Synthesis of Surfactant-Modified Poly (Acrylamide-co-Potassium Acrylate) Hydrogels and Itsin vitroRelease Studies

Blend Hydrogel Microspheres of Carboxymethyl Chitosan and Gelatin for the Controlled Release of 5-Fluorouracil

“…Biopolymeric devices not only protect the drug from systemic metabolism but also shield the tissue from direct exposure of the drug. Such biocompatible CR formulations maintain the constant therapeutic concentration of a drug for a long period of time at the site of action, thus improving the drug efficacy [ 1 , 2 , 3 , 4 ]. Therefore, it is important to regulate the release of a drug by developing a formulation prepared by dispersing the drug in an inert polymer matrix [ 5 , 6 ].…”

Synthesis and characterization of acrylic acid-2-hydroxyethyl methacrylate IPN hydrogels

“…Hydrogels are a special kind of so polymeric materials having three-dimensional crosslinked networks that can absorb large quantities of water or aqueous solutions without dissolving in them. 1 There are some polymers that can change their structure and eventually their properties in response to physical or chemical changes in the environment, such as pH, 2 temperature, 3,4 ionic strength, electric eld, 5 magnetic eld 6 etc. They are known as intelligent or smart polymers.…”

Development of microbial resistant Carbopol nanocomposite hydrogels via a green process

“…The antibacterial activity of the inorganic nanocomposite P(C980-AM) hydrogels, was investigated using the disc method, according the standard procedure described elsewhere. 26,27 Nutrient agar medium was prepared by mixing peptone (5.0 g), beef extract (3.0 g) and sodium chloride (NaCl) (5.0 g) in distilled water (1000 ml) and the pH was adjusted to 7.0. Finally, agar (15.0 g) was added to the solution.…”
