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.

Why are polyacrylamide hydrogels used in mechanobiology?

Polyacrylamide (PAA) hydrogels are now widely used in mechanobiology because the well-defined available protocols allow a robust and reproducible control of substrate stiffness within a physiological range. However, several assays require hydrogels inside traditional plastic substrates and the current methods remain relatively tedious.

Which acrylamide kits are available for hand casting polyacrylamide gels?

Acrylamide powders, premixed acrylamide/bis powders, and premixed acrylamide/bis solutions are offered for handcasting polyacrylamide gels. Standard and alternative cross-linkers and catalysts are available. TGX FastCast acrylamide kits for hand casting polyacrylamide gels enable fast, easy casting and produce long-life gels.

Can Paa hydrogels be used inside polystyrene multiwell plates and Petri dishes?

However, several assays require hydrogels inside traditional plastic substrates and the current methods remain relatively tedious. Here, we present a simple and direct fabrication technique that successfully attaches PAA hydrogels inside polystyrene multiwell plates and Petri dishes of different sizes.

How to prepare a nanocomposite hydrogel based on gold precursor and acrylamide monomers?

A new approach to prepare a nanocomposite hydrogel based on gold precursor and acrylamide monomers is presented. The preparation of nanocomposite hydrogel was achieved using the physical phenomenon of localized surface plasmon resonance process (LSPR) exhibited by plasmonic nanoparticles.

How are PAAM hydrogels polymerized?

PAAm hydrogels were polymerized on the sacrificial templates and placed in glacial acetic acid to dissolve the PMMA microspheres, leaving the 3D PAAm scaffolds intact. This method can also be employed to produce feature sizes down to single-cell level (3 µm) of very soft hydrogels (1 kPa).
