Abstract: Proposed are a core-satellite micelle containing a tetra-block copolymer and a preparation method thereof. The core-satellite micelle includes a core, a shell surrounding the core, and a plurality of satellite domains positioned inside the shell. The core-satellite micelle contains a tetra-block copolymer represented by Structural Formula 1 below. The shell includes a first-monomer first block A1 and a first-monomer second block A2, and the satellite domain includes a second-monomer first block B1 and a second-monomer second block B2. The core-satellite micelle is foiled through self-assembly of the tetra-block copolymer, thereby having a larger interfacial contact area than existing block-copolymer micelles. Therefore, the core-satellite micelle can be used in next-generation nanotechnology applications such as drug delivery systems, porous catalyst materials, and sensors. A1-B1-A2-B2   [Structural Formula 1] In Structural Formula 1, A1 is a first-monomer first block, B1 is a second-monomer first block, A2 is a first-monomer second block, and B2 is a second-monomer second block.

Abstract: Provided is a method of forming a micro/nanowire having a nanometer- to micrometer-sized diameter at predetermined positions of an object. The method includes: preparing a micro/nanopipette having a tip with an inner diameter which is substantially the same as the diameter of the micro/nanowire to be formed; filling the micro/nanopipette with a solution containing a micro/nanowire-forming material; brining the solution into contact with the object through the tip of the micro/nanopipette; and pulling the micro/nanopipette from the object at a pulling speed lower than or equal to a predetermined critical speed (νc) to obtain a micro/nanowire having substantially the same diameter as the inner diameter of the micro/nanopipette tip.

Abstract: Provided is a method of fabricating a micro/nanowire having a nanometer- to micrometer-sized diameter at predetermined positions on an object. The method comprises: preparing a micro/nanopipette having a tip with an inner diameter (dpt) which is substantially the same as the diameter of the micro/nanowire to be fabricated; filling the micro/nanopipette with a solution containing a micro/nanowire-forming material; bringing the solution into contact with the object through the tip of the micro/nanopipette; and pulling the micro/nanopipette apart from the object at a pulling speed lower than or equal to a predetermined critical pulling speed (vc) to fabricate a micro/nanowire having substantially the same diameter as the inner diameter of the micro/nanopipette tip (dpt). The critical pulling speed (vc) is defined by a maximum limit of the pulling speed at which the micro/nanowire to be fabricated has the same diameter as the inner diameter of the micro/nanopipette tip (dpt).
