Smart Electrospun Nanofibers for Controlled Oil‐Water Separation

open access: yesAdvanced Materials Interfaces, EarlyView.
Stimuli‐responsive electrospun nanofibers are reviewed as advanced platforms for controlled oil/water separation. The effects of surface wettability, porous structure, and external stimuli, including pH, temperature, gas, and light, on separation performance are discussed.

Theranostic Potential of an NAD(P)H‐Activatable Fluorophore: Assessing Cancer Aggressiveness and Triggering Apoptosis

open access: yesAngewandte Chemie, EarlyView.
DE‐CQ, an NAD(P)H‐activatable theranostic probe, enables the quantification of cancer aggressiveness via glucose‐stimulated fluorescence imaging and selectively induces apoptosis. Its multifaceted efficacy is demonstrated across 2D cells, 3D spheroids, and in vivo models.

Unexpected hydrated ions in the detection of sodium adduct coumarins using electrospray tandem mass spectrometry

open access: yes, 2017
A series of coumarins were analyzed using electrospray ionization quadrupole time-of-flight tandem mass spectrometry in the positive-ion mode. Unexpected hydrated ions ([M + H2O + Na] (+)) was observed upon collision- induced dissociation of the sodiated

Pyrazole‐Derived Antibacterial Compounds Effectively Treat Methicillin‐Resistant Staphylococcus Aureus Infections by Inhibiting Aspartate Transcarbamoylase

open access: yesAdvanced Science, EarlyView.
This study unveils a novel antibacterial mechanism against MRSA, in which the compound Py‐27 selectively targets and inhibits aspartate transcarbamoylase (ATCase), a key enzyme in pyrimidine synthesis. This inhibition disrupts DNA replication, induces oxidative damage, leading to potent bactericidal activity.

Kidney‐Targeted Cilastatin Nanoparticles Inhibit DPEP1‐Mediated Ferroptosis for Acute Kidney Injury Therapy

open access: yesAdvanced Science, EarlyView.
In this study, MPDA NPs were engineered to encapsulate CTT. To further increase renal accumulation of CTT, L‐serine was conjugated to the surface of the MPDA nanoparticles (CTT/MPDA@L‐Ser NPs). CTT/MPDA@L‐Ser NPs inhibit DPEP1 activity, thereby restoring ferroptosis defense mechanisms through upregulation of GPX4 and SLC7A11 expression, ultimately ...
