Biomass-Derived Carbon Dots as Fluorescent Probes for Label-Free Sensing of Hemin and as Radical Scavengers

Biosensors, Journal Year: 2025, Volume and Issue: 15(2), P. 105 - 105

Published: Feb. 12, 2025

Carbon dots (CDs) derived from biomass are promising fluorescent probes for specific analyte detection due to their specificity, biocompatibility, selectivity, and sensitivity. In this work, carbon were prepared hydrothermally natural material, Myrica esculenta fruits (hereafter referred as MPCDs), without adding any chemicals. The MPCDs characterized using optical, microscopic, spectroscopic methods that revealed the presence of numerous functional groups properties. exhibited exceptional characteristics such water solubility, photostability, excitation-dependent fluorescence emission, ionic stability. Transmission electron microscopy found average size was 8 nm. remarkable sensing ability hemin, with a good linearity (R2 = 0.999) lower limit 14.1 nM. demonstrated quenching-based primarily owing ground state complex formation inner filter effect. Furthermore, material excellent antioxidant potential against 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) 2,2-diphenyl-1-picrylhydrazyl radicals EC50 values 25.4 205.4 µg/mL, respectively. study suggests CDs could be used optical sensors hemin well scavenge selected radicals.

Analysis of Fluorescent Carbon Nanodots Synthesized from Spices Through Thermal Processes Treatment

Nanomaterials, Journal Year: 2025, Volume and Issue: 15(8), P. 625 - 625

Published: April 19, 2025

Spices contain abundant essential oils and active compounds, which can be difficult to introduce into living cells due their apolar, lipophilic nature. Carbon nanoparticles, produced through the Maillard reaction during food heat treatment, are small enough enter easily. This study explores how thermal processing affects formation of carbon nanodots (CNDs) in spices, revealing that higher temperatures boost CND synthesis, thus enhancing bioavailability biological effectiveness. Interestingly, turmeric black pepper enriched with CNDs notably influenced yeast fermentation, an overall increase antioxidant capacity, especially chili pepper. However, excessive occasionally reduced activity, suggesting breakdown sensitive compounds. These findings highlight potential CND-enriched spices for health nutrition applications.
