The antimycotic agent amphotericin B (AmB) functions by forming complexes with sterols to form ion channels that cause membrane leakage. When AmB and cholesterol mixed at 2:1 ratio were incorporated into phospholipid bilayer membranes formed on the tip of patch pipettes, ion channel current fluctuations with characteristic open and closed states were observed. These channels were also functiona...

The crush behaviors of steel tubes filled with nanoporous-materials-functionalized liquids are experimentally investigated under quasi-static and dynamic conditions. Results show that the nanoporous-materials-functionalized liquid can enhance the load-carrying and the energy absorption capacities of thin-walled tubes, as the buckling mode is affected. The effective buckling stress increases wit...

graphene-based nanocomposites are newly emerged materials with a wide range of applications such as in supercapacitors electrode. the high conductivity and ability for passing electric current, makes graphene an appropriate new item to be used in cells. electroactive transition metal oxides, owing fast reversible redox pairs, are used to store electrical charge. furthermore, the graphene/nio na...

Recent nanomechanical tests on submicron metal columns and wires have revealed a dramatic increase in yield strength with decreasing sample size. Here, we demonstrate that nanoporous metal foams can be envisioned as a three-dimensional network of ultrahigh-strength nanowires, thus bringing together two seemingly conflicting properties: high strength and high porosity. Specifically, we character...

We introduce individual nanoporous Au nanowire (AuNW) as a tunable one-dimensional platform for plasmon-enhanced fluorescence, with an enhancement factor of ∼62, which is ∼8-fold higher than that of smooth AuNWs. Besides, nanoporous AuNWs have much lower background emission than smooth AuNWs. These results indicate that nanoporous AuNWs are an excellent optical sensing platform.
