Venus Express did aero-breaking to go into orbit in 2005(?). I don't think it was configured to scan its surface for microbes afterwards, maybe we could add something like that for later missions. IIRC, there's only a thin layer of atmosphere where we think the microbes live, and I'm not sure if VE (or future missions) descended to that layer during aero-breaking, but it's an idea.
