Is there any way to make a Google search case-sensitive?
Someone else has designed a website to do just that
To solve this problem and help you conduct case sensitive searches on Google, someone has created a Google Appengine powered search engine at Case Sensitive Search – it scans through Google search results and filters out results that match the case of your search query.
No, from "Google search basics: Basic search help":
Search is always case insensitive. A search for [ new york times ] is the same as a search for [ New York Times ].
