definition of polyacrylamide hydrogel - nci drug

Definition of polyacrylamide hydrogel - NCI Drug

A transparent, biocompatible, non-resorbable, homogenous hydrogel containing 975% apyrogenic water and 25% of the cross-linked, synthetic polyacrylamide. Upon injection into the urethral submucosal tissue, the polyacrylamide hydrogel serves as a bulk forming agent and may possibly increase the strength of the urethral sphincter and thereby prevent or decrease stress-induced urinary incontinence.

An electro-responsive hydrogel for intravascular

These stimuli can change the hydrogel shape in a predefined way. It could make them capable of adaptation to patient-specific anatomy even post-implantation. This is the first paper aiming to describe in vivo studies of an electro-responsive, Pluronic F127 based hydrogel, for intravascular applications.

Nanoparticle-Hydrogel Composites: From Molecular

Calculating G from Equation (1) yields G = υ k B T, thus providing a direct interpretation of how changes in υ, as can be experienced in NP–hydrogel networks, affect the mechanical properties.Equation (1) also provides the basis for the interpretation of how molecular parameters affect the swelling equilibrium of hydrogel (e.g., minimum free energy as adjusted through changes in φ 2 and

Predictions of Thermo‐Mechanical Properties of Cross

To be clear, by definition, a hydrogel sample with a DOC of 0% (i.e., the un‐crosslinked hydrogel) does not correspond to a sample containing unreacted AAm monomers and MBAm cross‐linkers, but rather corresponds to a sample in which the pre‐polymerized PAAm oligomers and MBAm cross‐linkers have not yet reacted.

water soluble polymers for pharmaceutical applications

Water Soluble Polymers for Pharmaceutical Applications

Advances in polymer science have led to the development of novel drug delivery systems. Some polymers are obtained from natural resources and then chemically modified for various applications, while others are chemically synthesized and used. A large number of natural and synthetic polymers are available. In the present paper, only water soluble polymers are described.
