Surface charge dictates the mechanism of cellular uptake of fluorescent amine passivated carbon dots

Author(s): Clermont-Paquette A; Fuoco G; Brancheriau CR; Piekny A; Naccache R;

The surface charge of carbon dots (CDs) governs cellular uptake; however, studies seldom compare CDs with similar physico-chemical properties thereby introducing confounding variables. Here, we investigate how the surface charge of amine-passivated carbon dots with similar optical and chemical properties influences their uptake in human cells. We synthesi ...

A Zirconium-Based Metal-Organic Framework as an Effective Green Catalyst for the Synthesis of Biodiesel

Author(s): P Duarte M; Diniz CV; Bicalho HA; Naccache R; Howarth AJ;

CAU-28 (CAU = Christian-Albrechts-University) is a zirconium-based metal-organic framework (MOF) that features a bio-renewable linker (furan-2,5-dicarboxylic acid) and can be obtained through a green synthesis. In this work, we report an optimized synthesis of CAU-28, substantially enhancing the yield from 2 to 53 %. Moreover, taking advantage of the high ...

Emerging hazardous chemicals and biological pollutants in Canadian aquatic systems and remediation approaches: A comprehensive status report

Author(s): Adeola AO; Paramo L; Fuoco G; Naccache R;

Emerging contaminants can be natural or synthetic materials, as well as materials of a chemical, or biological origin; these materials are typically not controlled or monitored in the environment. Canada is home to nearly 7 % of the world's renewable water supply and a wide range of different kinds of water systems, including the Great Lake, rivers, c ...

Electroconductive Collagen-Carbon Nanodots Nanocomposite Elicits Neurite Outgrowth, Supports Neurogenic Differentiation and Accelerates Electrophysiological Maturation of Neural Progenitor Spheroids

Author(s): Lomboni DJ; Ozgun A; de Medeiros TV; Staines W; Naccache R; Woulfe J; Variola F;

Neuronal disorders are characterized by the loss of functional neurons and disrupted neuroanatomical connectivity, severely impacting the quality of life of patients. This study investigates a novel electroconductive nanocomposite consisting of glycine-derived carbon nanodots (GlyCNDs) incorporated into a collagen matrix and validates its beneficial physi ...

Ratiometric Sensing of Glyphosate in Water Using Dual Fluorescent Carbon Dots

Author(s): Clermont-Paquette A; Mendoza DA; Sadeghi A; Piekny A; Naccache R;

Glyphosate is a broad-spectrum pesticide used in crops and is found in many products used by industry and consumers. Unfortunately, glyphosate has been shown to have some toxicity toward many organisms found in our ecosystems and has been reported to have carcinogenic effects on humans. Hence, there is a need to develop novel nanosensors that are more sen ...

Engineering the Surface Chemistry and Morphology of Polymeric Carbon Nitrides Towards Greener Heterogeneous Catalysts for Biodiesel Synthesis

Author(s): de Medeiros TV; Macina A; Bicalho HA; Naccache R;

Biodiesel remains one of the most promising alternatives to replace fossil fuel-derived petrodiesel. Nonetheless, conventional biodiesel synthesis relies on homogeneous alkali-based catalysts that involve long and tedious purification steps , increasing biodiesel production costs. Heterogeneous catalysts have emerged as promising alternatives to circumven ...

Tuning residual chirality in carbon dots with anti-microbial properties

Author(s): Victoria F; Manioudakis J; Zaroubi L; Findlay B; Naccache R;

Chirality remains a critical consideration in drug development and design, as well as in applications of enantioselective recognition and sensing. However, the preparation of chiral nanomaterials requires extensive post synthetic modifications with a chiral agent, coupled with extensive purification. This limits the use and application of chiral nanomater ...

Green synthesis of carbon dots and their applications

Author(s): Chahal S; Macairan JR; Yousefi N; Tufenkji N; Naccache R;

Carbon dots (CDs) are nanoparticles with tunable physicochemical and optical properties. Their resistance to photobleaching and relatively low toxicity render them attractive alternatives to fluorescent dyes and heavy metal-based quantum dots in the fields of bioimaging, sensing, catalysis, solar cells, and light-emitting diodes, among others. Moreover, t ...
