A Universal Approach to Anchoring Chromophores onto Magnetic Scaffold for Achieving Easily Recyclable Heterogeneous Photocatalytic Systems

Advanced Science, EarlyView.
The practical application of chromophores such as porphyrins, coumarins, anthraquinones, and pyrene derivatives in photocatalysis is severely limited by catalyst stability and reusability. In this work, a simple and universal strategy is presented for preparing highly efficient and recyclable heterogeneous photocatalysts for the oxidative coupling of ...

Machine learning meets mass spectrometry: a focused perspective [PDF]

arXiv
Mass spectrometry is a widely used method to study molecules and processes in medicine, life sciences, chemistry, catalysis, and industrial product quality control, among many other applications. One of the main features of some mass spectrometry techniques is the extensive level of characterization (especially when coupled with chromatography and ion ...

Characterization of protein complexes using chemical cross-linking coupled electrospray mass spectrometry [PDF]

arXiv, 2016
Identification and characterization of large protein complexes is a mainstay of biochemical toolboxes. Utilization of cross-linking chemicals can facilitate the capture and identification of transient or weak interactions of a transient nature. Here we describe a detailed methodology for cell culture based proteomic approach. We describe the generation

Fast pH‐Driven Solubilization Method of Realgar (As4S4) to Reduce the Toxicity of Arsenic [As(III)] for Medicinal Purposes

Advanced Science, EarlyView.
Arsenic trioxide transformed acute promyelocytic leukemia therapy and shows promise against HIV. A new method to solubilize the mineral realgar produces different arsenic species depleting the main arsenic target, nuclear PML protein, and retaining effects on leukemic and HIV reservoir cells, while minimizing off‐target damage.

Artificial Intelligent‐Enhanced Metabolite Profiling for Intraoperative IDH1 Genotyping in Glioma Using an Orthogonally Responsive SERS Probe

Advanced Science, EarlyView.
This study presents a novel approach for intraoperative identification of the IDH1 genotype in glioma patients using a surface‐enhanced Raman scattering (SERS) probe to measure glutathione and hydrogen peroxide. By integrating AI‐driven deep learning algorithms, the method achieves rapid and accurate genotype differentiation, offering the potential to ...

Clinical Application of Ambient Ionization Mass Spectrometry.

Mass Spectrometry, 2017
Ambient ionization allows mass spectrometry analysis directly on the sample surface under atmospheric pressure with almost zero sample pretreatment. Since the development of desorption electrospray ionization (DESI) in 2004, many other ambient ionization

A new emitter for electrospray and electrohydrodynamic jet printing [PDF]

arXiv
We propose using a dielectric beveled nozzle for electrospray and electrohydrodynamic jet printing. This nozzle stabilizes the liquid ejection of low-conductivity liquids, considerably reducing the minimum flow rate below which the flow becomes unstable. This translates into a significant reduction of the minimum jet diameter.

Multi‐Omics and ‐Organ Insights into Energy Metabolic Adaptations in Early Sepsis Onset

Advanced Science, EarlyView.
This study shows that patients at risk of sepsis have a distinct metabolite and lipid signature, including serine and aminoadipic acid, in their serum before clinical diagnosis. A mouse model of sepsis with a compatible serum signature reveals underlying metabolic changes, including mitochondrial adaptation, altered serine‐dependent purine metabolism ...
