What is the name of the device or process developed by a professor at
harvard that monitors cell's reactions to protein.  It is micro something.

The word microarray comes to mind, although it's difficult to tie out
the other details you are looking for.  For a discussion of the
evolving technology and competition for patents, see here in a Wired
article from June 2000:

Many variations on this theme exist now, and it is possible to speak
of both protein and nucleotide microarrays, as well as fabrication
involving carbon nanotubules as well as "traditional" glass
substrates.
