Context. Polyacrylamide hydrogel (PAAG) has gained importance as a synthetic soft tissue filling agent. It has been commonly employed by physicians in Europe for facial contouring and soft tissue augmentation. Previously, PAAG is considered nontoxic and well tolerated with a few mild procedural complications. Case Presentation. A 26-year-old female was hospitalized for dry cough, worsening dysp...

Hydrogels with the integrated characteristics of adhesion, self-healing, deformability, and conductivity hold enormous potential for design next-generation flexible human body posture sensor energy device. Here, we proposed a double-network hybrid polyacrylamide/poly(acrylic acid)/MXene/PEDOT:PET (PPMP) hydrogel excellent flexibility, self-healing capabilities, stability. Furthermore, PPMP cond...

The immune response after implantation of a biomaterial may shorten the functional life implant, depending on degree response. In this study, we used polyacrylamide-alginate (PAAm-Alg) hydrogel, which has been previously characterized as biocompatible material and shown to enhance regeneration cartilage in vivo, along with graphite-enhanced hydrogel (PAAm-Alg-G) non-biocompatible counterpart, e...

Background/Aim: Adipose-derived mesenchymal stem cells (AD-MSCs) have gained popularity for use in treating osteoarthritis (OA) although their long-term effects remain unsatisfactory the end stages of OA. However, clinically injectable polyacrylamide hydrogels (PAHGs) joint indefinitely, which could make them ideal candidates as AD-MSC carriers. Our aim was to evaluate whether combinations PAHG...

a gel composite (based on polyacrylamide and crosslinker cr(iii) acetate) was prepared by solvent method (distillate and water formation) and nanoclay particle (kaolinite). using xrd tests, d001 was evaluated for kaolinite nanoparticles in gel composite. kaolinite modification using dimethyl-sulfoxide led to increase interlamellar spacing from 7.21 to 10.82 o a. based on the results obtained fo...

The fabrication of ordered inorganic arrays of varying length scales and with multimodal porosities is of practical importance owing to their potential application in many areas of materials chemistry, including catalysis and separations science. A common approach to the controlled synthesis of this class of materials, first exploited in the synthesis of the MCM-41 family of molecular sieves, i...

Phenylboronic acids are a class of compounds that bind glucose and other sugars. When polymerized into hydrogels, they provide a convenient nonenzymatic means for sensing glucose concentration, provided competing sugars are present at negligible concentrations. In this paper we provide a comprehensive study of swelling of hydrogels containing methacrylamidophenylboronic acid (MPBA), as a functi...

We report on a novel gel based on diffusive gradients in thin films (DGT) for the simultaneous measurement of cations and anions and its suitability for high resolution chemical imaging by using laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS). The new high resolution mixed binding gel (HR-MBG) is based on zirconium-hydroxide and suspended particulate reagent-iminodiacetat...
