• ; microscopies; nanostructure; supramolecular hydrogel; Introduction Hydrogels, whether based on self-assembling molecules or cross-linked polymers, are useful in fields ranging from tissue engineering to drug delivery and biosensing [1][2][3][4][5]. Their high water content and soft, porous structure make them

• artefacts stresses the need for multiple orthogonal approaches when interpreting gel morphology [18]. In this study, the morphological features of imidazolium-based supramolecular hydrogel fibres incorporating two distinct fluorescent probes, namely, a zinc phthalocyanine tetrasulfonic acid (ZnPc) and a

• , indicating that hMSCs had a high viability in the supramolecular hydrogel formed by NI-Phe. Sarkar et al. synthesized amphiphilic molecules containing NI and histidine which formed fluorescent organic nanoparticles with J-aggregation in water/DMSO, exhibiting high emissivity upon aggregation. These particles

First stimuli responsive supramolecular hydrogel films based on β-cyclodextrin and adamantyl-modified chitosan derivatives have demonstrated a reversible swelling and shrinking upon changing the ionic strength [62]. At high ionic strength, the decrease in the electrostatic repulsive effect between the

• long term, a supramolecular hydrogel composed of a peptide and luminescent nanodots could be valuable for tissue regeneration based on a bioactive scaffold that can be also visualized in vivo by fluorescence microscopy. Alternatively, other potential applications could be developed in the future for
