Industrial expansion has increased the discharge of contaminated wastewater. Wastewater can be treated by adsorption with petroleum-based hydrogels but materials are not biodegradable and therefore cause secondary toxic waste. In this work, hydrogel composites prepared based on non-biodegradable polyacrylamide cassava starch (CS) poly(vinyl alcohol). The effect CS content porous structure is st...

Background. Open wound treatment requires a use of bandage material to prevent the development pathogenic microflora and provide necessary conditions for tissue regeneration.
 The aim study was compare effectiveness polyacrylamide (PAA) dextran-graft-polyacrylamide (D-PAA) hydrogels loaded with silver nanoparticles (AgNPs), antibiotics, photosensitizers bacterial infection open wounds.&#x0...

We present a new scheme for sensing biomolecules by combining an enzyme hydrogel with a photonic crystal hydrogel layer that responds to ionic strength and pH changes. We demonstrate this unique combination by successfully detecting acetylcholine (ACh) and acetylcholinesterase (AChE) inhibitors. Specifically, the sandwich assembly is composed of layers of photonic crystals and a polyacrylamide ...
