The formation of self-assembled superstructures of cetyltrimethylammonium bromide (CTAB) after drying on a nonwetting highly ordered pyrolytic graphite (HOPG) surface have been investigated using scanning electron microscopy (SEM) and atomic force microscopy (AFM). Although SEM did not reveal coverage of CTAB layers, AFM showed not only CTAB assembly, but also the dynamics of the process on the surface. The self-assembled layers of CTAB molecules on the HOPG terraces prior to nanorod deposition were shown to change the wettability of the surface, and as a result, gold nanorod deposition takes place on nonwetting HOPG terraces.

Surface Enhanced Raman

Colloidal particles are prepared with a ‘spiky’ surface topography achieved by the self-assembly of gold nanorods onto the surfaces of spherical polystyrene cores. These core–shell assemblies exhibit surface plasmon resonance properties and serve as a platform for surface-enhanced Raman spectroscopy measurements.

Novel derivatives of cationic surfactant cetyltrimethylammonium bromide (CTAB) possessing anions of ibuprofen and naproxen as hydrophobic counterions were synthesized and characterized using Fourier transform infrared and differential electronic absorption spectroscopy. The self-assembly of each surfactant was investigated using surface tensiometry. The self-immolative nature of these compounds was analyzed through study of their behavior in response to trigger such as medium pH.  ADMET-SAR (adsorption, distribution, metabolism, excretion, toxicity – structure-activity relationship) profiles of synthesized surfactants were generated using admetSAR v. 1.0). The cetrimonium drugs exhibited better profiles than the corresponding pure drugs, save the aqueous solubility which was reduced due to hydrophobicity of counterions.
