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,...
This paper reports a new class of biosensors based on composite nanomaterial thin film. The composite nanomaterial film is synthesized using a simple vacuum filtration method. Using composite nanomaterial film, we can not only simplify the positioning and integration fabrication process of nanoscale materials into a functional device, but also enhance the sensing surface area significantly, which...
In this work, we report an efficient method of chemical vapour deposition, without use of any metal catalysts, for the successful synthesis of vertical graphene nanoflake films (GNFs) on Si substrate. Effects of the growth condition on the surface morphology, microstructure, and chemical composition of GNFs are characterized by using scanning electron microscopy, transmission electron microscopy,...
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...
Presented application is based on the use of carbon nanotubes for biomolecular analysis using electrochemiluminescence (ECL) detection technique ([1]-[9]). ECL is the generation of light by electron transfer between species electrochemically generated. ECL research has led to the successful ultrasensitive analysis of biomolecules in solution and commercialisation of several generations of ECL analyzers,...
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...
