A transformative oral insulin delivery method is developed for postprandial glycemic regulation. Insulin-loaded liposomes with glucose-sensitive hyaluronic acid shell can respond to the elevated intestinal glucose levels following digestion of a meal, thereby facilitating enhanced intestinal absorption in an Fc receptor (FcRn)-mediated transport pathway. This glucose-triggered ※smart insulin pill§ can remarkably reduce postprandial blood sugar levels in a chemically-induced type 1 diabetic mouse model.

A systematic study of the excitation energy dependence (EED) of the spectral position, spectral bandwidth, and quantum yield (QY) of the photoluminescence (PL) of sets of ternary AgInS2/ZnS quantum dots (QDs) of different size and size distribution, chemical composition, and surface ligands is presented. Our results demonstrate the considerable potential of EED PL spectroscopy for providing insights into the electronic energy structure and band gap energies of ternary I-III-VI group QDs with their inhomogeneously broadened PL. Single particle spectroscopy confirms the inhomogeneous broadening which was subsequently explained by theoretical modeling.
