Abstract
Gold nanoparticles (AuNPs) are used as fundamental materials in chemical/biological sensor applications, such as the DNA-AuNPs complex system for colorimetric sensor. As a result, the immobilization of AuNPs on target substrates is an important issue. In this study, we investigated the deposition of AuNPs on an amine-derivatized silicon wafer by in-situ AFM. Liquid-AFM allows structural changes and reaction kinetics of biomaterials and organic/inorganic nanomaterials in liquid media to be analyzed in-situ. The results showed that AuNPs were immobilized on an aminefunctionalized silicon wafer within a period of 1.5 hr.
期刊介绍：
The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
