- 1. Frontier Interfaces Group Laboratory
Research interests of Ahn Group include nano-to-macro scale molecular and supramolecular assemblies, surface engineering, and nanobiotechnology.
Toward fundamental knowledge, we investigate molecular-level interaction of chemical and biological materials. Both nanoscale experiments and dynamic simulations are valuable tools of our investigation. The role of interfacial water molecules in chemo-bio interactions is one of the key issues in our laboratory.
In applied regime, we develop rapid on-site detection devices for chemicals of environmental and safety issues, and ultra-sensitive label-free diagnostic sensors for DNAs, proteins, and cells. Our devotion aims at creation of essential technologies for the construction of internet-of-sensors. A recent example is to enable OLED materials to function biological recognition, for the first time.
Our group’s scientific contributions have been published in high-profile journals including Science, J. Am. Chem. Soc., Adv. Mater., Acc. Chem. Res., Nat. Commun., and others, as well as in international intellectual properties.

- 3. Nano-structured Organic Materials Research Laboratory
The Nano-structured Organic Materials Research Laboratory, under the supervision of Professor Joona Bang, carries out research on various block copolymers and their applications. We design monomers, polymerize them using various methods of polymerization such as RAFT polymerization, ATRP, anionic polymerization, ROP, and ROMP. These polymers are then processed to be used in various fields including block copolymer nanolithography, organic nanoparticles synthesis, epoxy toughening, quantum dots and anti-fouling materials. In addition to lab work, our lab also performs computational simulations based on field theory and a particle-based model to predict the behavior of macromolecules.

- 4. Nano Materials & Functional Thin Film Laboratory
Nano Materials & Functional Thin Film Lab under supervisor of Prof. Jinhan Cho has focused on the development of novel layer-by-layer (LbL) assembly approach as well as the fabrication of LbL-assembled thin film applications using various adsorption mechanism and surface chemistry. For this goal, all the graduate students in our research group are studying (1) the surface chemistry of polymers, (2) the synthesis and surface modification of metal (or metal oxide) nanoparticles and carbon-based materials (carbon nanotube and reduced graphene oxide), (3) the interface control through complementary interactions (electrostatic interaction, hydrogen-bonding, and covalent interactions), and (4) the device physics of thin film-based target applications. Up to date, our group have developed a variety of novel LbL-assembly approaches called as ligand exchange LbL, ligand addition LbL, amphiphilic LbL, small molecule-mediated LbL assembly. Recently, our group have developed the multifunctional colloids, the nonvolatile memory devices, the triboelectric devices, the supercapacitor, and the batteries that can exhibit the higher performance through our novel LbL assemblies.
- What is LbL assembly ?
LbL assembly method offers diverse opportunities to prepare organic/organic and/or organic/inorganic nanocomposite films with tailored optical, magnetic, biological and electrical properties. An important advantage of this method is that it enables the preparation of films with controlled thickness, composition and functionality on substrates of different size and shape. Additionally, various inorganic nanoparticles as well as organic components can be inserted within LbL films through complementary interactions (i.e., electrostatic, hydrogen-bonding, or covalent interaction).
- Research area of our group is as follows:
- Synthesis of nanomaterials
- Development of Novel LbL-assembly and nanocomposite multilayer films
- Thin film based-functional Colloids
- Nonvolatile memory devices
