When something is shaped like a string of beads, such as a beaded chain or an arrangelement of particles, the word moniliform is the perfect word to describe it. See, for example U.S. Patent No. 7,291,392.
In fact when the string of beads configuraion forms long fibers or strands, you might have a moniliform fibriliform configuration, as was described in U.S. Patent No. 6,541,627.
