Nanomaterials can be used to develop pharmaceutical products targeted at specific organs and cells in the body, for example, cancer cells.
FREMONT, CA: Carbon-based nanomaterials are primarily composed of carbon and can take the shape of ellipsoids, hollow spheres, or tubes. Nanosilver, nanogold, quantum dots, and nano oxides such as titanium dioxide are all examples of metal-based nanomaterials. Dendrimers are branched polymers that are nanoscale in size. Additionally, composites combine nanoparticles with other nanoparticles or with more extensive, bulkier materials.
Below are some of the types of nanomaterials.
A nanoparticle is a three-dimensional object that exists on the nanoscale, between 1 and 100 nm. Nanoparticles are critical in the biomedical and pharmaceutical industries but also energy storage technologies. Gold nanoparticles, for example, are attracting considerable attention due to their broad potential for biomedical applications, particularly cancer treatment. Liposomes and micelles are both excellent vehicles for drug delivery. Ferric nanoparticles stabilized in iron-oligosaccharide complexes are frequently used in intravenous iron therapy. RNA nanoparticles are used in vaccines, gene silencing, and sunscreens as the TiO2 pigment. Additionally, researchers are examining polyionic nanoparticles for their potential use as electrode material in rechargeable batteries.
Graphene was one of the first two-dimensional materials to spark interest in these materials. Numerous studies on energy conversion and storage have examined the magnetic properties of two-dimensional nanomaterials. However, there is more: Metal layers, for example, contribute significantly to the visual performance of the display assembly. Due to their suitable mechanical and chemical properties, nanocrystalline TiO2 coatings are one of the most frequently used materials for hard tissue replacement. SAMs have spontaneously formed assemblies of organic molecules adsorbed on solid surfaces that are commonly used as biosensors.
Quantum dots are nanoscale artificial semiconducting crystals capable of transporting electrons. When they are exposed to UV light, they can emit light in a variety of colors. Microwave-assisted colloidal synthesis is one method for producing these materials. Solar cells, biological applications, LED displays, photodetectors, and photocatalysts are examples of their applications.
Nanowires, nanofibers, and nanorods
Nanorods are solid nanofibers that are significant for their superior energy storage performance. While nanowires are used in various applications, including field-effect transistors, sensors, and lasers, the most effective applications of nanofibers include tissue engineering, drug delivery, cancer diagnosis, optical sensors, air filtration, and textiles. These nanoscale materials have two dimensions and are synthesized.
Nanotubes of carbon
Carbon nanotubes (CNTs) are carbon allotropes with a cylinder-shaped nanostructure. They are composed of one (single-walled CNTs) or several (multi-walled CNTs) carbon layers wrapped in a graphitic structure around a hollow core. Both the core and the wall have dimensions in the nanometer range, but the overall length of the tubes is typically much longer. Composites of carbon nanotubes dispersed in matrix materials (e.g., polymers) exhibit highly novel properties. As a result, they can be helpful in a wide variety of fields, including materials science, electronics, and optics.
