Thermally sensitive reversible microgels formed by poly(N-Isopropylacrylamide) charged chains: A Hofmeister effect study

- Stable PNIPAM particles are reversible formed from single charged chains.
- Hydration/dehydration of PNIPAM is extremely sensitive to test Hofmeister effects.
- Particle diameter as well as the surface charge is controlled by ionic specificity.
- Higher hydrated ions interact strongly to favor higher dehydration of PNIPAM.
- Poorer hydrated ions accumulated on pNIPAM as this becomes more hydrophobic.
