Water-Based Microwave-Assisted Digestion Method for Electrochemical and Chromatographic Determination of Total Fluoride Ions in Toothpaste Samples

open access: yesApplied Sciences, 2023
Fluoride ions are the major constituents of dental products because they prevent cavities through bacterial growth inhibition. However, excessive consumption of fluoride ions results in fluorosis, thereby causing tooth staining and roughness.

Microwave digestion for microbes v1

open access: yes, 2022
Before conducting inductively coupled plasma mass spectrometry (ICP-MS), all samples containing organic compounds need to be digested in order to eliminate all organic parts. Microwave digestion is a commonly used method for organism digestion. This protocol describes how to conduct microwave digestion on microbes.

Ferritin‐Doped Nanoparticles Triggered Tumor‐Specific Darkening for Enhanced Photothermal Tumor Ablation and Immune Activation

open access: yesAdvanced Healthcare Materials, EarlyView.
Ferritin‐doped hybrid nanoparticles triggered accurate tumor‐specific hemorrhage for enhanced in situ photothermal therapy and evoked anti‐tumor immunity. Notably, HFn/GA‐Fe specifically induced tumor hemorrhage 12 h after intravenous injection, resulting in visible color darkening. Through photoacoustic imaging, tumor vessels could be clearly observed
