Abstract: A method for manufacturing an eco-friendly capsule includes: disposing a water phase material containing chitosan at a first site, and disposing an oil phase material at a second site and a third site, on a microfluidic chip; moving the water phase material and the oil phase material to a reaction site according to a predetermined flow ratio to produce an emulsion containing droplets having a predetermined diameter; mixing the emulsion with a water phase solution in a mixing tank; and producing chitosan beads by the reaction of the emulsion with the water phase solution.

Abstract: Disclosed is a method for diagnosing a target material by using a first substrate printed with a first nanoparticle. A second nanoparticle, which is bonded to a compound to be bound to the target material, is positioned at a distance adjacent to the first substrate.

Abstract: This invention relates to amphiphilic hydrogel particles for antifouling paint, which are environmentally friendly and in which anti-corrosion and antifouling effects can be maximized through a single coating process. The amphiphilic hydrogel particles are fabricated by encapsulating conducting polymer particles having anti-corrosion functionality with functional nanoparticles having antifouling functionality and then immobilizing the functional nanoparticles on a hydrogel matrix, whereby the conducting polymer particles contained in the functional nanoparticles are slowly and continuously released or the release rate thereof can be controlled so as to release the corresponding particles in a specific environment, ultimately maintaining long-term functionality. The conducting polymer particles contained in the amphiphilic functional nanoparticles can exhibit anti-corrosion functionality, thus maximizing anti-corrosion and antifouling effects through a single coating process.
