Our colleagues here at the UCB Space Sciences Lab recently reported the first capture and analysis of interstellar dust particles. They were aided by thousands of volunteers in the Stardust@home project.

What if any is the difference between solar system dust particles and those labled "interstellar"... I suspect the origins of dust in general in space is somewhat difficult to determine. While dust near a planetary body might be associated with said planet in actuality the gravitational wells of planets act as a vacuum as the solar system travels through interstellar space so dust is likely to be of indeterminate origin.

Given the numerous collisions in planetary space, asteroids, comets, meteors, etc. Dust is far more prevalent near a star. Unless we can have Voyager's and Pioneers in a few decades do collections I maintain that dust within 1/2 light year of the sun is most likely of Sol system origination with random strays form elswhere's exceedingly rare and likely exhibiting no unique properties to allow differentiation.
