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).

Which polyacrylamide hydrogel containing 1% & 7% w/v gelatin are labeled 'Pam-?

The prepared polyacrylamide/gelatin hydrogels containing 1%, 3%, 5% and 7% w/v gelatin were coded as PAM-Gel1, PAM-Gel3, PAM-Gel5 and PAM-Gel7, respectively. All of the above hydrogels were collectively labeled as PAM-Gels. The polyacrylamide hydrogel without gelatin was abbreviated as PAM. Fig. 1.

Is pam-gel5 a cyto-compatibility polyacrylamide/gelatin hydrogel?

PAM-Gel5 possessed balanced mechanical properties and good cyto-compatibility in vitro. PAM-Gel5 showed sustained release characteristics under physiological conditions. In this work, various shape memory polyacrylamide/gelatin (PAM-Gels) hydrogels with interpenetrating double networks were synthesized via a facile one-pot method.

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.

How are shape memory polyacrylamide/gelatin (Pam-gel) hydrogels prepared?

Shape memory polyacrylamide/gelatin (PAM-Gel) hydrogels were prepared via a one-pot method. Properties of double network PAM-Gels could be tuned by altering each component content. PAM-Gel5 hydrogel exhibited the highest shape fixity and shape recovery rates. PAM-Gel5 possessed balanced mechanical properties and good cyto-compatibility in vitro.

Are PAAM hydrogels biofunctionalized?

PAAm hydrogels can be biofunctionalized with cell-adhesive molecules to interact with cells by specific interactions. [20, 21] Furthermore, they can be easily prepared in different formats, i.e., thin films, channels, or microgels. In recent years, several reviews have discussed PAAm hydrogels from different perspectives.
