The ability to form functional polymeric patterning structures has important implications for the studies of cell biology, tissue engineering, and medical diagnostics. We have developed a novel enzyme-assisted photolithography (EAPL) method for spatial functionalization of hydrogels via a high throughput fashion. A bisacrylated peptide crosslinker, containing a protease cleavable amino acid seq...

in this work, hydrogel nanocomposites were synthesized by solution polymerization of acrylic acid (aa) and itaconic acid (ia) in the presence of cotton fabric. ammonium persulfate (aps) was used as the polymerization initiator in the presence of a crosslinker, methylene bisacrylamide (mba). insertion of ag followed by reduction of ag+ cations results in a hydrogel nanocomposite. the structure a...

Cells organize actin filaments into higher-order structures by regulating the composition, distribution and concentration of actin crosslinkers. Palladin is an actin crosslinker found in the lamellar actin network and stress fibers, which are critical for mechanosensing of the environment. Palladin also serves as a molecular scaffold for α-actinin, another key actin crosslinker. By virtue of it...

PURPOSE The present study deals with evaluation of crosslinked poly vinyl alcohol (PVA) as a potential disintegrant. METHODS Crosslinking of PVA was carried out using glutaraldehyde as a crosslinker, in presence of acidic conditions. The crosslinking reaction was optimized for a) polymer: crosslinker ratio; b) temperature requirement and c) reaction duration. Certain physical parameters of th...

The nanocomposites of poly (Acryl amide-co-Acrylic acid) with different contents of NaAzeolite were prepared using ammonium persulfate as an initiator and N, N′-methylenebisacrylamide as the crosslinker. The morphology was characterized by SEM and the structure ofnanocomposite materials was studied with XRD and FT-IR that showed the interaction betweenporous materials and poly (AAm-co-Aac). The...
