Synthesis of high quantum yield orange carbon dots as multifunctional fluorescence probe in VB12 detection and bio-imaging

Facile synthesis of long-wavelength fluorescent carbon dots: toward multifunctional applications in nitrite sensing and bioimaging

A ratiometric fluorescent probe based on peanut-shell-derived CDs and CuNCs for smartphone-assisted detection of methyl orange.

Methyl orange (MO), a refractory azo dye, can persist in aqueous environments, creating a need for rapid and reliable monitoring methods. In this work, naturally O/N-containing peanut-shell biomass was utilized as an agricultural solid-waste precursor to synthesize oxygen-containing carbon dots (CDs) via a hydrothermal...

Rationally Designed Blue-to-Green Carbon Dot Nanoplatform for Self-Calibrated Ratiometric Fluorescence Sensing of Vitamin B2

Nanomaterial-based fluorescent probes have attracted considerable attention for sensitive biomolecule detection owing to their unique optical properties, high surface-to-volume ratio and excellent surface functionality. Herein, we report rationally designed blue-to-green carbon dots (BG-CDs) as a multifunctional carb...

Zinc-doped carbon dots for hypochlorite ultrasensitive determination: from aqueous monitoring to live-cells imaging

Mustard oil-derived carbon dots for ultra trace Pb2+ detection and cell bioimaging applications

Water-soluble blue fluorescent carbon soot-carbon dots (CS-CDs) were synthesized using mustard oil through a flame deposition method. This work investigates the effect of a confined combustion environment on particle formation. While particle size remained same even when the container volume was increased fourfold, a s...

Fluorescence spectroscopy of gum arabic-derived carbon quantum dots: a green nanosensor for dantrolene determination via the inner filter effect.

Carbon quantum dots (CQDs) are promising fluorescent nanomaterials for analytical applications, but their structure-property relationships remain under-investigated, especially in biomass-derived systems. Herein, we report the ultrafast, one-pot, microwave-assisted synthesis (700 W, 4 min) of highly fluorescent CQDs fr...
