Hydrogen production using electrocatalytic water splitting provides encouraging innovation for endurable and clean energy generation as option in contrast to traditional energy sources. Improvement of exceptionally dynamic electrocatalysts is of...
The non-equilibrium liquid structure was achieved by interfacial jamming of pillar[5]arene carboxylic acid (P[5]AA) mediated by hydrogen bonding interactions. The assembly was reversibly modulated via jamming to unjamming transition thus...
In view to develop an autonomous lab-on-a-chip device for detection of toxins without using any spectroscopic or electrochemical equipment, self-powered enzyme micropumps were fabricated via layer-by-layer assembly of enzymes and polyelectrolytes. The thin film-based enzyme micropumps turned on fluid flow in the presence of respective substrates in a concentration-dependent manner, and the rate of the enzymatic reaction was the key for maneuvering the fluid flow. Furthermore, the newly engineered enzyme-based micropumps were able to detect toxic metals and organophosphorus pesticides by modulating the fluid flow speed as the rate of the enzymatic reaction was altered by the presence of inhibitors. Thus, by regulating fluid flow in a micropump, low concentrations of analytes (e.g., target biomarkers and inhibitors) in biological fluids can be quantitatively identified for testing in a resource-constrained environment.
We report the fabrication of pillar[5]arene (P[5]A) stabilized MCs via the self-assembly and crosslinking of P[5]A nanoaggregates at the liquid–liquid interface. These P[5]A MCs microengines turn on fluid flow in the presence of paraquat (PQ) due to host–guest molecular recognition.
A valveless micropump was designed using dynamic supramolecular interaction between beta-cyclodextrin (β -CD) and benzimidazole (BzI). It shows flow reversal in response to pH change. A L-shaped microchannel was used...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
