Nanoparticles

Nanoparticles are nano-objects with all three external dimensions in the nanoscale, i.e., between 1 and 100 nanometers. They are vital scientific tools which are being explored in various biotechnological, pharmacological and pure technological uses. Some notable properties of materials in the nano-scale include large surface area, special optical properties, conductance, surface plasmon resonance and the ability to form suspensions. Nanoparticles have a wide range of applications spanning across different fields like healthcare, electronics, chemistry, energy and transportation. Nanotechnology in medicine focuses on developing precise solutions for disease prevention, diagnosis, and treatment. Nanoparticles are being used in lab-on-a-chip technology for easy and efficient diagnostics. Dendrimers and nanoporous materials can be used as targeted drug delivery carriers. Tissue engineering is basically artificially activated mobile growth by using appropriate nanomaterial-based scaffolds and growth aspects. Scientists are looking into ways to develop clean, affordable, and renewable energy sources, with the help of nanoparticles. Nanoparticles are also used in filtration, catalysis, quantum computers, agriculture, and cosmetics and as building materials in sensors and semiconductor devices. Nanopowders are solid powders of nanoparticles, often containing micron-sized nanoparticle agglomerates. Nanopowders of different materials like aluminium, carbon, iron, molybdenum, silver and zinc oxide, are available on Biomall portal.
