The accurate detection and enumeration of mycobacteria in metalworking fluids (MWFs) is imperative from an environmental protection and occupational health perspective. We report here on a comparison of the labeling efficiency of nano-immunomagnetic particles (NIMP) and free antibody (FAb) to detect mycobacteria in semisynthetic MWF by using both traditional visualization analysis and cluster a...
Rheological characteristics of Al2O3, CuO and TiO2 nano particles were investigated in oil asthe base fluid at 1 and 2 wt.%. Constitutive relations for non-Newtonian fluid were discussedbased on the power-law model. Measured viscosities of each nanofluid were used to evaluatethe power-law and consistency index. Results indicated that the nanofluid viscosity decreasedby increasing the concentrat...
The acidic extracellular environment of tumors potentiates their aggressiveness and metastasis, but few methods exist to selectively modulate the extracellular pH (pHe) environment of tumors. Transient flushing of biological systems with alkaline fluids or proton pump inhibitors is impractical and nonselective. Here we report a nanoparticles-based strategy to intentionally modulate the pHe in t...
In this paper, the effect of titanium dioxide nanoparticles on the response of the freely suspended nano-fluid was investigated in an external electric field. Applying the external electric field to liquid film carrying electric current caused the layer rotation. It was due to the surface charge response of the layer to the electric field. The effect of surface charge on titanium dioxide nano-...
In this paper, a nano-liquid/liquid waveguide coupling based on evanescent tunneling effect is demonstrated. For the first time, the feature size in the fluidic beyond the diffraction limit with changes as small as 1 nm can be imaged in the microchannel. The evanescent coupling length can be tuned by the flow rates and the fluids materials flexible than semiconductor ones. This implies that sin...
