Disclosed herein is a device (1) for generating a dispersion of a first phase in a second phase, the device comprising a first inlet (2) for supplying a first phase, which opens into a first chamber (4), a second inlet for supplying a second phase, opening into a second chamber and a dispersion outlet (6) for collecting the dispersion. Furthermore, the device comprises a membrane (7), which separates the first chamber (4) and the second chamber (5) and which comprises a first side (8) facing the first chamber (4) and a second side (9) facing the second chamber (5). The membrane (7) comprises multiple channels (10) extending from the first side (8) to the second side (9), providing a fluidic connection between the first chamber (4) and the second chamber (5). Each channel (10) comprises a channel inlet (11) arranged on the first side (8) mid a channel outlet 812) arranged on the second side (9). The first chamber (4) is typically configured such that a flow rate of the first phase through all of the individual channels (10) is essentially equal.

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 relates to extended release microparticles comprising a drug, and a preparation method therefor, and when the extended release microparticles comprising a drug are administered in order to replace conventional drugs that should be administered daily or monthly, the drug administration effect can be continuously maintained for one week to three months. In addition, the drug administration effect is maintained for a long time and, simultaneously, microparticles are prepared so as to have the average diameter of a fixed micro-size, and thus an effective drug concentration can be constantly maintained by controlling the release of the drug from the microparticles, and a foreign body sensation and pain can be reduced during drug administration since microparticles having a uniform size are included during application as an injectable drug.

Nano- to microscale liquid coacervate particles are provided. The liquid coacervate particles are produced by a process including stimulating a population of liquid droplets containing one or a mixture of components to induce a phase separation point of a first component, and maintaining stimulation at the phase separation point to form a coacervate domain of the first component within each of the droplets to form the liquid coacervate particles. The self-assembled nano, meso, micro and macro liquid coacervate particles and related coated substrates can have utility in drug delivery, bioanalytical systems, controlled cell culture, tissue engineering, biomanufacturing and drug discovery.
