VIANELLO FABIO

Bionanotechnology: Starting from novel superparamagnetic nanoparticles, constituted of stoichiometric maghemite (γ-Fe2O3), synthesized in the laboratory by an innovative and simple method in the dimension range of few nanometers, new biotechnological applications are going to be explored. The new material was patented and it now under characterization by different techniques, such as HRTEM, x-ray powder diffraction, magnetization measurements, Mössbauer, FTIR and optical spectroscopy. The nanometric maghemite product is very stable as a colloidal suspension without any surface coating and it is characterized by the ability to reversibly bind specific molecules on the bare iron oxide surface. These bare stoichiometric maghemite (γ-Fe2O3) nanoparticles can be easily used to bind organic molecules, DNA and enzymes. Fluorescent magnetically drivable nanocarriers are currently prepared and characterized using different enzymes, developing new fluorescent magnetically drivable nanocatalysts. The aim of future research projects is aimed to develop new simple procedures to isolate and purify proteins and nucleic acids and to propose new biosensors, based on electrochemical and gravimetric transducers.

Food analysis: The present research line is focused on the determination of the composition of food products, providing independent, 3rd party, chemical and physical analysis on an array of food, water, cosmetic and pharmaceutical. The laboratory produces credible and accurate testing, maintains officially approved methodologies and generates reliable results that can positively impact business. The research tem offer a broad range of consulting and technical services to assist manufacturers, operators, distributors and retail providers in assuring the quality and safety of their food, beverage, pharmaceutical and cosmetic products.
