Viscoelastic and swelling properties of glucose oxidase loaded polyacrylamide hydrogels and the evaluation of their properties as glucose sensors

New hydrogels based on the interpenetration of physical gels of agarose and chemical gels of polyacrylamide

“…Gel volume transitions can be induced by temperature, pH, or ionic strength, among other stimuli. The phenomenon has prompted researchers to investigate gels as potential actuators, artificial muscles, sensors, controllable separation membranes, and vehicles for drug delivery [6][7][8][9][10][11]. Gels are particularly appropriate for biomedical applications because of their ability to simulate biological tissues [12].…”

Electric field assisted transdermal drug delivery from salicylic acid-loaded polyacrylamide hydrogels

“…Characterizations PAAM was chemically polymerized through the free radicalization and subsequently cross-linked at 27°C (Fernandez et al, 2005). The molecular weight between cross-links, the mesh size, and the cross-linking density are parameters (equations 3-5) used for characterizing the porous structure of the hydrogel for the drug delivery system.…”

Preparation and Characterization of Hydrophobic-Associated Microspheres for Deep Profile Control in Offshore Oilfields

“…On one hand, an appropriate addition of DEA could enhance the hydrophobic association action and physical crosslinking and reduce the chain length between network junctions L c [42]. On the other hand, the hydrogen bond formed between ether bond and amide group in chains and water strengthens the ability of enveloping water, thus improving the system viscosity [43][44][45]. However, the viscoelasticity decreases rapidly with further addition of DEA beyond 0.22%.…”
