Why is nanotechnology a difficult science?
Nanotechnology is a multidisciplinary field of research and stretches over fields like materials science , mechanics, electronics, biology and medicine. The fact that it is multidisciplinary field, sometimes make it difficult to separate it from near by sciences .
Can nanotechnology cure diseases?
With the use of nanotechnology , scientists hope to prevent illness , more quickly diagnose, control disease and treat disease with fewer side effects, and create better medical aids such as more compatible prosthetics. Nanoparticles and surfaces made of nanostructures are used in many areas of healthcare research.
What tools are used in nanotechnology?
Nanotechnology Equipment AFM Raman Systems. AFM Tips, Probes, Cantilevers. Ashers & Asher Systems. Atom Probes. Atomic Absorption Spectrometers. Atomic Emission Spectrometers. Atomic Force Microscopes ( AFM ) Atomic Layer Deposition (ALD) Systems.
How are nanoparticles removed from the body?
Traditional methods to remove nanoparticles from plasma samples typically involve diluting the plasma, adding a high concentration sugar solution to the plasma and spinning it in a centrifuge, or attaching a targeting agent to the surface of the nanoparticles .
Why are nanoparticles dangerous inside the body?
Nanoparticles can get into the body through the skin, lungs and digestive system. This may help create ‘free radicals’ which can cause cell damage and damage to the DNA. There is also concern that once nanoparticles are in the bloodstream they will be able to cross the blood-brain barrier.
Is Nano Silver toxic?
Nanosilver can interact with cellular membrane and cause toxicity . In particular, nanosilver can interact with bacterial membrane and this is considered the main mechanism for the antimicrobial toxicity of nanosilver (16, 34, 36, 95–97). Khan et al studied the interaction of nanosilver with five types of bacteria.
