Abstract

The differences in observed properties considering a material in its bulk state and its nanoscale are possibly the most striking and fascinating feature of nanotechnology. Carbon dots are carbon-based nanomaterials that present fluorescence when smaller than 10 nm, but may fluoresce after treatment of its surface considering particles of the order of until 100 nm. Interestingly, the wavelength at which the fluorescence occurs is dependent on the particle size. Thus, it is possible to modulate the fluorescence controlling the size of the carbon dots, which have great potential for application in photocatalysis, bioimage, optoelectronics and sensors, being possible to functionalize these materials, aiming an application in vivo, in order to increase its biocompatibility.The hydrothermal syntheses have attracted interest for obtaining the carbon dots, being a simple, cheap and efficient technique. Moreover, it is possible to obtain materials with high homogeneity and controlled morphology and size, factors that will influence the fluorescence.Thus, the present work aims to study the influence of the conditions of hydrothermal synthesis in the fluorescence of carbon dots, perform the functionalization of this material and evaluate the ability to in vivo use of the material by hemolytic trials.
