Abstract
We describe a preliminary investigation of the dissolution dynamics of zinc oxide nanoparticles in the presence of cyclic esters (δ-gluconolactone and propanesultone) as slow acid generators. The particles dissolution is monitored by means of turbidimetry and correlated with the evolution of pH over time. The results could be of interest for the design of chemically programmable colloidal systems.

Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in Investigating the dissolution of inorganic nanoparticles is a topic of great relevance, both theoretical and practical, with applications ranging from advanced materials to environmental science and medicine [1,2,3,4]
We began by studying the dissolution dynamics of inorganic nanoparticles in the presence of slow acid generators
We studied the dissolution of ZnO nanoparticles by measuring the evolution of pH and turbidity over time, keeping constant the concentration of ZnO (5 mM) and varying that of the slow acid generators (50, 100, or 200 mM)
