Surface and Colloid Science

The applications of copper (Cu) and Cu-based nanoparticles, which are based on the earth-abundant and inexpensive copper metal, have generated a great deal of interest in recent years, especially in the field of catalysis. The possible modification of the chemical and physical properties of these nanoparticles using different synthetic strategies and conditions and/or via postsynthetic chemical treatments has been largely responsible for the rapid growth of interest in these nanomaterials and their applications in catalysis. In addition, the design and development of novel support and/or multimetallic systems (e.g., alloys, etc.) has also made significant contributions to the field. In this comprehensive review, we report different synthetic approaches to Cu and Cu-based nanoparticles (metallic copper, copper oxides, and hybrid copper nanostructures) and copper nanoparticles immobilized into or supported on various support materials (SiO2, magnetic support materials, etc.), along with their applications i...

Cu and Cu-Based Nanoparticles: Synthesis and Applications in Catalysis.

Nanotechnology is being used to enhance conventional ceramic and polymeric water treatment membrane materials through various avenues. Among the numerous concepts proposed, the most promising to date include zeolitic and catalytic nanoparticle coated ceramic membranes, hybrid inorganic–organic nanocomposite membranes, and bio-inspired membranes such as hybrid protein–polymer biomimetic membranes, aligned nanotube membranes, and isoporous block copolymer membranes. A semi-quantitative ranking system was proposed considering projected performance enhancement (over state-of-the-art analogs) and state of commercial readiness. Performance enhancement was based on water permeability, solute selectivity, and operational robustness, while commercial readiness was based on known or anticipated material costs, scalability (for large scale water treatment applications), and compatibility with existing manufacturing infrastructure. Overall, bio-inspired membranes are farthest from commercial reality, but offer the most promise for performance enhancements; however, nanocomposite membranes offering significant performance enhancements are already commercially available. Zeolitic and catalytic membranes appear reasonably far from commercial reality and offer small to moderate performance enhancements. The ranking of each membrane nanotechnology is discussed along with the key commercialization hurdles for each membrane nanotechnology.

Polycyclic silicone membranes. Synthesis, characterization and permeability evaluation

Biosensors based on surface plasmon resonance (SPR), operating with the Kretschmann conventional arrangement, have been employed for biomolecular detection of tumor markers. However, the traditional SPR configuration presents some experimental inconveniences that are overcome by using plasmonic substrates based on nanohole arrays manufactured in metallic films. This SPR configuration exhibits the extraordinary optical transmission (EOT) phenomenon, which is explored in the monitoring of binding events that occur on the metal surface. In this work, we proposed a plasmon biosensor based on nanohole arrays built on gold film operating in collinear transmission mode by using spectral investigation for signal transduction. The SPR substrate was coupled to a microfluidic system and showed good sensitivity and linearity. A concentration of 30 ng mL−1 of human epidermal receptor protein-2 (HER2) antigen (associated with breast cancer) was detected using the integrated device; this showed its great potential to be used in tumor diagnosis.
