⚠️ Common Misconceptions
Misconception 1: "Nanoparticles are just very small particles with the same properties as the bulk material"
This is incorrect and is the central misconception about nanotechnology. Nanoparticles can have significantly different properties from the same material in bulk form. Gold is normally chemically inert and gold-coloured — gold nanoparticles can be highly reactive catalysts and appear red or purple. The difference arises from the dramatically increased surface area to volume ratio and quantum mechanical effects at this scale.
Misconception 2: "Nanoparticles are completely safe because the material is the same"
The changed properties of nanoparticles mean their behaviour in the body and environment is also potentially different. Nanoparticles may be able to penetrate cell membranes or cross the blood-brain barrier in ways that bulk materials cannot. The health and environmental impacts of nanoparticles are not yet fully understood, which is why scientists take a precautionary approach.
Misconception 3: "Fullerenes are the same as nanoparticles"
Fullerenes are one specific type of carbon nanoparticle, but nanoparticles covers a much broader category of particles from any material that are in the 1-100 nm range. Nanoparticles can be made of silver, titanium dioxide, iron oxide, gold, and many other substances — not just carbon. Fullerenes are the carbon-specific cage structures.
