General description

Hexadecyltrimethylammonium p-toluenesulfonate is a catatonic surfactant capable of forming wormlike micelles.

Application

Hexadecyltrimethylammonium p-toluenesulfonate has been used in a study to develop a silica grafted polydentate copper (II) complex. It has also been used in a study to investigate the dispersibility and bundle defoliation of single-walled carbon nanotubes.

The integration of reactive oxygen species (ROS)-involved photodynamic therapy (PDT) and chemodynamic therapy (CDT) holds great promise for enhanced anticancer effects. Herein, we report biodegradable cancer cell membrane-coated mesoporous copper/manganese silicate nanospheres (mCMSNs) with homotypic targeting ability to the cancer
