Perhaps you should try some spelling variations:
sequencing microarrays » sequencing micrornas, screening microarrays, sensing microarrays
sequential microarray » sequences microarray
surface function » surfaces friction, space function, surface reactions
function program » functional program, functions programs, functional programs

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: surface function program ((sequential microarray) OR (sequencing microarrays)) chips~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "surface function program ((sequential microarray) OR (sequencing microarrays)) chips".
• Adding a wildcard symbol may retrieve word variants: surface function program ((sequential microarray) OR (sequencing microarrays)) chips*.
