1. A method of forming one or more concentrated volumes of microbeads, the method comprising the steps of:

  • (a) flowing a focused stream of a polymer solution and/or suspension towards a fluid bath, with the polymer solution and/or suspension comprising a polymer dissolved and/or dispersed in a medium;

    (b) flowing a focusing stream of a focusing fluid towards the fluid bath, and into intersection with the focused stream;

    (c) flowing the focusing stream and the focused stream from intersection with one another, so as to form the microbeads in the fluid bath; and

    (d) flowing a volume of the focusing fluid from the fluid bath, so as to concentrate the microbeads in the fluid bath,
