How does chemotaxis work?

I've always been interested in finding out about just how antibodies can 'find' their target antigens- enlighten me please!

You're asking two different questions. Antibodies don't interact with antigens by chemotaxis. Chemotaxis is when an organism moves in response to a chemical stimulus in the environment (like how you might move away from an area if you smelled a skunk, or if you moved towards an area if you smelled fresh baked cookies). 

Are you asking about antibodies or chemotaxis?
