A Polyoxometalate—Carbon Nanotube Enhanced Electrochemical Sensor for Aptamer‐Based Diagnostics

Advanced Sensor Research, EarlyView.
The high electroactive surface area of multi‐walled carbon nanotubes decorated with aptamer‐functionalized polyoxovanadate units enables a ≈1000‐fold increase in peak current response for a model diclofenac detection in aqueous solution compared to unmodified platinum microelectrodes.

The regioselective synthesis of spirooxindolo pyrrolidines and pyrrolizidines via three-component reactions of acrylamides and aroylacrylic acids with isatins and α-amino acids

Beilstein Journal of Organic Chemistry, 2014
The regioselective three-component condensation of azomethine ylides derived from isatins and α-amino acids with acrylamides or aroylacrylic acids as dipolarophiles has been realized through a one-pot 1,3-dipolar cycloaddition protocol.

A Mass Spectrometry Approach Reveals Fatty Acid Isomerism in Tomato Cold Tolerance

Advanced Science, EarlyView.
An enhanced mass spectrometry approach reveals fatty acids (FAs) and FA isomers that are critical for tomato cold tolerance. Applying specific FA isomers can partially rescue cold sensitivity in tomato mutant plants, highlighting the importance of FA isomers in plant cold stress adaptation.

Super‐Resolution Compatible DNA Labeling Technique Reveals Chromatin Mobility and Organization Changes During Differentiation

Advanced Science, EarlyView.
A novel chromatin‐labeling probe is developed to investigate chromatin mobility during differentiation. The silicon rhodamine–conjugated dCTP is efficiently delivered into iPSCs and NSCs using a synthetic transporter. Super‐resolution microscopy and single‐particle tracking show decreased chromatin mobility during differentiation.

Mechanical Cues Regulate Cargo Sorting and Export at the Golgi

Advanced Science, EarlyView.
A pathway is identified linking extracellular matrix stiffness to secretion via Src–FAK–AMPK–GBF1 signaling. Golgi‐localized GBF1 acts as a mechanotransducer whose phosphorylation controls post‐Golgi cargo sorting toward secretion or lysosomal degradation.

Steric‐Adaptive Biocatalysis: Imine Reductase‐Mediated Dynamic Kinetic Resolution for Atroposelective Synthesis of Hindered Biaryl Amines

Advanced Science, EarlyView.
An unusual IRED platform is reported, enabling efficient DKR via reductive amination without any evolutionary engineering. The system accommodates extremely sterically demanding substrates, including naphthyl and quinoline derivatives, delivering naphthyl‐aryl and quinoline‐aryl amine atropisomers with excellent efficiency and stereocontrol (over 80 ...
