In this paper, anodic bonding between silicon wafer and glass (Pyrex 7740) has been achieved at low temperature. The bond strength is measured using a tensile testing machine. interfaces are examined analyzed by scanning acoustic microscopy (SAM), electron (SEM) secondary ion mass spectrometry (SIMS). effects of the parameters on quality investigated Taguchi method. temperature used ranges from 200 °C to 300 °C. Almost bubble-free have obtained. bonded area increases with increasing unbonded...
The issue of oil/water separation has recently become a global concern due to the frequency oil spills and increase in industrial waste water. Thus, membrane-based materials with unique wettability are desired separate both these from mixture. Nevertheless, fabrication energy efficient stable membranes appropriate for process remains challenging. Herein, synergistic superhydrophilic-underwater superoleophobic inorganic were inventively created by maneuverable galvanic displacement reaction...
Herein, we developed a label-free electrochemical biosensor for sensitive detection of matrix metalloproteinase-7 (MMP-7) based on DNA enzyme-decorated nanoladders as enhancer. A peptide and single-stranded S1-modified platinum nanoparticles (P1-PtNPs-S1), which served recognition nanoprobes, were first immobilized electrode. When target MMP-7 specifically recognized cleaved the peptide, PtNPs-S1 bioconjugates successfully released from The remaining S1 electrode then hybridized with ssDNA1...
