Some special recognitions and awards are the followings: POSCO Chung-Am award (2011), KAIST Pioneer Award, (2012), NASA inventor award (2008), Top science stories Discover Magazine (2008), Future young scientist award from the Ministry of Education, Science and Technology (2007), Excellence in Teaching Award, KAIST (2010, 2011), and KAIST Award for Excellence in Collaboration (2013).  

　　 This presentation will discuss the emerging surface chemistry utilizing catechol and catecholamine.The catechol/catecholamine compounds have exhibited material-independent surface modification [1]. Utilizing this unprecedented property, we have developed various material-independent surface functionalization strategies such as hydroxyapatite formation [2], mammalian cell adhesion [3], superhydrophobic surface preparation [4-5], and nitric oxide storage [6], In this presentation, a new concept called micro-omnifluidic systems inspired by the mussel-inspired catecholamine adhesives, the silicification process inspired by diatom, and the lubrication properties from pitcher plant. The micro-omnifluidic system is able to be operated in organic solvents which are incompatible with poly(dimethyl siloxane) (PDMS). Furthermore, the micro-omnifluidic system utilizes gravitational force so that no syringe pumps are required for operation. Finally, this fluidic system is adsorption free increasing reusability of the device. [1] H. Lee et al. Science 2007, 318, 426-430 [2] J. Ryu et al. Adv. Funct. Mater. 2010, 20, 2132-39 [3] S. H.
