objective(s): pharmaceutical industries are leading to improved medications that can target diseases more effectively and precisely. researchers have intended to reformulate drugs so that they may be more safely used in human body. the more targeted a drug is, the lower its chance of triggering drug resistance, a cautionary concern surrounding the use of broad-spectrum antibiotics. the aim of t...

We report a microfluidic approach to produce monodisperse pH-responsive microcapsules with precisely controlled release behavior. The solid microcapsule shells are composed of a biocompatible pH-responsive polymer and robustly encapsulate an active material; however, when exposed to a trigger pH, the shells degrade and ultimately release the microcapsule contents. We control the trigger pH by u...

Polymer-drug conjugates are becoming established as a shining platform for drug delivery. Incorporation of pH-responsive linker between drug and polymer is expected to realize triggered release of bioactive agents from conjugates in specific sites, either in mildly acidic extracellular matrices of tumor tissues or, after cellular internalization, in acidic endosomes and lysosomes. As an emergin...

Chronic wounds do not heal within 3 months, and during the lengthy healing process, the wound is invariably exposed to bacteria, which can colonize the wound bed and form biofilms. This alters the wound metabolism and brings about a change of pH. In this work, porous silicon photonic films were coated with the pH-responsive polymer poly(2-diethylaminoethyl acrylate). We demonstrated that the pH...

objective(s): nowadays hydrogels are one of the upcoming classes of polymer-based controlled-release drug delivery systems. temperature and ph-responsive delivery systems have drawn much attention because some diseases reveal themselves by a change in temperature and/or ph. the objective of this work is to prepare and characterize composite membrane using responsive nanoparticles into a polymer...
