I don't think any of the above suggests any relationship, of any kind, between The Blob and the biotech concept of green (or even gray) goo.  Here is the section which I have removed:

 *Unintended as it was at the time, The Blob is a perfect example of green goo (and of alien origin). Green goo is a biotechnology variant of grey goo.

If any form of biotechnology is in the plot line (even in speculation by a scientist in the script), let's cite that. If not, let's not have this somewhat speculative note in the article. Tony Sidaway
