Dissociation Constant (Kd) Measurement for Small‐Molecule Binding Aptamers: Homogeneous Assay Methods and Critical Evaluations

Small Methods, EarlyView.
The characteristics of aptamer is most commonly represented by the dissociation constant (Kd), which is critical for aptamer optimization. Here, the assays used to evaluate Kd, including labeled and label‐free assays, are evaluated and suggestions are made to ensure that true values are obtained, while other methods are cautioned.

High‐throughput Photoactive Magnetic Microrobots for Food Quality Control

Small Methods, EarlyView.
Magneto‐photocatalytic Bi₂O₂CO₃@Fe₃O₄ microrobots enable automated antioxidant detection in food. Under UV light, they generate reactive oxygen species that oxidize a colorless dye into a green radical cation, with antioxidants inhibiting dye oxidation.

Low‐Intensity Focused Ultrasound‐Responsive Nanobubbles Enhance Thrombus Targeting and Penetration for Highly Effective Thrombolytic Therapy

Small Structures, EarlyView.
Low‐intensity focused ultrasound (LIFU)‐responsive nanobubbles (PAF@M) specifically target thrombus sites and penetrate thrombi under LIFU stimulation. Meanwhile, the liquid–gas phase transition of perfluoropentane and the release of nitric oxide synergistically enhance ultrasonic cavitation to destroy thrombus structure, providing a safe and effective

Nanoparticle‐enhanced dielectric oils for improved electrical insulation: Comparison of MgO, Al2O3, and SiO2‐based dielectric nanofluids

High Voltage, EarlyView.
Abstract This study provides comprehensive and quantitative assessments of the electrical insulation, viscosity, thermal conductivity, flash point, acidity, and stability of dielectric nanofluids. In the experiment, naphthenic mineral oil was chosen as the base fluid. MgO, Al2O3, and SiO2 were preferred as nanoparticles.
