Fabrication of Highly Fluorescent Nitrogen and Phosphorus Dual-Doped Carbon Dots for Selective Sensing of Rutin.

Based on nitrogen and phosphorus co-doped carbon dots (NP-CDs), a direct, quick, and selective sensing probe for fluorometric detection of rutin has been developed. Utilizing ethylene diamine tetra acetic acid (EDTA) as a carbon and nitrogen source and diammonium hydrogen phosphate (NH)HPO as a nitrogen and phosphorus source. The NP-CDs were synthesized in less than 3 min with a straightforward one-step microwave pyrolysis process with a high quantum yield (63.

Luminescent Carbon Dots From Biomass Waste for the Sensitive Determination of Ascorbic Acid in Tablet Dosage Forms.

Affordable and eco-friendly green spectrofluorometric (FL) methods can enhance the safety and cost-effectiveness of quality assurance and control in ascorbic acid (ASA) formulations. However, most current techniques for ASA analysis have faced challenges like complexity, delayed response times, low throughput, time-consuming procedures, and requirements for expensive equipment and hazardous chemicals for analyte modification. The study is aimed at producing natural carbon quantum dots (NACQDs) from pumpkin seed peels (PSPs), a natural waste material, using a rapid microwave-assisted method.

Garlic peel-based carbon quantum dots as a sustainable alternative for the sensitive and green spectrofluorometric quantification of molnupiravir in pharmaceutical capsules.

Searching for natural alternatives to replace environmentally harmful chemical reagents in analysis is just as crucial as finding easily accessible analytical tools. To reinforce these concepts, this study proposes a simple spectrofluorometric approach using natural carbon quantum dots (n-CQDs) as fluorescence probes for sensitive and environmentally friendly measurement of molnupiravir, an antiviral drug that was initially developed for influenza and has demonstrated potential efficacy against COVID-19. n-CQDs were synthesized using garlic peels (GP), a waste material, via a microwave-assisted method.

A Novel Ultrasensitive Second Derivative Synchronous Spectrofluorimetric Approach for the Simultaneous Analysis of the Co-Administered Antihypertensives, Telmisartan and Carvedilol in Biological Fluids and Tablets: Greenness and Blueness Assessment.

Hypertension is the predominant risk factor for cardiovascular diseases and mortality. This study presents the first method for the simultaneous analysis of the co-administered antihypertensive drugs, Carvedilol (CAR) and Telmisartan (TEL) using a fast, highly sensitive, environmentally friendly, and cost-effective second derivative synchronous spectrofluorimetric approach. The fluorescence of CAR and TEL was quantified at 243 nm and 274.

A Modified Green Star Area (MoGSA) and software to assess greenness of reactions in the chemistry laboratories.

The environmental and health impacts of chemical processes have been a growing concern, leading to the establishment of Green Chemistry principles. Introducing new metrics for the assessment of methods' greenness is crucial to evaluate the exerted efforts to conserve the environment. In this work, we introduce a Modified Green Star Area (MoGSA) and software to assess the greenness of chemical reactions in laboratory settings.
