Creation of nanostructures utilisins near-critical fluids: The gas-liquid coexistence curves terminate at the critical point. As fluids approach their critical points, large molecular clusters are formed and as a result, the physical properties such as the specific heat and compressibility diverge. A variety of nanostructures are formed via self-assembly near the critical points. I show carbon onions,...
The surface modified (carboxylation or oxidation) nanodiamonds provide the chemical or physical conjugation with the bio-molecules to form the bio-functionalized nanodiamonds. The protein lysozyme absorbed on nanodiamonds can interact with E. coli bacterial cells. The lysozyme-nanodiamonds complexes were demonstrated to retain their antibacterial activity which allows constructing the indicator system...
The paper presents micromechanical cantilever sensors with self-sensing element integrated for trace-level bio/medical detection. To significantly improve sensing performance, nano-size related effects are found and utilized that mainly come from surfaces/interfaces. Such effects can be categorized into three kinds, which sequentially are the surface effects due to the cantilever dimension shrunk...
A low-cost, flexible, and disposable immunosensor is presented in this paper. The single-walled carbon nanotubes (SWNT) and biomolecules are self-assembled on micro patterned electrodes. The immuno-chip acts as the platform of a horseradish peroxidase (HRP) labeled sandwiched Enzyme-Linked Immunosorbent Assay (ELISA). The pH change induced by the biochemical reactions influences the electrical conductance...
