If it works at ph 5 - 5.5 the reaction is likely happening inside
endosomes inside of the cell where the ph is supposed to be in that range.
Also, with some nanoparticles much of the material ends up trapped in protective sacs called
endosomes inside the cell, and there can be potential toxic side effects.

In their latest research, Lawrence Rajendran, of the University of Zurich in Switzerland, and his colleagues discovered that, unlike non-amyloid proteins, the Alzheimer's - associated amyloid precursor protein is cleaved by β - secretase in membrane - bound compartments
inside cells, called
endosomes.
Using lab - grown mouse astrocytes with variant forms of NHE9, the researchers found a change in the pH (acidity)
inside cellular compartments called
endosomes, which in turn altered the ability of cells to take up glutamate.
In a paper published in November, working with MIT graduate student Jungmin Lee and chemistry professor Moungi Bawendi, the researchers showed that they could get quantum dots
inside human cells grown in the lab, without the particles becoming confined in
endosomes or clumping together.
After finally receiving Mirkin's thin - optical microscopy data by air mail, Lévy and Mason re-analyzed it and determined the absence of any evidence for endosomal escape, while all Sticky - Flare particles appeared to be localized exclusively
inside vesicular membrane compartments, i.e.,
endosomes (Mason & Levy, bioRxiv 2015).
