message: This is one phrase (below) that does not clearly state what the properties of nanoparticles are.  Since I don't know how to edit it I Will leave it will this message, but I think something could be done to clarify.
  
"The interesting and sometimes unexpected properties of nanoparticles are not partly due to the aspects of the surface of the material dominating the properties in lieu of the bulk properties."

message: There seems to be a lot of speculation in this under the section on safety.  References should be provided for this section. Some of this information is stated as if it were fact, but the information is often not factual or unkown.  Very little research has been done in this area to date.  198.124.230.2 20:30, 15 March 2007 (UTC)

message: In the section on safety the following claim appears 
'Diesel nanoparticles have been found to damage the cardiovascular system in a mouse model.', 
yet upon reviewing the linked reference, the word 'diesel'(or any specific alternate) is not used even once.
Perhaps someone thought it reasonable to assume that all nano-particulate pollution on LA freeways is strictly the result of diesel fueled vehicles.  I don't think that is the case, but even if it were, the substance probably shouldn't be called 'diesel nanoparticles'.  Nanoparticles are generally solids.  'Diesel' at STP describes a liquid.  
If the article had been more specific about diesel fueled vehicles being mostly, or even partially responsible for the nano-particle pollution, then it might be reasonable to describe it as something like 'nano-particle pollution resulting from diesel combustions', but the article did not say anything like that.
Please change the text to read something that is actually supported by the linked reference, find a more supportive reference to link, or simply drop the unsupported claim.

message: User:Akhil9gupta/NANOPARTICLE AND ITS APPLICATION: - THE REVIEW was created in 2009 about nanoparticles and while it's largely not useful, it has some sources and text that could be useful here. Could someone take a look or else take it to MFD and put it away after all these years? -- Ricky81682 (talk) 09:58, 20 March 2016 (UTC)

message: There are occurrences of nanoparticles in nature. They can be found in magmas, in rocks (for example "invisible gold"), on tectonic faults, etc.
Will adding a short section about that be appropriate?  — Preceding unsigned comment added by 87.69.94.236 (talk) 09:25, 16 March 2018 (UTC)

message: The article says, "A colloid is a mixture which has solid particles dispersed in a liquid medium."
This simply is not true. A mixture which has solid particles dispersed in a liquid medium is an example of a colloid (if the size etc criteria are met). A colloid is simply one or more discontinuous phases of matter dispersed in a continuous phase of matter and that meets rather arbitrary size critera. Neither particles or liquids are a requirement. The incorrect definition in the article highlights the utter confusion that has arisen since "nano" has become the cash cow for R&D and the underpinning colloid science for nanodispersions etc has been usurped, misunderstood, reinvented and generally forgotten.

message: The History section included the passage
:As Muslims were not allowed to use gold in artistic representations, they sought a way to create a similar effect without using real gold. The solution they found was using luster.
I cannot access the reference, but even if it contains the claim "Muslims were not allowed to use gold in artistic representations", I wonder whether that claim is true. --Jorge Stolfi (talk) 09:26, 29 February 2020 (UTC)
