Are All Alginate Dressings Equivalent?

open access: yesJournal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 113, Issue 3, March 2025.
ABSTRACT Alginate dressings are widely used in wound treatment for their healing and hemostatic properties and their capacity to drain exudate. However, a clear understanding of the heterogeneity within this class of dressings is lacking. Numerous sources of variability exist between alginate dressings: their composition (% of calcium alginate relative

DiatOmicBase: a versatile gene‐centered platform for mining functional omics data in diatom research

open access: yesThe Plant Journal, Volume 121, Issue 6, March 2025.
SUMMARY Diatoms are prominent microalgae found in all aquatic environments. Over the last 20 years, thanks to the availability of genomic and genetic resources, diatom species such as Phaeodactylum tricornutum and Thalassiosira pseudonana have emerged as valuable experimental model systems for exploring topics ranging from evolution to cell biology ...

Gold Nanoparticles Electrodeposition Onto Thick Diazonium Film for Sensitive and Long‐Lasting Hg(II) Trace Sensing

open access: yesInternational Journal of Electrochemistry, Volume 2025, Issue 1, 2025.
A new electrochemical sensor devoted to Hg(II) trace determination was developed by tailoring a hybrid organic/inorganic interface using diazonium salts and gold nanoparticles (AuNPs). The AuNPs were electrodeposited for the very first time onto glassy carbon (GC) electrodes functionalized by thick (ca. 4 nm) diazonium films.
