Carbon Quantum Dots from Coconut Husk: Evaluation for Antioxidant and Cytotoxic Activity

Carbon quantum dots shuttle electrons to the anode of a microbial fuel cell

“…The inherent ability of C-dots to donate and accept electrons forms the basis of the present study. This communication demonstrates the role of previously described (Chunduri et al 2016) C-dots in microbial electron transfer and their application as an electron shuttle in the anode chamber of an MFC.…”

“…2) showed that the C-dots were spherical in shape and lesser than 10 nm in diameter. Detailed structural and functional characterization of the C-dots used in this study was performed and described previously by Chunduri et al (2016). X-ray diffraction spectrum confirmed the crystalline structure and Raman spectrum indicated the graphitic constitution of the C-dots.…”

“…C-dots were synthesized in a single-step hydrothermal carbonization from coconut husk by following the procedure reported by Chunduri et al (2016). …”

“…Carbon quantum dots present an attractive option in this regard and are gaining increasing application in biosensing and bioimaging because they display excellent stable photoluminescence, high resistance to photobleaching and low toxicity (Lim et al 2015;Li et al 2012;Shi et al 2014). Moreover, their synthesis is relatively simple, inexpensive and non-toxic (Peng and Travas-Sejdic 2009;Derfus et al 2004;Chunduri et al 2016). Along with excellent water solubility and good biocompatibility, these properties make carbon dots sensitive and cost-effective candidates for fluorescent biolabels (Ding et al 2014;Zuo et al 2015;Hu 2013).…”

Ethylenediamine mediated luminescence enhancement of pollutant derivatized carbon quantum dots for intracellular trinitrotoluene detection: soot to shine

“…34 This emission behaviour is in agreement with other foregoing published multicolour imaging applications of CQDs. 34,37 So, it can be summarized that, C1 might be composed of PAHs as in order of PAH-3R > PAH-4R > PAH-5R; while, C2 might comprise of the PAHs as sequence of PAH-4R > PAH-3R > PAH-5R which are responsible for their specic emission behaviour. Both of the QDs are having lesser PAHs having lower band gap energies (PAH-5R), while the amount of PAH-4R is considerably higher in C2 than that of C1 as depicted from their emission proles.…”
