Perhaps you should try some spelling variations:
spatial functionality » spatial functional, analytical functionality, potential functionality
optical functionality » chemical functionality, office functionality, optimal functional
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 (optical functionality)) microarray chips~".
• Adding a wildcard symbol may retrieve word variants: programme function ((spatial functionality) OR (optical functionality)) microarray chips*.
