On‐Paper Enzyme‐Linked and Metal‐Linked Immunosorbent Assays for Low‐Cost Decentralized Testing of Carcinoembryonic Antigen

open access: yesAnalysis &Sensing, EarlyView.
On‐paper enzyme‐linked and metal‐linked immunosorbent assays (p‐ELISA and p‐MeLISA, respectively) were developed for the assay of carcinoembryonic antigen (CEA) in serum. These approaches are based on bio‐conjugated paper disks as analytical platform.

Fluorescence‐Based Detection of Hg(II) and Cr(VI) Using Nitrogen‐Sulfur Codoped Carbon Nanodots in their Pristine and Aminosilica‐Embedded Forms

open access: yesAnalysis &Sensing, EarlyView.
Hg(II) quenches the fluorescence of free N, S‐doped carbon nanodots (CNDs), while Cr(VI) quenches selectively the fluorescence of the same CNDs when confined within an aminosilica matrix. The silica matrix acts as a favorable inorganic scaffold for embedding CNDs, thereby enabling selective fluorescence‐based detection of Cr(VI) in the presence of Hg ...

Ferrocene‐Based Kickers for the Radical Polymerization of Vinyl Chloride Under Suspension Conditions: Improvement of the Process

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT Polyvinyl chloride (PVC) is primarily manufactured via radical suspension polymerization of vinyl chloride monomer (VCM). Previously, dual‐component ferrocene (Fc)‐based kickers have been shown to enhance this process by facilitating the controlled decomposition of organic peroxides into radicals during the initiation step.
