  • "Shrinking" is the subject. – Hot Licks Jul 20 at 3:17
  • Why don't you think of eerything before the verb has there the subject, specifically the -ing clause? That's why the verb is singular. – tchrist Jul 20 at 3:19

[But shrinking the band gaps of such materials just that little bit further, to the point where a brilliant red is reflected instead], has so far proved beyond their chemical skills.

The subject of “has” is the entire sequence “but shrinking the band gaps of such materials just that little bit further, to the point where a brilliant red is reflected instead”.

The PP within the commas is not a supplement, but is sufficiently integrated into the main clause to be analysed as a modifying adjunct of extent.

This is the essential sentence:

Shrinking [something] has so far proved beyond their chemical skills.

Shrinking is the main subject, but if you want the complete subject, it would be:

shrinking the band gaps of such materials just that little bit further

The text inside the parenthetical pair of commas is just that—parenthetical; it doesn't affect the rest of the sentence.
