Remarkable solvent tunable aggregation caused quenching for fluorochromic chitosan based hydrogel

Detection of o‐nitro aniline by bovine serum albumin based self‐fluorescent hydrogel via FRET process

“…Strain sweep experiment reveals its susceptibility to tolerate a high strain and deformation limit is nearly 8%. Frequency sweep experiment is performed under a constant strain of 0.2%, which is lower than its deformation limit and it shows two never intersecting parameters, that is, G ′ and G ″ which signifies BG hydrogel to show a strong gelation ability 57 …”

“…Frequency sweep experiment is performed under a constant strain of 0.2%, which is lower than its deformation limit and it shows two never intersecting parameters, that is, G 0 and G 00 which signifies BG hydrogel to show a strong gelation ability. 57 The suspension of BG gel in contact with various pH aqueous buffer environments reveals the ability to enlarge and hold solvents within its elasticity ranges at room temperature. The gelation process helps in create a compact 3D structure by altering various interactions present in actual BSA protein chain resulting aggregation of the structural network.…”

Evaluation of nanofibril chitosan@8‐formyl‐7‐hydroxy‐coumarin hydrogel having distinct auto‐fluorescence efficiency: Structure–properties relation, improved antioxidant, and cellular imaging

“…The strain sweep experimentation provides G ′ > G ″ (up to 20% strain) due to the gelation of ChCm consequently, it indicates the dominating elastic nature (Figure 1c,d). Frequency sweep experimentations have been performed under the deformation range, at a constant strain of 1%; thus, G ′ > G ″ was observed due to the enhancement of angular frequency 45 . At higher frequency, due to the exposure of a solid cross‐linking network, ChCm has an elastic nature and becomes stiffer as solid‐like behavior.…”

Imidazole-based AIEgens for highly sensitive and selective detection of picric acid

“…[4][5][6][7] The ACQ phenomenon has greatly limited the scope of the practical applications of OLMs. [8][9][10][11] To overcome the disadvantages of ACQ-type OLMs, researchers in recent years have reported a large number of aggregation-induced emission (AIE)-type OLMs that show strong fluorescence in the aggregated state. [12][13][14] Mechanism study based on crystallographic analysis has shown that the origin of AIE nature could be ascribed to the supramolecular assembly of molecular species via weak noncovalent interactions hydrogen bonding, C-H⋯π interactions, and π stacking interactions.…”
