Nanomedicine and Metallic Nanoparticles

Drug delivery is one of the most important subject of research in medical sciences. The increase of the drug efficacy and the reduction of the side effects are among the goals of the research in this field. Scientists are working on the development of metallic nanoparticles which target the infected cells without doing harm to other neighbor cells. Au (Gold) nanoparticles, Ag (Silver) nanoparticles, Fe (Iron) nanoparticles and Cu (Copper) nanoparticles are the most researched nanoparticles which show high potential in site-specific drug delivery. These nanoparticles have unique physical and chemical properties such as, plasmatic resonance, fluorescent enhancement, and catalytic activity enhancement which make them very fascinating materials in drug delivery applications.

If we take a look at some examples of the metallic nanoparticles in drug delivery applications, we can realize the future potential of these particles. For example, Au, 99.99+%, 50-100 nm nanoparticles can be chemically functionalized with roughly 120,000 distinct molecules, which is two times higher than the surface loading capabilities of liposomes. Another example can be illustrated by Fe (Iron) nanoparticle 99.55+%, 90-100 nm, and Fe3O4 (Iron Oxide) nanoparticles, 18-28nm, Purity 98.45+%, which are MRI-monitored magnetic targeted nanoparticles. These nanoparticles can be directed toward the targeted cells using their magnetic properties. Variety of examples are available for different nanoparticles and an extensive research is being done to enhance the properties of these particles and to discover more applications for them in medical field.

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs)  have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from:  https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread that i
