In this context “pH” is an important parameter to control the charge within spatial confinement and thus to control pore accessibility. Thereby, spatial confinement influences “pH” in pores. Here, we are interested in understanding the effect of spatial confinement on pore charge and “pH” in confined space by using pH-sensing dyes, fluorescence spectroscopy and in collaboration single molecule fluorescence.
