Hi mak17, I put your reference into my library's search tab and it came up with many articles by your authors on Thymoquinone-and some even used similar titles including the term 'promising' and 'clinical trial' but none had this specific title including nanoparticles, and none were from the Journal of Nanoscience.
Given the large number of similar articles that turned up in my library by your author/s, I checked with google just to see if there were any mistakes in title and noticed that your article came up immediately from an online science provider (with a large price tag attached). Sorry, this is not a great deal of help. However, if you need other Thymoquinone articles by Majed AbuKhader, then there is a chance I can provide one of these. However, I'm gathering you are focusing on the nanoparticles rather than the Thymoquinone?
(I'm not expecting to be a member of this library after a few more months once finished, so my thinking is I will help out other members with article access where I can)
Best, P.
