The interaction between nano-SiO2 and lysozyme was investigated by the method of UV-Visible  detection and fluorescence spectroscopic techniques. The thermal denaturation of lysozyme has been investigated in the presence and absence of nano-SiO2 over the temperature range (293-373) K in different buffers and pH values, using temperature scanning spectroscopy. The presence of nano-SiO2 caused the destabilization of lysozyme resulting in a decrease in the temperature of unfolding with an increase in nano-SiO2 concentration.
