Isolation of power supply from circuit?

Hello,

          I wish to isolate my power supply from my circuit which detects emg signals, which are very low amplitude(1-2mv) and noise sensitive. How should i achieve this so as to induce minimum power supply noise in the signal? Should i use DC to DC isolated converters? If so which one do i use and how do i select ?
