Superhydrophobic surfaces by creating surface roughness followed by coating with low-surface-energyfluorinated materials have been intensively developed on cotton fabrics. However, exploring superhydrophobic surfaces withnon-fluorine components and further improving their attachment with cotton fabrics is still challenging. Herein, wedeveloped a superhydrophobic surface on cotton fabric by dip coating with hexadecylamine (HDA) modified coppernanowires (Cu NWs) based on the coordination between Cu atoms and amine groups. The HDA modified Cu NWs not onlycreated surface roughness, but also decreased the surface energy, leading to a superhydrophobic cotton fabric with watercontact angle of 164 °±2.0 °. Furthermore, ultrasonic washing and tape peeling tests exhibited the Cu NWs were adheredtightly to the surface of cotton fibers, owing to the strong hydrogen bond between amine groups on HDA molecules andhydroxyl groups on cotton fibers. In addition, the superhydrophobic cotton fabric showed excellent antifouling, oil-waterseparation and infrared reflection properties. It is believed that this facile method provide promising industrial applicationsfor fabricating superhydrophobic surfaces on other substrates.

The rising cases of multidrug-resistant Acinetobacter baumannii (Ab) and the lack of effective drugs call for quick attention. Here, based on a Tn7 transposon and Xer/dif system, we constructed a stable, selectable marker-free autoluminescent Ab capable of producing visible light without extra substrates. Utilization of this autoluminescent reporter strain has the potential to reduce the time, effort and costs required for the evaluation of activities of anti-Ab drug candidates in vitro.
