A New Route to Crystalline Hydrogels, Guided by a Phase Diagram

Cell-penetrating peptides released from thermosensitive nanoparticles suppress pro-inflammatory cytokine response by specifically targeting inflamed cartilage explants

“…10,11,25,26 Briefly, the nanogel compositions described in Table 1 were formed by dissolving 768.5 mg NIPAm, MBA if required, and AMPSA in 30 ml degassed MilliQ water in a three-neck round bottom flask. If DMHA was required it was pre-dissolved in 10 ml of dimethyl sulfoxide (DMSO).…”

A novel two-level microstructured poly(N-isopropylacrylamide) hydrogel for controlled release

“…3b it was calculated, using the software supplied by the calorimeter manufacturer, that the LCST of the MC gel was 33.3°C, which was slightly lower than that of the PNIPAAm hydrogel, 33.9°C. Hu et al reported that the PNA particles showed a phase behavior similar to that of a pure PNIPAAm gel with a slightly higher phase transition temperature, around 35°C [30]. Here, the LCST of acrylated PNA microgels shifted to a lower value (32.8°C), because the grafting of acrylate groups moved the delicate balance in the microgels slightly in the hydrophobic direction.…”

“…First, PNA microgels were prepared according to the previously reported literature [30]. Briefly, 3.8 g NIPAAm, 200 mg allylamine, 131.5 mg MBAAm and 75.5 mg SDS were dissolved in 230 ml H 2 O and nitrogen was bubbled through for 30 min to remove oxygen.…”

Photocurable Polymer Nanocomposites for Magnetic, Optical, and Biological Applications

“…Structural color can be used for sensing applications that require a response to physical environmental conditions such as temperature [83]- [87], pH [88], [89], solvent exchange [90], [91], and pressure [92]. Hu and coworkers prepared temperature-responsive soft core/shell PC microspheres through photopolymerization and microfluidic fabrication [93].…”
