Has someone designed a board game where players travel through an animal or plant cell?

I need to know for a school project I'm supposed to do. I was wondering, before I put forth all my effort into making this game, if someone has already done this before and has pictures, or steps, or something that can help me make this board game. Thanks!

There's a movie called Fantastic Voyage. The theme is similar. You might want to rent it or read the synopsis online.
