Two-dimensional micro-bubble actuator arrays were developed and studied in detail to enhance the hybridization kinetics of a DNA micro-biosensor. The hybridization between a molecular beacon, a kind of oligonucleotide probe, and its complement was investigated in a millimeter-sized PDMS based reaction chamber, where various 2D micro-heater arrays were distributed on the bottom for micro-bubble ...

In this paper, size distribution of nano-bubbles was measured by the reliable and fast method of laser diffraction technique. Nano-bubbles were produced using a nano-bubble generator designed and made based on hydrodynamic cavitation phenomenon in Venturi tubes. A Central Composite Design with Response Surface Methodology was used to conduct a five factor, five level factorial experimental desi...

The fate of bubbles formed in tissues during decompression to altitude after diving or due to accidental loss of cabin pressure during flight has only been indirectly inferred from theoretical modeling and clinical observations with noninvasive bubble-measuring techniques of intravascular bubbles. In this report we visually followed the in vivo resolution of micro-air bubbles injected into adip...

To investigate factors influencing nucleation of air clathrate hydrates in polar ice sheets, we have performed high-resolution mapping of the distributions of soluble impurities, air bubbles and airhydrate crystals versus depth in the Dome Fuji Antarctic ice. Significant correlation observed between the concentrations of air inclusions and impurities in ice along with frequent occurrence of imp...

Micro-nano bubbles (MNBs) are tiny bubbles with diameters on the order of micrometers and nanometers, showing great potential in environmental remediation. However, the application is only in the beginning stages and remains to be intensively studied. In order to explore the possible use of MNBs in groundwater contaminant removal, this study focuses on the transport of MNBs in porous media and ...

ABSTRACT We have developed an on-chip micro-pipette, which has abilities of cell injection, local regent blow, enucleation, air bubble generator, piercing cells, and micro-manipulation, made by SU-8 photoresist for cloning, chimera technology, cell assays, and artificial lipid bilayer membrane making. We used the property of SU-8 which has a sufficient stiffness enough to penetrate cells as wel...
