pH-sensitive chitosan-polyvinyl pyrrolidone hydrogels as controlled release system for metronidazole delivery;

Study on pH sensitivity 0f PVP/CHI blend hydrogels;

The research about pH sensitivity of AAm/Ac hydrogel;

The results show that the hydrogels have amphiphilicity and different pH sensitivity compared with chitosan.

Synthesis and characterization of a novel pH-sensitive coating materials;

Preparation and properties of novel pH-sensitive chitosan/gelatin hydrogels

The structure and properties of temperature-sensitive hydrogels,pH-sensitive hydrogels and pH/temperature-sensitive hydrogels and their applications in drug delivery systems were reviewed.

Advances of pH-sensitive in situ gels research;

Study of a Novel Fast-swelling and pH-sensitive Gelatin Hydrogel;

A Study on the Preparation and Behavior of Temperature and pH-sensitive Hydrogels;

A thermo and pH sensitive interpenetrating network hydrogels beads were prepared with both calcium alginate and PNIPAAm hydrogels which were synthesized by free radical aqueous solution polymerization using APS(ammonium persulphate)/Na 2S 2O 5(Sodium pyrosulfite) as redox initiators in a simultaneous interpenetrating network process.

An interpenetrating network like hydrogel of PE-g-AAm/AAc with sharp pH sensitive was obtained.

The environmental sensitive properties of temperature-sensitive and pH-sensitive hydrogels are reviewed and the mechanisms of such hydrogels are discussed.

pH-sensitive vesicles are designed to undergo acid-triggered destabilization,pH-sensitive vesicles were prepared from alpha-tocopherol hemisuccinate (THS) in Tris-HCl buffer.
