Conductive AFM Patterning on Oligo(ethylene glycol)-Terminated Alkyl Monolayers on Silicon Substrates: Proposed Mechanism and Fabrication of Avidin Patterns

Autor: Chi Ming Yam, Zhongdang Xiao, Kai Liu, Jianhua Gu, Guoting Qin, Chengzhi Cai

Publikováno v: Langmuir. 27:6987-6994

Micro- and nanopatterns of biomolecules on inert, ultrathin platforms on nonoxidized silicon are ideal interfaces between silicon-based microelectronics and biological systems. We report here the local oxidation nanolithography with conductive atomic

Structure and Wettability of Methoxy-Terminated Self-Assembled Monolayers on Gold

Autor: Chi Ming Yam, T. Randall Lee, David Barriet, Irmgard Wenzl

Publikováno v: Langmuir. 19:10217-10224

This manuscript describes the structure and wettability of self-assembled monolayers (SAMs) derived from the adsorption of a series of ω-methoxyalkanethiols (CH3O(CH2)nSH, where n = 9−14) onto the surface of gold. Using ellipsometry, polarization

Preparation, Characterization, and Heck Reaction of Multidentate Thiolate Films on Gold Surfaces

Autor: Chi Ming Yam, Jaeeock Cho, Chengzhi Cai

Publikováno v: Langmuir. 19:6862-6868

Multidentate thiolate films were prepared by solution phase deposition of dendritic oligothiols on gold surfaces. The dendritic molecules contain three (G0) and nine (G1) thiol groups at the periph...

Wettabilities of Organosiloxane Thin Films Derived from SiCl3-Terminated Carbosilane Dendrons on Mica

Autor: Aurelie Mayeux, Chi Ming Yam, Chengzhi Cai, and Alexandra Milenkovic

Publikováno v: Langmuir. 18:10274-10278

We prepared submonolayers, monolayers, and multilayers of organosiloxanes derived from the second to fourth generation (G2−G4) SiCl3-terminated carbosilane dendrons on mica by spin-casting. The surface properties of these films, such as wettabiliti
