Early Pancreatic Cancer Diagnosis via Ultrasensitive THz Toroidal Metasensing

open access: yesAdvanced Photonics Research, EarlyView.
This study introduces a revolutionary terahertz metasurface biosensor using gold nanoparticles to boost sensitivity. It achieves precise detection of ultra‐low biomarker concentrations (1–1000 pg mL−1) with a 97.6 GHz/RIU sensitivity through optimized antibody binding.

Dual‐Functional Ingestible Passive Capsules for High‐Throughput Intestinal Sampling with Sealed Containment and Targeted Drug Delivery

open access: yesAdvanced Robotics Research, EarlyView.
To address challenges in high‐throughput intestinal sampling with sealed containment and target drug delivery, we developed a dual‐functional ingestible passive capsule with a dual‐triggered control system based on pH‐response and mechanical actuation.

5,7‐Membered Cyclometallated Gold(III) Complexes with Pyridine‐Phenyl‐Oxazoline N^C^N Ligands as Catalysts for Organic Transformation Reactions Under Silver‐Free Conditions

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A series of 5,7‐membered cyclometallated gold(III) complexes with N^C^N tridentate ligands are prepared via transmetalation of pyridine‐phenyl‐oxazoline ligand‐containing organomercury compounds with potassium gold(III) chloride (KAuCl4) for catalysis.

On the Role of MWCNTs for the Effective Detection of Glucose Using MWCNTs/NiO/MWCNTs Stacks on Carbon Paper Electrodes

open access: yesAdvanced Sensor Research, EarlyView.
This study deciphers the mechanism of enhanced glucose detection using multiwalled carbon nanotubes and nickel oxide stacks (MWCNTs/NiO/MWCNTs) on commercially available carbon paper electrodes. We demonstrate the role of MWCNTs where the defects enrich the electrocatalytic activity when they come in contact with the glucose molecule for its selective ...

Discovery of Surface‐Induced Resonance Shift of 4‐Nitrophenol Enabling Direct Monitoring of an Enzymatic Reaction

open access: yesAdvanced Sensor Research, EarlyView.
A surface‐modified porous silica consisting of acetyl‐protected mannose residue and co‐precipitated urea compounds promotes a distinct resonance shift of 4‐nitrophenol under neutral conditions upon interaction, that is revealed by confocal Raman spectroscopy. The quinone‐type resonance structure is favored over the phenol‐type.
