CO2-Selective Nanoporous Metal-Organic Framework Microcantilevers.

Nanoporous anodic aluminum oxide (AAO) microcantilevers are fabricated and MIL-53 (Al) metal-organic framework (MOF) layers are directly synthesized on each cantilever surface by using the aluminum oxide as the metal ion source. Exposure of the MIL53-AAO cantilevers to various concentrations of CO2, N2, CO, and Ar induces changes in their deflections and resonance frequencies. The results of the resonance frequency measurements for the different adsorbed gas molecules are almost identical when the frequency changes are normalized by the molecular weights of the gases.

Adsorption and desorption characteristics of alcohol vapors on a nanoporous ZIF-8 film investigated using silicon microcantilevers.

Zinc oxide nanorods were synthesized directly on a silicon microcantilever and converted into a nanoporous ZIF-8 film via a solvothermal reaction. The simultaneous measurements of the resonance frequency and deflection of the cantilever revealed that the adsorption of alcohol vapors induced a structural change in the ZIF-8 framework.

Synthesis and cellular uptake properties of guanidine-containing molecular transporters built on the sucrose scaffold.

Novel sucrose-based G7 molecular transporters show different patterns of intracellular localization depending on the nature of the linker chains as well as the fluorescent dyes.
