Silicon and carbon quantum dots

Synthesis of silicon and carbon dots with high quantum fluorescence yield for bioimaging and chemical sensors

In our laboratory we synthesize carbon flurooxide mesoparticles by electrochemical etching of 3C-SiC bulk polycrystalline substrate, carbon nanodots from urea and citric acid and glucose-ethylenediamine nanoparticles by solvothermal

carbonization, silicon nanoparticles by electrochemical etching of Si substrates. The main area applications: biosensors based on photoluminescence of Si nanoparticles to detect glucose, urea and heavy metals; photoluminescent sensors for recognition of strong alcoholic beverages based on carbon nanoparticles, fluorescent bioimaging of living and tumor cells, photoluminescent pH meter.
