Designed by boffins, possibly in white coats (2-3)
I believe the answer is:
hi-tec
'designed by boffins' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'in white coats' is the wordplay.
'in' says the answer is hidden in the clue.
'HI-TEC' can be found hidden inside 'white coats'.
'possibly' acts as a link.
Can you help me to learn more?
(Other definitions for hi-tec that I've seen before include "Unwanted post (colloq,)" , "(Of equipment) advanced (variant spelling)" .)
