               the mesoporous carbon film prepared by this method has excellent high mesoporous properties, high

               specific surface areas (472 m ·g ), and pore sizes of up to 9.1 nm. This directional assembly process can be
               highly regulated at the single micelle level, achieving precise thickness control of mesopores from
               monolayers to multilayers and pore size control from 8.4 to 13.5 nm. Compared to traditional porous
               carbon membrane sensors, carbon membranes with vertical mesoporous channels have high permeability,

               which shows a lower detection limit (50 nmol·L ) and higher DA detection sensitivity.
               This single micelle assembly method provides a new method for multifunctional materials related to mass
               transfer and diffusion and also plays a certain role in promoting the precise synthesis of mesoporous
               materials . However, there is still a long way to go to achieve controllable preparation of crystalline
