TL;DR: Nitrogen-doped, carbon-rich, highly photoluminescent carbon dots have been synthesized for the first time from ammonium citrate under hydrothermal conditions and possess bright blue luminescence, short fluorescence lifetime, pH-sensitivity and excellent stability at a high salt concentration.

TL;DR: A green, large-scale and high-output heterogeneous synthesis of N-doped CDs was developed by reacting calcium citrate and urea under microwave irradiation without the use of any capping agents to exhibit good aqueous solubility and yellowish-green fluorescence in the solid and aqueously states.

TL;DR: These monodispersed Ag NPs could be a promising alternative for the disinfection of multidrug-resistant bacterial strains, and they showed negligible cytotoxicity and good biocompatibility toward Cos-7 cells.

TL;DR: It was determined that organic molecules, such as succinic acid, lactic acid, malic acid, and glutathione, which are generated in metabolism process, played important role in the reduction of gold ions, and it was found that the gold nanoplates exhibited plasmonic property with prominent dipole infrared resonance in near-infrared region, indicating their potential in surface plAsmon-enhanced applications, suchAs bioimaging and photothermal therapy.

TL;DR: In this paper, a method for synthesizing nitrogen-doped carbon quantum dots based on calcium citrate and urea microwave reaction is presented, which consists of the steps of weighing a certain amount of calcium citrates and Urea, adding urea into a proper amount of water, stirring uniformly to obtain a suspension, rotating for 3-10min in a microwave oven at 400-800W, and drying the reaction product in a vacuum drying oven at 40-80 DEG C for 0.5-5h.
