molecule-containing solution and a dilution medium are supplied to the flow path structure body to form self-assembling molecular particles that have encapsulated a substance to be encapsulated. The present invention provides: a method of producing self-assembling molecular nanoparticles that enables precise control of the particle size of self-assembling molecular nanoparticles that have encapsulated an anionic molecule or the like at a high encapsulation rate; and a flow path structure body used for production.
