#TI-BASIC, 7 bytes

This is a function that takes a binary string (through Ans) as input and returns the output as an inverted (not reversed) string, as specified. For more help, you can read through list application by not( on the TI-BASIC wiki. I'm using the compiled version because it is smaller:

»*r>Õ¸r 

In hex:

BB 2A 72 3E D5 B8 72 

Explanation

»*r - Take function input as string and convert to list

> - Pipe given list to the next operators

Õ¸r - Return the inverse of the list
