Application

In general, RbCl can be used as an electrolyte for water.

Nanowires (en:Nanowires) are electrochemical probes that are placed on mica with diluted RbCl and have good directivity.

RbCl transformed receptor cells are among the most abundant applications of this compound.The cells were treated with a low osmotic pressure solution containing RbCl.Thus, membrane proteins are removed to bind negatively charged DNA.
