Abstract: Provided are methods of manufacturing microstructures, in which at least one viscous composition each containing at least one active ingredient is disposed directly or indirectly on a first substrate and/or a second substrate and the viscous composition(s) is elongated between the first and second substrates. The methods are simpler and more cost-effective.

Abstract: Provided are a method of manufacturing a solid microstructure capable of controlling multidrug release by mixing a biocompatible or biodegradable material with microparticles or nanoparticles and/or an emulsion as drug carriers and a solid microstructure structure manufactured using the same.
Abstract: There are provided a method of forming a solid microstructure, comprising: (a) preparing a viscous composition on a substrate; (b) contacting a contact protrusion of a lifting support with the viscous composition; (c) blowing air on the viscous composition to condensate and solidify the viscous composition; and (d) cutting the resultant material of step (c) to form the microstructure, and a solid microstructure prepared thereby. A solid microstructure may be manufactured, which can easily include drugs without denaturation or deactivation, has microscale diameters and sufficient effective length and hardness and is also sensitive to heat, and a solid microstructure with desired characteristics (for example, effective length, top diameter and hardness) may also be easily and quickly manufactured at a lower production cost.
