Nanoplasmonics for Enhanced Fluorescence Detection of Nucleic Acids: From Fundamentals to Boosting Cancer Management

Advanced NanoBiomed Research, Volume 5, Issue 2, February 2025.
Cancer is a leading cause of mortality, prompting advancements in diagnostics and therapy. The potential of hybrid nanobiosensors, specifically fluorescent DNA probes on metal nanoparticles, to improve cancer disease management is highlighted. Owing to the plasmonic properties of metal nanoparticles, these biosensors feature improved signaling emission

New insights into the mechanisms of plant isotope fractionation from combined analysis of intramolecular 13C and deuterium abundances in Pinus nigra tree‐ring glucose

New Phytologist, Volume 245, Issue 3, Page 1000-1017, February 2025.
Summary Understanding isotope fractionation mechanisms is fundamental for analyses of plant ecophysiology and paleoclimate based on tree‐ring isotope data. To gain new insights into isotope fractionation, we analysed intramolecular 13C discrimination in tree‐ring glucose (Δi′, i = C‐1 to C‐6) and metabolic deuterium fractionation at H1 and H2 (εmet ...
