Rice University postdoctoral fellow Qingfeng Zhang works in the laser lab where he and his colleagues discovered the unusual chiral interplay between gold nanorods and bovine serum albumin proteins, the topic of a paper in Science. Their work revealed the proteins prompt gold nanorods to form right-handed chiral assemblies while producing chiral plasmonic signals to match. The phenomenon could lead to a technique that lets researchers determine the chiral purity of proteins critical to drug design. (Credit: Jeff Fitlow/Rice University)
