WebA low-pH mobile phase helps to suppress these undesirable negatively charged siloxyl groups (SiO−) on the support by converting them to neutral silanol (SiOH) groups. Acidic … Oxidized silicon has been extensively studied as a substrate for the deposition of biomolecules. Piranha solution can be used to increase the surface density of reactive hydroxyl groups on the surface of silicon. The –OH groups can hydrolyze and subsequently form siloxane linkages (Si-O-Si) with organic silane molecules. Preparation of silicon surfaces for silanization involves the removal of surface contaminants. This can be achieved by using UV-ozone and piranha solution. …
