A research team in Korea has developed a material that may potentially replace color-shifting ink in prevention of forgery of bank notes, ID cards and so on. A team headed by Dr. Sang-seok Lee from the Functional Composite Material Research Center of the Korea Institute of Science and Technology(KIST) announced that it has successfully developed a technology to fabricate liquid crystals comprising several layers with a thickness comparable to that of a hair strand using hydrophilic and hydrophobic properties. The study was led by Kim Shin-Hyun, professor of chemical and biomolecular engineering at the Korea Advanced Institute of Science and Technology (KAIST).
