Hey there,

Take a look into the Unity Script Reference. There are 6 functions for collision detection.

OnTriggerEnter

OnTriggerStay

OnTriggerExit

OnCollisionEnter

OnCollisionStay

OnCollisionExit

They're used like this:
void OnTriggerEnter(Collider other){ //the collider other collides with assigned object  
do this
}

Be aware you need to attach colliders,triggers and rigidbodys for your collisions to occur

Here’s a link to the reference: http://unity3d.com/support/documentation/ScriptReference/30_search.html?q=collision

also you can check the manual about Rigidbodies. There’s some useful information in there
