In this work, salicylic acid (SA), a non-steroidal anti-inflammatory, was chemically
incorporated into hydrogel systems to achieve sustained SA release profiles. With its anti …

Orally administrable hydrogel was prepared by crosslinking chitosan (CS) with γ‐poly
(glutamic acid)(γ‐PGA) for an excellent pH‐responsive colon‐targeted drug delivery system …

This paper addresses development of novel pH-sensitive interpenetrating polymeric network
(IPN) microgels (MGs) based on chitosan, acrylamide-grafted-poly (vinyl alcohol) and …

Sažetak The purpose of this study is to develop novel intestinal-specific drug delivery
systems with pH sensitive swelling and drug release properties. Methacrylic-type polymeric …

A novel pH-sensitive hydrogel system composed of a water-soluble chitosan derivative (N, O-
carboxymethyl chitosan, NOCC) and alginate blended with genipin was developed for …

A novel pH-sensitive hydrogel based on dual crosslinked alginate/N-α-glutaric acid chitosan
(GAC) was prepared. The homogeneous alginate/GAC solution was dropped into calcium …

A drug-loaded gel (CSPP) based on ionic crosslinked chitosan (CS) and polyelectrolyte
complexes of poly (acrylic acid)(PAA) with poly (vinylpyrrolidone)(PVP) was prepared by …

Novel biodegradable and pH-sensitive hydrogels composed of four types of pH-sensitive
polyacrylic acid derivatives (PAAD) and a biodegradable poly (l-glutamic acid)(PGA) …

Injectable hydrogels with notable mechanical properties and self-healing ability are
promising carriers for use as a drug delivery system. Here, adipic acid dihydrazide (ADH) …

In the current research work, pH-sensitive hydrogels were prepared via a free radical
polymerization technique for the targeted delivery of 5-aminosalicylic acid to the colon …
