Investigation of the interaction between colloidal TiO2 and bovine hemoglobin using spectral methods

Investigation of Antimicrobial Activity of Grapefruit Seed Extract and Its Application to Air Filters with Comparison to Propolis and Shiitake

“…However, the angle was smaller than 20° on the GSE air filters, on which the bacterial culture quickly soaked in as it contacted the filter without a film for attachment. This indicates that a bacteria culture can be easily contacted to GSE natural product, which probably leads to an enhancement of the antimicrobial activity of the GSE air filter because the wettability of the antimicrobial filter surfaces is known to be highly related to its antimicrobial activity in previous literatures (Wang et al, 2008;Necula et al, 2009;Compagnoni et al, 2012;Agrawal et al, 2013). Therefore, the high wettability of the bacteria culture, as well as the inherent superior antimicrobial activity of GSE, ensured that the GSE natural product was an excellent agent for application to antimicrobial air filters.…”

Interaction between titanium dioxide nanoparticles and human serum albumin revealed by fluorescence spectroscopy in the absence of photoactivation

“…Thus, both van der Waals force and electrostatic interaction existed in the TiO 2 NPs-HSA interaction. Furthermore, hydrogen bonds partly occurred between hydroxyl groups on TiO 2 NPs surface and the protonated amino groups in the protein [11,34]. As we know, the question of how thermodynamic parameters relate to structural detail on the change from one equilibrium state to another is one that occupies a central position in biophysical study [35].…”

“…These potential effects on biological systems and mechanisms were commonly investigated at the angle of tissue distribution [7,8], cell adsorption and toxicity [9,10]. However, investigations on TiO 2 NPs interaction with biomacromolecules, which proved to be an effective way to elucidate potential physiological effect of inorganic nanoparticles [11], are still rare.…”

Effects of nano-sized silicon dioxide on the structures and activities of three functional proteins

“…As a carrier of oxygen, Hb transports oxygen from the lungs or gills to the rest of the body where it releases the oxygen for cell use. It also aids, both directly and indirectly, in carbon dioxide transport and regulates blood pH [24].…”
