An emissive and pH switchable hydrazone-based hydrogel.

چکیده
A serendipitous discovery has led to a new hydrazone-based low molecular weight fluorescent super-hydrogelator. The gelation and emission properties can be switched "ON" and "OFF" using pH, enabling the sensing of biogenic amines emanating from spoiled cod.

pH-responsive and switchable triplex-based DNA hydrogels.
New methods for the preparation of reversible pH-responsive DNA hydrogels based on Hoogsteen triplex structures are described. One system consists of a hydrogel composed of duplex DNA units that bridge acrylamide chains at pH = 7.4 and undergoes dissolution at pH = 5.0 through the reconfiguration of one of the duplex bridging units into a protonated CG·C+ triplex structure. The second system co...

New methods for the preparation of reversible pH-responsive DNA hydrogels based on Hoogsteen triplex structures are described. One system consists of a hydrogel composed of duplex DNA units that bridge acrylamide chains at pH 1⁄4 7.4 and undergoes dissolution at pH 1⁄4 5.0 through the reconfiguration of one of the duplex bridging units into a protonated CG$C triplex structure. The second system...
متن کاملTransforming polyethylenimine into a pH-switchable hydrogel by additional supramolecular interactions.
Attaching a self-complementary zwitterionic supramolecular binding site to the amino groups of polyethyleneimine leads to a pH switchable hydrogel as dimerization of the zwitterions introduces additional crosslinks between the polymer chains. This gel responds to both the addition of either acid or base, as only the zwitterion can self-assemble but neither the protonated or deprotonated form.
متن کاملA fast pH-switchable and self-healing supramolecular hydrogel carrier for guided, local catheter injection in the infarcted myocardium.
Minimally invasive intervention strategies after myocardial infarction use state-of-the-art catheter systems that are able to combine mapping of the infarcted area with precise, local injection of drugs. To this end, catheter delivery of drugs that are not immediately pumped out of the heart is still challenging, and requires a carrier matrix that in the solution state can be injected through a...
متن کاملA Smart pH-Responsive Three Components Luminescent Hydrogel
In this study, we report a novel three-component luminescent hydrogel, which is composed of amino acid derivatives (N,N'-di valine-3,4,9,10-perylenetetracarboxylic acid, NVPD), riboflavin (RF), and melamine (MM). The three-component hydrogel is attributed to multiple hydrogen bonds and the strong π-π stacking interaction between these molecules. Based on the strong hydrogen bonding of the gelat...
