Diffusion of Cesium Ions Labeled with 134 Cs in Agar Gel Containing Alkali Metal Iodides: Obstruction Effect and Activation Energy

Diffusion-Based and Long-Range Concentration Gradients of Multiple Chemicals for Bacterial Chemotaxis Assays

“…The H-shaped channel filled with agarose gel showed similar diffusivity as the main channel filled with a buffer solution since the agarose gel is composed of 99% water. Although it has been reported that diffusivity slightly decreases in high hydrogel concentrations (<∼10%), we neglected the difference in simulations. After 6 h, the fluorescent signals reach the center of the channel across the H-shaped structure and along the long microchannel, implying that long-range concentration gradients are well generated.…”

“…Tracer diffusion of various uni- [1][2][3] and bivalent [4][5][6] ions in different supporting electrolytes under different experimental conditions has been reported by this laboratory. In our previous paper, we reported a study of the activation energy and obstruction effect for tracer diffusion of Cr 3+ ions in agar gel media containing different electrolytes.…”
