Study of properties of nanoparticles
and nanocomposites in liquid media
Objects of our investigations belong to a principally new class of composite materials that have emerged due to latest achievements in synthesis, bioadaptation and bioconjugation of nanoparticles. These are colloidal solutions of fluorescing nanoparticles (nanodiamonds (ND), carbon quantum dots (CQD)). These objects are of interest both from fundamental and practical points of view. Unique fluorescent properties of carbon quantum dots and nanodiamonds, their safety and non-toxicity allow their active use as optical biosensors. Due to developed multifunctional surface of ND and possibility of its modification this material has a very promising perspective for wide application in biology and medicine for adsorption and targeted drug delivery as well.
