[Bacteriological spectrum and drug susceptibility of pus from severe intra-abdominal infected patients with abdominal trauma].

Objective: To retrospectively analyze the bacteriological spectrum and drug susceptibility of pus flora from abdominal traumatic patients with severe intra-abdominal infection.

Methods: A total of 41 severe intra-abdominal infected patients with abdominal trauma were recruited to collect 123 abdominal pus specimens. And the results of laboratory microbiology and drug sensitivity were analyzed with the WHONET 5.

Co-assembled thin films of Ag nanowires and functional nanoparticles at the liquid-liquid interface by shaking.

In this paper, we report the fabrication of co-assembled thin films composed of silver nanowires (NWs) and Au nanoparticles (NPs) at the liquid-liquid interface (water-chloroform) by vigorous shaking. The composition of co-assembled thin films can be controlled by adjusting the concentration of the nanosized building blocks. As a versatile interfacial assembly method, other nanoparticles such as Ag2S and Fe3O4 NPs can also be co-assembled with Ag NWs using the same procedure.

A general strategy for self-assembly of nanosized building blocks on liquid/liquid interfaces.

A family of water/oil interfaces is introduced to provide effective platforms for rapid fabrication of large-area self-assembled nanofilms composed of various nanosized building blocks, including nanoparticles (NPs), nanocubes (NC), nanowires (NWs), and nanosheets, at room temperature. As a general interfacial assembly method, NWs and NPs are co-assembled at the liquid/liquid interface. The as-prepared co-assembled Ag NW and Ag NC films show high surface-enhanced Raman spectroscopy (SERS) intensity, the SERS performance being strongly dependent on the number ratio of the two kinds of nanosized building blocks.
