Application

Trimethyloctylammonium chloride (TOMAC) is a cationic surfactant that can be used:
  • To separate SiC from ground SiO2 by flotation method.
  • To prepare porous organosilicates using 1,2-bis(trimethoxysilyl)ethane as a silica precursor.

The interaction of cationic surfactants with single dsDNA molecules has been studied using force-measuring optical tweezers. For hydrophobic chains of length 12 and greater, pulling experiments show characteristic features (e.g. hysteresis between the pulling and relaxation curves, force-plateau along the
