What are the applications of polyacrylamide based hydrogels?

In polyacrylamide (Aam) based hydrogels, plenty of applications has been found. Cross-linked polymers which can imbibe a large amount of water can be used in various fields such as biotechnology, biomedical engineering, food industry and separation process.

What is cross-linking method in polyacrylamide based hydrogels?

Cross-linking method: In this method, a chemically covalently bond is formed between the polymeric chains due to the addition of a cross-linking agent. The polyacrylamide-based hydrogels commonly use N,N’-tetramethylenebisacrylamide as a chemical cross-linker. High and uniform cross-linking is a result of chemically cross-linked hydrogels.

Are polyacrylamide hydrogels a 2d-model soft substrate?

Polyacrylamide (PAAm) hydrogels are widely adopted as 2D-model soft substrates for investigating cell-material interactions in a controlled in vitro environment.

Are polyacrylamide hydrogels a good candidate for clinical research?

The clinical aspects of the polyacrylamide are corroborated by the cell viability, proliferation and migration. Thus, polyacrylamide hydrogels are emerging candidates, precisely illuminated in the review, which can be an influential highlight designed for upcoming research.

Is polyacrylamide hydrogel a viable cartilage replacement material?

Nano-composites of polyacrylamide hydrogel with CNTs and TiO 2 serve as viable cartilage replacement material with non-toxicity, desired bio-activity and better mechanical properties over most existing replacement materials .

Can polyurethane & polyacrylamide hydrogels be used as cross-linking agents?

The IPN of polyurethane (PU) and polyacrylamide (PAM) was obtained by mixing them together with their respective cross-linking agents (vinylpyrrolidone and methylenebisacrylamide) followed by exposure of the mixture to UV radiation. This was an effort by Kim et al. to enhance the applicability of PU hydrogels.
