Fig. 1 (a) Colloidal trimers can be discriminated by the bending angle (q) defined in this panel. (b) Experimental example of an isomer with q 1⁄4 85 . (c) Raw data illustrated: mean-squared angular displacement is Colloidal particles stand at the cross-section of chemistry, biology, and engineering; they underpin technology in fields that span pharmaceuticals, foodstuffs, and chemical sensors....
