Nanotechnology can even be used in the future to treat lifethreatening diseases like cancer. However it does have some drawbacks for example toxicity environmental harm and organ damage caused by nanoparticles.

How do you get nanoparticles out of your body?

Even insoluble nanoparticles which reach the finely branched alveoli in the lungs can be removed by macrophage cells engulfing them and carrying them out to the mucus but only 20 to 30 per cent of them are cleared in this way. Nanoparticles in the blood can also be filtered out by the kidneys and excreted in urine.

How can you reduce the toxicity of silver nanoparticles?

To solve the problems associated with this polymer coatings are used which are an effective way to reduce the apparent toxicity of nanoparticles. Petrow et al. obtained core-shell nanoparticles obtained by coating Ag NPs with a cross-linked poly (L-lysine) coating containing doxorubicin.

What is Nano poisoning?
