Mimicking Immune Processes by Positioning Antibodies on Surfaces — A Nanoengineering Approach

Liu G-y., Liu M., Amro N., Komanicky V., Liu G-y., Liu M., University of California Davis, US

Antibody-antigen interaction is one of the most fundamental biospecific interactions. While the antibody-antigen monovalent and divalent bindings are relatively well-known in solution phase, controlling the valency on surfaces has not been attempted. Using scanning probe [...]

System Identification for Motion of Proteins Using an AFM-based Nanorobotic Manipulation

Park J., Kim B-K., Kim D-H., Kim B-K., Kim D-H., Lee K-I., Korea Institute of Science and Technology, KR

It is greatly important to understand the mechanics of AFM-based nanorobotic manipulation for efficient and reliable handling of nanoparticles. Robust motion control of an AFM-based nanorobotic manipulation is much challenging due to uncertain mechanics in [...]

Converging Technologies (NBIC)

Bainbridge W.S., National Science Foundation, US

The convergence of nanotechnology, biotechnology, information technology and cognitive science can greatly improve human performance over the next ten to twenty years. The chief areas of application include: expanding human cognition and communication, improving human [...]

A Fokker-Planck Approach For Modeling Integrated NanoBio Systems

Jenkins J.W., Sundaram S., CFD Research Corporation, US

Physics-based, high-fidelity simulations have emerged as indispensable tools in the design of complex, microfluidic devices (lab-on-chip). However, ab-initio analysis becomes increasingly complicated as the dimensions of the device approach nanoscales and molecular information/interactions must be [...]

Biologically Inspired Controls over Assembly of Crystalline Nanostructures

De Yoreo J.J., Orme C.A., Qiu R., Dove P.M., Lawrence Livermore National Laboratory, US

By utilizing small molecules and proteins to modulate crystal nucleation and growth, living organisms produce single nanocrystals and nanocrystal composites that exhibit control over the location, phase and crystallographic orientation of the nuclei, as well [...]

DNA base damage: A Car-Parrinello Molecular Dynamics Study of Guanine and Thymine with an OH Radical

Wu Y., Mundy C.J., Colvin M.E., Car R., Lawrence Livermore National Labs, US

Understanding the basic chemistry of radicals and DNA bases is an important step in characterizing the potential damage to DNA. The chemical level understanding of such damage has far reaching implications for radiation therapy, health [...]

Electrohydrodynamic Interactions of an AFM Tip and a Biological Membrane

Fan T.H., Fedorov A.G., Georgia Institute of Technology, US

In biological applications, AFM imaging needs to be performed in the natural (aqueous) living environment of the cell in order to observe molecular level interactions and biochemical processes in-situ in the electrolyte solution and to [...]

Nanoscale Activated Field on Cermic Electret In Pseudobiological Environment

Nakamura S., Ueshima M., Kobayashi T., Yamashita K., Tokyo Medical and Dental University, JP

A pseudo-biological environment using simulated body fluid (SBF) has been widely accepted as an osteobonding estimation of biomaterial surfaces. In the present study, the interactions at the interface of the polarized HA surface and the [...]

High Resolution Compton Imaging of Nanostructures

Wang J., Kim K., UMass Dartmouth, US

We describe a novel and unique imaging technique based on Compton scattering, a fundamentally different physical process than those based on photo-absorption techniques (such as XPS and its variants UPS/SRPS). This is unique since it [...]

Growth of InAs Quantum Dots Using the Strained Superlattices and Their Optical Properties

Leem J-Y, Choi H-K, Jeon M.H., Lee J.W., Leem J-Y, Cho G.S., Choi H-K, Department of Optical Engineering, KR

we have studied the growth of self-assembled quantum dots (QDs) using Stranski-Krastanow growth mode and strain-reducing layers for long-wavelength applications with narrow linewidth in photoluminescence (PL) emission. InAs QDs were grown on the strained superlattices, [...]
