Characterization of titanium dioxide nanoparticles imprinted for tyrosine by flow field-flow fractionation and spectrofluorimetric analysis

Nanoparticles (NPs) of TiO2 are synthesized in the presence of tyrosine (tyr) to realize the imprinting. Using flow field-flow fractionation (FlFFF), the NPs are purified from free tyr, and size-separated. Fluorescence characterization of the fractionated NPs confirms the existence of TiO2 NPs-tyr association with possible imprinting.
