Nanoporous anodic aluminum oxide (AAO) microcantilevers are fabricated and MIL-53 (Al) metal-organic framework (MOF) layers are directly synthesized on each cantilever surface by using the aluminum oxide as the metal ion source. Exposure of the MIL53-AAO cantilevers to various concentrations of CO2, N2, CO, and Ar induces changes in their deflections and resonance frequencies. The results of th...

Recently, there has been a growing interest in point of care devices capable of detecting nucleic acids in clinical and environmental samples. Nucleic acid detection requires, however, various sample preparation steps that complicate device operation. An attractive remedy is to integrate many, if not all, sample preparation operations and nucleic acid amplification into a single reaction chambe...

Mechanically robust implants are being used in many different parts of the body for various applications in orthopedics, cardiovascular stents, and defibrillators. However, there are numerous problems to overcome, such as reducing infections, enhancing implant bonding, and preventing restenosis in cardiovascular stents, among others. A central strategy is to incorporate therapeutic agents that ...

Nanoporous Pt-Co alloy nanowires were synthesized by electrodeposition of Co-rich Pt(1)Co(99) alloy into anodic aluminum oxide (AAO) membranes, followed by a dealloying treatment in a mild acidic medium. These nanowires consist of porous skeletons with tiny pores of 1-5 nm and crystalline ligaments of 2-8 nm. Morphological and compositional evolutions of the porous Pt-Co nanowires upon dealloyi...

PURPOSE Although the laser has become one of the most commonly used tools for implant dentistry, research is lacking on whether or not the laser causes any changes on the surface of titanium (Ti) implants. The present study analyzed the morphology, composition, crystal structure, and surface roughness changes of machined and anodized Ti surfaces, irradiated with erbium chromium-doped yttrium-sc...
