Advanced Science, EarlyView.We report a robust aerogel digital biosensor by integrating an enzyme‐mediated amorphous MOF within an aerogel matrix for on‐site pesticide detection. The enzyme‐mediated assembly strategy enables in situ tailoring of MOF into a porous amorphous structure, achieving both high stability and activity.

Infrared Spectrophotometry as a Means for Identification of Mosquitoes.
Experimental Biology and Medicine, 1953 SummaryCrude aqueous extracts of Culex molestus, Culex quinquefasciatus, and Aedes aegypti adult mosquitoes were identified by infrared spectrophotometry. The most important differences were the relative intensities of the peaks at about 6.95 and 7.2 μ, and the relative depth and shape of the broad band from about 8.6 to 10 μ.

Advanced Science, EarlyView.This study uncovers that quercetin naturally targets mitochondria. By coordinating quercetin with Fe3+, we engineer an ultrasmall cascade nanozyme (MCN) with superoxide dismutase‐catalase activities. MCN crosses the damaged blood–brain barrier, scavenges mitochondrial ROS, prevents mitochondrial DNA leakage, and blocks the cGAS‐STING pathway, thereby ...

Milk urea analytical result reliability and its methodical possibilities in the Czech Republic
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013 Control of milk urea concentration (MUC) can be used in diagnosis of the energy–nitrogen metabolism of cows. There are more analytical methods for MUC estimation and there are also discussions about their result reliability.

Degradation Mechanisms, Encapsulation‐Based Stabilization, and Analytical Detection of Vitamin A
Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT Vitamin A is an important lipid‐soluble micronutrient essential for vision, immune function, and overall growth and development. However, vitamin A is unstable and susceptible to environmental factors because of its conjugated structure and inherent chemical reactivity.
