This presentation will discuss the emerging surface chemistry utilizing catechol and catecholamine. The catechol/catecholamine compounds have exhibited material-independent surface modification . Utilizing this unprecedented property, we have developed various material-independent surface functionalization strategies such as hydroxyapatite formation , mammalian cell adhesion , superhydrophobic surface preparation [4-5], and nitric oxide storage , 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.
