The desired functionality of a virus fiber (such as gold-binding ability) can be programmed by manipulating the M13 virus genome, report Angela Belcher, Krystyn Van Vliet, and co-workers on p. 826. The background picture is an illustration of a virus fiber that is conjugated with cadmium selenide quantum dots and emits red light when excited by UV irradiation. The genetically tunable functionality on the virus fiber offers a convenient designing process and will bring a variety of new applications to antimicrobial, catalytic, optical, medical, and electronic fibers.
