Orthogonal alignment of DNA using hexafluoroisopropanol as solvent for film castings†
Abstract
The use of the fluorinated alcohol, 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) as a processing solvent for orthogonal alignment of a DNA–surfactant complex is reported herein. 1-butanol (BuOH) was used as the control. At low frequencies, films of DNA–CTMA cast from HFIP exhibited a higher, more consistent dielectric constant and a lower dissipation factor compared to films cast from BuOH.
