One particle system detecting collision from another particle system

Unity Engine

Is it possible for one particle system (shuriken) system to detect collision from another particle system (shuriken)?

I’m trying to create a cool animation when two gases collide.

Suggestions if the above is impossible?

Thank you.

In the current version, for 2D particles are simply crap.
Let’s hope new updates: /

Yes! Fingers crossed for a future update in regards to 2D particles.

My workaround was to attach primitive 2D collider components to the parent game object particle system.

Kinda hacky, but it worked.
