Embossed and Intaglio Nano-Patterning using Nanopipette based on the QTF-AFM System

An S.M., Lee K.Y., Jhe W.H., Seoul National University, KR

We demonstrated embossed and intaglio nano-patterning using Nanopipette based on the QTF-AFM (Quartz Tunning Fork-Atomic Force Microscopy) system. Used materials in the patterning system were nanoparticles solution and acetone for delivery solution mica and flat [...]

Area Effect of Patterned CNTs Bundle on Field Emission Characteristics

Weng T.W., Lee K.Y., National Taiwan University of Science and Technology, TW

We show the relationship between the property of field electron emission, the area of patterned CNTs bundle, and the density of CNTs bundle. The current density can reach as high as 20 mA/cm2 at about [...]

Nano-structured Chitosan Self-Aggregates as a Drug Delivery Carrier

Bae M.S., Kwon I.C., Jeong S.Y., Lee K.Y., Hanyang University, KR

A number of novel delivery systems have been developed including the entrapment of drugs, proteins, antigens, or genes in small vesicles or within polymeric matrices. Colloidal delivery systems such as liposomes, microemulsions, and polymeric micelles [...]
