Iron Single-Atom Catalyst Boosting Dried Blood Spots Digestion for High-Throughput Detection of Arsenic and Cadmium

Abstract Herein, a novel Fenton-like digestion strategy has been developed for undiluted, rapid, and high-throughput digestion of DBS samples. The key of this strategy is the development of a blood collection card loaded with iron single-atom catalysts (Fe-SACs). Then, approximat...

An All-in-One Optical Emission Platform for On-Site Sensitive Detection of Selenium in Selenium-Enriched Food: Integrating Digestion, HS-SPME, and Microplasma OES

Abstract The narrow margin between selenium (Se) deficiency and toxicity demands rapid and reliable methods for monitoring Se levels in Se-enriched foods. In this work, we present an all-in-one optical emission platform that integrates in situ sample digestion, derivatization wit...
