AB  - A simple, fast, and laboratory efficient doped P carbon nanoparticles synthesis is developed for fingerprint imaging, using 1,3-dihydroxyacetone and di-phosphorous pentoxide. Fluorescence nanoparticles, with an average size of 230 nm were obtained, without additional energy input or external heating. ATR, solid NMR, XPS and fluorescence spectroscopy revealed their surface functionalization; a reaction mechanism is proposed. Fluorescence measurements exhibited a maximum emission band at ca. 495 nm, when excited at 385 nm. The images obtained, on different surfaces such as mobile telephone screen, magnetic band and metallic surface of a credit card and a Euro banknote treated with the obtained nano-powders allows us to record positive matches, confirming that the experimental results illustrate the effectiveness of proposed method.

AB  - Carbon Dots (CDs) were obtained using a hydrothermal method and used for the detection of finger-prints through fluorescent imaging. Synthesized CDs exhibited a brightness emission at 495 nm, which was related to their structural and chemical properties. The results of detailed surface characterizations by XPS, ss-NMR and fluorescence spectroscopies, suggested that the negative charge of the functionals groups promoted electrostatic interactions between the charged CDs surface functional groups (amine, amide and carboxylic) and the secretion components present in the thin layer of fluid left on the surface upon its direct contact with human fingers. The obtained results were validated by the scientific protocol of the Police Automated Fingerprint Identification System (AFIS) based on a biometric identification.

AB  - A glassy carbon electrode (GCE) was surface-modified with carbon quantum dots (CQDs) and applied for the effective enhancement of the electrochemical signal for dopamine and uric acid determination. CQDs were prepared from graphite by a green modification of the Hummers method. They were characterized by FTIR-ATR, XPS, solid-state NMR, fluorescence and Raman spectroscopies. TPD-MS analysis was applied to characterize the functionalization of the surface. The CQDs were assembled on the glassy carbon electrode by adsorption because of the large number of carboxy groups on their surface warrants effective adsorption. The modified GCE exhibits a sensitivity that is almost 10 times better than of the bare GCE. The lower limits of detection are 1.3 mu M for uric acid and 2.7 mu M for dopamine.

AB  - In this work carbon quantum dot (CQD) nanoparticles are synthesized from D-lactose using a hydrothermal method and then they are coated with polyethylene glycol (CQDs"PEG). These particles exhibit a monodisperse spherical morphology with an average particle size of similar to 4 nm. Nuclear magnetic resonance (NMR) and Fourier transform infrared (FTIR) spectroscopy showed the presence of the hydroxyl groups from the ethylene glycol molecules grafted onto the CQDs' surfaces, which confirms that PEG was covalently attached to the nanoparticles' surfaces. Fluorescence analysis demonstrates a shift in the emission at 495 nm after PEG coating. Modified carbon dots were introduced into thermo-responsive pNIPAM microgels. The resultant pNIPAM-CQDs"PEG hybrid system exhibits interesting fluorescence properties. Transmission electron microscopy (TEM), fluorescence microscopy, and energy-dispersive X-ray (EDX) spectroscopy confirm the incorporation of CQD particles into the microgels. Finally, dynamic light scattering (DLS) analysis confirms that further hybrid microgels based on pNIPAM are thermo-responsive, with a transition temperature similar to that of a system with an ionic component.
