Perhaps you should try some spelling variations:
"core-shell cancer nanoparticles" » "core-shell copper nanoparticles", "core-shell silver nanoparticles", "core-shell polymer nanoparticles", "core-shell chapter nanoparticles", "core-shell concept nanoparticles", "core-cell cancers nanoparticles"
"core-cell cancer nanoparticles" » "core-cell copper nanoparticles", "core-cell silver nanoparticles", "core-cell polymer nanoparticles"

Try widening your search to All Fields.

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: "((\"core-shell cancer nanoparticles\") OR (\"core-cell cancer nanoparticles\"))".
• Removing quotes may allow a broader search: (( core-shell cancer nanoparticles ) OR ( core-cell cancer nanoparticles )).
• Adding a wildcard symbol may retrieve word variants: (("core-shell cancer nanoparticles") OR ("core-cell cancer nanoparticles"))*.
