## Abstract **Summary:** We investigated microcapsules composed of the weak polyelectrolytes poly(allylamine hydrochloride) (PAH) and poly(methacrylic acid) (PMA) assembled on calcium carbonate cores. These capsules are stable in the pH range from 2.5 to 11.5, undergoing reversible swelling in the

## Abstract Novel biodegradable hollow nanocapsules composed of two kinds of weak polyelecrolytes, CT and γ‐PGA, were successfully prepared by the deposition of their LbL‐assembled films onto silica particles and the subsequent removal of the silica. These CT‐γ‐PGA hollow nanocapsules showed unique
