Define "directly". The definition of dark matter is that it's electromagnetically non-interacting, therefore observing it's gravitational effect is as direct as it gets.

Since we do not know what exactly it is, defining "directly" is not really something you can do.

But, for instance, electroweak interaction is being looked at, I gather?
