DNA Origami‐Templated Aptamer Chiral Structures Realize Cellular Enantioselectivity

Advanced Materials, EarlyView.
Aptamers displayed on tubular DNA origami nanostructures in defined chiral orientations (left‐ or right‐handed) exhibit enantioselective interactions with cell surface target proteins. While the right‐handed configuration supports only transient binding, the left handedness energetically favors protein dimerization and promotes subsequent ...

Chiral sulfide and achiral sulfonic acid cocatalyzed enantioselective electrophilic tandem selenylation semipinacol rearrangement of allenols

Nature Communications
A highly enantioselective electrophilic selenylation/semipinacol rearrangement of allenols has been developed, which is enabled by the cooperative catalysis of a chiral sulfide and an achiral sulfonic acid.

Neutral‐pH Electropolymerization of Aniline on Hierarchically Porous Laser‐Induced Graphene Electrodes for Dual Biosensing

Advanced Materials Technologies, EarlyView.
Neutral‐pH electropolymerization of aniline on laser‐induced graphene (LIG) produces stable, brush‐like polyaniline coatings without requiring acidic conditions. The resulting PANI–LIG electrodes exhibit enhanced electroactive surface area, efficient charge transfer, and dual sensing capability for β‐blockers and pH, providing a scalable platform ...

Mode‐dependent Far‐field Radiation of Circularly Polarized Light by a Single Plasmonic Nanohelix

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
The numerical simulations explored the chiroptical response and far‐field radiation behaviors of single plasmonic nanoantennas transitioning into helical structures. This study highlights the ability of these plasmonic nanohelices to regulate the far‐field directionality of radiation power and circular polarization in plasmon‐exciton coupled systems ...

Enantioselective Esterification of Ibuprofen under Microwave Irradiation

Molecules, 2013
Enantioselective esterification of ibuprofen has been successfully carried out in an organic solvent catalyzed by recombinant APE 1547 (a thermophilic esterase from the archaeon Aeropyrum pernix K1). Here we used microwave irradiation (MW) as the mode of
