Abstract:
The present invention relates to a polymer micelle-medicine complex based on a cellulose-graft-polylactide-based amphiphilic polymer and to a method for producing the same. More specifically, the polymer micelle-medicine complex includes an amphiphilic copolymer having a hydrophilic block including cellulose and a hydrophobic block including polylactide and is formed in a core-shell structure consisting of a hydrophobic core unit and a hydrophilic shell unit. Prednisolone acetate which is a refractory drug is encapsulated in the core unit of the core-shell structure so as to constitute the polymer micelle-medicine complex. The polymer micelle-medicine complex according to the present invention effectively solubilizes the refractory drug and changes the molecular variants of the amphiphilic copolymer so that a micelle having improved stability is produced. Accordingly, the encapsulation efficiency of the refractory drug is maximized and releasing behavior can be easily controlled.
Abstract:
The present invention relates to a device for forming homogeneous monomer droplets and, more specifically, to a device for forming homogeneous monomer droplets, which forms droplets with uniform shapes for making polymer particles in a bead type such as polystyrene beads, thereby improving uniformity in shapes and sizes of polymer beads. According to the present invention, the device collects a monomer solution with low viscosity at one point using a distribution plate and separately transfers the collected monomer solution to each droplet hole formed at a multi-hole distribution plate when the monomer solution is transferred, thereby forming monomer droplets with improved uniformity.
