Perhaps you should try some spelling variations:
analytical functionality » analytic functionals, optical functionality, chemical functionality
spatial functionality » spatial functional, optical functionality, potential functionality
programme function » programming function, programme action, programs functional
microarray chips » microarray chip, microarrays chip, microarray cross

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "programme function ((spatial functionality) OR (analytical functionality)) microarray chips~".
• Adding a wildcard symbol may retrieve word variants: programme function ((spatial functionality) OR (analytical functionality)) microarray chips*.
