The Versatile Metallic Nanoparticles: Transforming the Future of Biomedicine and Engineering
Nanoparticles have always fascinated the Nano scientists with their huge potential in the fields of biomedicine and engineering. Fe3O4, silver and gold nanoparticles are not only good catalysts but they are also being used in different biomedical and engineering fields with successful deployments.
These metallic nanoparticles can easily be obtained from online stores. Nanotechnology deals with the particles that belong to the dimensional group of 100th of manometer or less.
These nanoparticles can easily be synthesized and modified with various chemical functional groups to form different elements. Their numerous points of contacts allow them to be used with antibodies, ligands, and necessary drugs for biomedical purposes.
Magnetic separation, pre concentration of target analyses, targeted drug delivery, vehicles for gene and drug delivery and diagnostic imaging systems like MRI, CT, PET, ultrasound, SERS, and optical imaging have evolved with the use of metallic nanoparticles.
The Different Metallic Nanoparticles and Their Roles in Modern Life
Fe3O4 Nanoparticles and Its Uses: Superparamagnetic iron oxide nanoparticles (SPION) are largely used in the biomedical field for their magnetic properties. The main usage of them occurs in magnetic separation technologies for early detection of inflammatory, cancer, diabetes, and atherosclerosis. Along with this they are also used as resolution contrast agents for MRI. For targeted drug delivery and imaging, hyperthermia, gene therapy, stem cell tracking, molecular tracking these has been highly useful.
Uses of Gold Nanoparticles: Since the Roman ages gold nanoparticles, commonly known as the colloidal gold solution, due to its different hues, red, pink, purple and others, have been used for staining glasses to decorate them. In the Modern age they are mostly used for gold nanowire sensors to detect proteins, pollutants and other label free molecules in a food to determine its consumption ability.
Other uses include
1. As a connector among the resistors, conductors and other elements inside a chip.
2. As an element in the photodynamic therapy to kill the tumour cells under high temperature.
3. In biological imaging.
4. As a carrier of therapeutic elements to the affected cells in human bodies.
5. As probes in electron microscopy.
6. To diagnose the cancer affected cells and other major infections.
Silver and Silver Oxide Metallic Nano Sized Particles& Applications
Among the most used metallic nanoparticles Silver and Silver Oxide nanoparticles have unique electrical, optical, antibacterial and thermal qualities which enables them to be used in a wide range both medically and industrially.
For quantitative detection these metallic Nano sized particles are largely used in biosensors and numerous assays.
In food, apparel, cosmetics and many other regular usable materials these nanoparticles are used for their antibacterial properties.
To enhance thermal and electrical capability these nanoparticles are used in conductors.
For metal enhanced fluorescence and surface-enhanced Raman scattering these nanoparticles are used to successfully harvest light.
Silver Nanowires are used as conductive coating for transparent conductors.
In enhancing plasmonic sensitivity in antennas the nanoparticlesattached in silver nanowires are hugely responsible.
In nanocomposites they help in showing the dielectric features of the composites.
As it has already been mentioned the above discussion shows how metallic nanoparticles have changed the modern world and transformed it in several ways. And there are several online resources where theseagents can easily be ordered in required shape, size and colours for any biomedical and industrial purposes.
